What Is an Arrhythmia?

An arrhythmia is an irregular heartbeat. It means your heart is out of its usual rhythm.

It may feel similar your center skipped a beat out, added a beat, or is "fluttering." Information technology might feel like information technology'due south beating besides fast (which doctors phone call tachycardia) or too deadening (called bradycardia). Or you might non notice anything.

Arrhythmias can be an emergency, or they could be harmless. If you feel something unusual happening with your heartbeat, become medical assist right abroad so doctors tin can find out why information technology's happening and what you need to practise about it.

What Are the Symptoms of Arrhythmia?

An arrhythmia tin can be silent, meaning you don't notice any symptoms. Your md may spot an uneven heartbeat during a physical examination.

If you have symptoms, they may include:

• Palpitations (a feeling of skipped heartbeats, fluttering, or "flip-flops")
• Pounding in your chest
• Dizziness or feeling featherbrained
• Fainting
• Shortness of breath
• Chest pain or tightness
• Weakness or fatigue (feeling very tired)
• Feet
• Blurry vision
• Sweating

What Causes Arrhythmia?

Yous could take an arrhythmia even if your eye is salubrious. Or it could happen because of:

• Heart affliction
• The wrong residue of electrolytes (such as sodium or potassium) in your blood
• Heart injury or changes such as reduced blood flow or stiff heart tissue
• Healing process later middle surgery
• Infection or fever
• Certain medications
• Problems with the electrical signals in your heart
• Stiff emotions, stress, or surprise
• Things in your daily life similar alcohol, tobacco, caffeine, or exercise

What Are Some Arrhythmia Risk Factors?

Things that may brand yous more than probable to take an arrhythmia include your:

• Age. The chances go up as you lot get older.
• Genes. Your odds might be higher if a close relative has had an arrhythmia. Some types of heart disease can as well run in families.
• Lifestyle. Booze, tobacco, and recreational drugs tin heighten your risk.
• Medical conditions.High claret pressure, diabetes, low blood sugar, obesity, slumber apnea, and autoimmune disorders are amidst the conditions that may crusade heart rhythm problems.
• Environment. Things in the earth around you lot, similar air pollution, tin make an arrhythmia more likely.

What Are the Types of Arrhythmias?

Arrhythmias are divided up by where they happen. If they start in the ventricles, or lower chambers of your heart, they're chosen ventricular. When they begin in the atria, or upper chambers, they're called supraventricular.

Doctors also group them by how they affect your resting heart rate. Bradycardia is a heart charge per unit of fewer than 60 beats per infinitesimal. Tachycardia is more than 100 beats per infinitesimal.

Supraventricular arrhythmias include:

• Premature atrial contractions. These are early extra beats. They're harmless and generally don't need handling.
• Atrial fibrillation (AFib). The upper chambers of your center contract in an unusual way. Your heart might beat more than 400 times a minute.
• Atrial flutter . This is usually more organized and regular than atrial fibrillation. It happens most oftentimes in people who take center disease and in the beginning calendar week afterwards heart surgery. Information technology often changes to atrial fibrillation.
• Paroxysmal supraventricular tachycardia (PSVT). This is a rapid heart rate, usually with a regular rhythm. It begins and ends suddenly.
• Accessory pathway tachycardias. You tin have a rapid heart rate because of an extra pathway between your heart's upper and lower chambers. Call up of it as an actress road on your style home besides as your usual route. When that happens in your centre, information technology can cause a fast rhythm.
• AV nodal reentrant tachycardia (AVNRT). This is caused past an extra pathway through a part of your centre called the AV node. It can crusade heart palpitations, fainting, or middle failure.

Ventricular arrhythmias include:

• Premature ventricular contractions (PVCs). These are among the most common arrhythmias. They're the "skipped heartbeat" that many of us feel sometimes.
• Ventricular tachycardia (V-tach). This is a rapid heart rhythm starting from your heart'due south lower chambers. Because your center is chirapsia too fast, information technology tin't fill with enough blood. This can be a serious arrhythmia, especially in people who have middle disease, and it may exist linked to other symptoms.
• Ventricular fibrillation (V-fib). This happens when your heart's lower chambers quiver and can't contract or pump claret to the rest of your body. Information technology's a medical emergency that must exist treated with CPR and defibrillation equally shortly equally possible.
• Long QT syndrome. Your centre's lower chambers take likewise long to contract and release. This may cause dangerous rhythm problems and decease.

Another type of arrhythmia, bradyarrhythmia, is a deadening rhythm because of disease in your heart's electrical system or because of medication. It may make you pass out or feel similar you will. Types of bradyarrhythmia include:

• Sinus node dysfunction. This is caused past a problem with your heart'southward sinus node, its natural pacemaker.
• Heart block. In that location's a filibuster or a block of the electrical impulse as it travels from your heart's sinus node to its lower chambers.

