Arrhythmias

Learn how to take antiarrhythmic medications safely.

Learn what cardiac arrest is, what the risks are for it, and what you should do if you notice someone having cardiac arrest.

Watch this video to learn how atrial flutter affects your heart and blood flow and the best treatment options.

An arrhythmia is an abnormal heart rhythm. It may feel like fluttering or a brief pause. It may be so brief that it doesn't change your heart rate (the number of times per minute that your heart beats). Or it can cause the heart rate to be too slow or too fast. Some arrhythmias don't cause any symptoms. Others can make you feel lightheaded or dizzy. © AHA

As the name suggests, premature ventricular contractions are contractions in the lower chambers of the heart that occur too early in the rhythm sequence. These contractions, also called Paces, are common, particularly in older adults. This video discusses what effect these contractions can have on your health.

Bradycardia is when the heart beats too slowly and can cause problems. Learn how it's diagnosed, and what treatments can help.

Tachycardia is when the heart beats too fast. Find out what symptoms it causes, how it's diagnosed, and what treatments can help manage it.

Premature ventricular contractions (PVCs) are a type of abnormal heartbeat (arrhythmia). They are very common. They can occur in people of all ages from time to time. They usually cause only mild symptoms.

Your heart uses electrical signals to keep pumping normally. With right bundle branch block, some signals are slowed when they pass through the heart.

Supraventricular tachycardia (SVT) is a type of abnormally fast heartbeat. The heart normally beats 60 to 100 beats per minute. With SVT, the heart beats more than 100 times a minute. It may beat as fast as 250 times a minute.

Any abnormal change in the speed or pattern of the heartbeat is called an arrhythmia. An arrhythmia that causes the heart to beat slower than normal is called bradycardia.

First-degree heart block is a condition where the wiring of the heart is slow to send electrical signals, but all of the signals still pass successfully. It often does not cause problems.

Heart palpitations are a symptom. It's the feeling you have when your heartbeat seems to be racing, pounding, skipping, or fluttering.

Heart block is a condition in which the electrical wiring system of the heart does not work properly. Second-degree heart block causes a missed heartbeat and an irregular pulse.

A person with third-degree heart block usually has a very slow heartbeat. It is caused by a problem with how the heart's electrical system works.

Sick sinus syndrome (SSS) is a type of abnormal heartbeat, or arrhythmia. If you have SSS, you may have episodes when your heart beats very slowly, stops beating for a short while, or beats very rapidly.

An arrhythmia is a change from the normal speed or pattern of your heartbeat. Learn about the symptoms and causes and how to care for yourself when you have one.

Disorders in the heart's electrical system can lead to arrhythmias, or an abnormal heart rhythm. There are many types of arrhythmias and they're classified by where they occur in the heart and their pattern of abnormality. This segment will explain the arrhythmia known as Atrial Fibrillation.

Viewers will learn what steps they should take to manage their atrial fibrillation at home.

If you've been diagnosed with Atrial Fibrillation and you're under the care of a cardiologist, take the medications prescribed for you, and you make lifestyle changes where needed so you can live the best quality life possible.

Follow this checklist to manage your medications for atrial fibrillation.

Watch this to know when to call your doctor to avoid discomfort or any more serious problems of atrial fibrillation.

When diagnosed with atrial fibrillation, the first line treatment that cardiologists typically recommend is medications. However, over time the medications may no longer be effective or may not provide symptom relief. In these cases your health care provider may recommend a heart procedure known as catheter ablation.

Atrial fibrillation causes the heart to beat out of rhythm. To get the heart beating normally again, sometimes the heart