How Are Arrhythmias Diagnosed?

To diagnose an arrhythmia or find its cause, doctors employ tests including:

• EKG . An electrocardiogram records the electrical activity of your heart. You lot wear small electrode patches on your chest, arms, and legs for the quick, painless exam, which you take in your physician's part.
• Holter monitor. This is a portable EKG (also called an "ambulatory electrocardiogram" or an ECG) about the size of a postcard or digital photographic camera that you'll use for one to ii days, or upward to two weeks. The test measures the movement of electrical signals or waves through your center. These signals tell your heart to contract (squeeze) and pump blood.  You lot'll have electrodes taped to your peel. It's painless, although some people take mild pare irritation from the tape used to attach the electrodes to the breast. Y'all can do everything just shower or bathe while wearing the electrodes. After the test period, you lot'll go back to see your physician. They'll download the information.
• Result monitor. If your symptoms don't happen often, your doctor may advise that you wear i of these, usually for about a month. When you push a button, it records and stores your heart's electric activity for a few minutes. Try to get a reading when you notice symptoms. Your doctor volition interpret the results.
• Implantable loop recorder. Your doctor puts this nether your skin, where information technology constantly records your heart'south electrical activity. It tin can send information to your doctor's part.
• Stress test . There are different kinds of stress tests. The goal is to bank check how much stress your heart can manage before having a rhythm problem or not getting enough blood. For the almost common type of stress test, you lot'll walk on a treadmill or pedal a stationary bike while you lot get an EKG and have your centre rate and blood pressure monitored. Technicians slowly heighten the intensity level of your do.
• Echocardiogram. This exam uses ultrasound to check your heart muscle and valves.
• Cardiac catheterization. Your doctor volition insert a long, thin tube, called a catheter, into a blood vessel in your arm or leg. They'll guide information technology to your heart with help from a special X-ray machine. Then, they'll inject dye through the catheter to assistance make X-ray videos of your heart valves, coronary arteries, and chambers.
• Electrophysiology study. This test records your heart's electric activities and pathways. Information technology can help find out what's causing eye rhythm problems and notice the best treatment for you. During the examination, your md volition safely trigger your unusual eye rhythm. Then, they may give you medications to see which one controls it best or to see what procedure or device you demand to treat information technology.
• Caput-up tilt table test. Doctors apply this test to find out what'due south causing fainting spells. It measures the difference in heart rate and claret pressure when you're standing up and lying downwards. You'll get this exam in a lab. Yous'll lie on a stretcher, tilted at dissimilar angles while you get an EKG and specialists check your claret pressure and oxygen level. This shows if symptoms of passing out are due to your electrical organization, nervous arrangement, or vascular system.

How Are Arrhythmias Treated?

Treatment will depend on what type of arrhythmia you have. Your medico may recommend 1 or more of these.

Medications

Medicines that treat uneven heart rhythms include:

• Adenosine (Adenocard)
• Atropine (Atropen)
• Beta-blockers
• Calcium aqueduct blockers
• Digoxin (Digitek, Digox, Lanoxin)
• Potassium channel blockers
• Sodium channel blockers

Vagal maneuvers

These techniques trigger your torso to relax by affecting your vagus nerve, which helps command your eye rate. Your doctor might tell you lot to:

• Cough or gag
• Hold your jiff and bear downward (Valsalva maneuver)
• Prevarication down
• Put a cold, wet towel over your confront

Electrical cardioversion

If drugs tin't command an uneven heart rhythm (such as atrial fibrillation), you lot might demand cardioversion. For this, doctors put you nether and then transport an electrical daze to your chest wall to trigger your heart'due south regular rhythm.

Pacemaker

This device sends small electrical impulses to your middle muscle to keep a condom centre rate. It includes a pulse generator, which houses the battery and a tiny computer, and wires that send impulses to the eye musculus.

Implantable cardioverter defibrillator (ICD)

Doctors mainly utilise ICDs to treat ventricular tachycardia and ventricular fibrillation, two life-threatening heart rhythms.

The ICD constantly tracks your middle rhythm. When information technology detects a very fast, unusual rhythm, it delivers an electric shock to the heart muscle to make it beat out in a regular rhythm again. The ICD has two parts: the leads and a pulse generator. The leads are made up of wires and sensors that monitor the eye rhythm and deliver energy used for pacing or defibrillation. The generator houses the bombardment and a tiny computer. Energy is stored in the battery until information technology is needed. The reckoner receives information from the leads to determine how the center is beating.

Your doctor programs the ICD to include 1 or all of the following functions:

• Anti-tachycardia pacing (ATP). A series of small electrical impulses to the heart muscle restores a regular rate and rhythm.
• Cardioversion. You may get a low-energy shock at the same time your heart beats to restore regular rhythm.
• Defibrillation. When your heartbeat is dangerously fast or uneven, your centre muscle gets a college-energy shock to restore a regular rhythm.
• Anti-bradycardia pacing. Many ICDs give fill-in pacing to continue the eye rhythm if it slows too much.

There are different types of ICDs, including:

• Unmarried-chamber ICD. A lead is fastened in the right ventricle. If needed, energy is delivered to the ventricle to restore a normal heart rhythm.
• Dual-bedchamber ICD. Leads are attached in the right atrium and the right ventricle. Energy tin be delivered to the right atrium and then to the correct ventricle, helping your heart to exist paced in a normal sequence.
• Biventricular ICD. Leads are attached in the correct atrium, the correct ventricle, and the coronary sinus next to the left ventricle. This technique helps the middle beat in a more than efficient mode and is specifically used for patients with eye failure.

Your doctor volition determine which type of ICD is best for you lot. Earlier y'all have your ICD implanted, ask your doctor what medications you can take. Your doctor may ask y'all to stop taking sure medications before the process. You will receive specific instructions.

Afterward information technology's implanted, you might not notice a low-energy shock. Or it may feel like a flutter in your breast. The high-energy shock lasts just a second, only it can hurt. Some people say it feels like being hit with a baseball game bat or being kicked by a horse. Well-nigh people feel information technology more in their back than their breast. If you lot feel a shock, sit or prevarication downward because you may pass out.

Talk to your doctor well-nigh what to do if y'all always get shocked. If you do get shocked, telephone call your doc immediately.

Catheter ablation

Recollect of this process as rewiring to fix an electric problem in your center.

Your doctor will insert a catheter through your leg. It delivers high-frequency electrical energy to a small area inside your heart that causes the unusual rhythm. This energy "disconnects" the pathway of the unusual rhythm.

Doctors use ablation to care for most PSVTs, atrial flutter, atrial fibrillation, and some atrial and ventricular tachycardias.

Eye surgery for arrhythmias

The maze procedure is a type of surgery to correct atrial fibrillation. Your surgeon makes a series, or "maze," of cuts in your heart'south upper chambers. The goal is to keep your eye's electric impulses only on sure pathways. Some people need a pacemaker afterward.

Your physician might recommend other procedures, such as a coronary bypass, to treat other forms of eye disease.

Complications of Arrhythmias

Without treatment, an uneven heart rhythm could cause unsafe issues such equally:

• Alzheimer's affliction and dementia . These cognitive disorders may happen because your brain doesn't go enough blood over time.
• Center failure . Your heart might not pump likewise as it should subsequently repeated arrhythmias.
• Stroke . Blood that lingers in your atria tin clot. If a clot travels to your brain, information technology may crusade a stroke.
• Cardiac arrest. V-fib could cause your centre to stop.

Safe Driving Concerns

If you have an arrhythmia, you could faint behind the bike. This could put you, other motorists, pedestrians, and property at great gamble.

To figure out whether you can bulldoze safely, your doctor volition consider:

• What blazon of arrhythmia you lot have
• How serious yours is
• The treatment you receive for it (if any)
• How oftentimes you lot have symptoms and how serious they are

If you have no symptoms and you haven't had whatsoever serious heart rhythm problems, you should be able to drive every bit y'all always have. If meds keep your arrhythmia under command, your doctor may give you the green light to bulldoze, too.

In addition to meds to help manage your heart rhythm, you may have ii other treatments. Both would keep yous out of the driver's seat for a while:

Ablation: This treatment will usually restrict yous to the rider's seat for about a week. It may keep you in that location longer, depending on your medical history.

Implantable cardioverter defibrillator: Usually after you get an ICD, y'all'll be asked non to drive for a week. If you got an ICD later fainting or surviving cardiac arrest, you may have to wait several months before you become back behind the wheel.

You lot tin can't bulldoze commercially (as in a delivery truck or a taxi) at all if you lot take an ICD.

Arrhythmia Prevention

You tin't ever prevent arrhythmias. Regular checkups with your doctor tin can help proceed you lot from having more middle rhythm bug. Be sure they know all of the medications yous're taking. Some cold and coughing medicines tin trigger an arrhythmia, so talk to your medico earlier using them.

They may also recommend some lifestyle changes:

• Eat a good for you diet. Get plenty of fruits and vegetables, fish, and constitute-based proteins. Avoid saturated and trans fats.
• Continue cholesterol and blood pressure under control.
• Don't smoke.
• Keep a healthy weight.
• Exercise regularly.
• Manage stress.
• Limit booze and caffeine.
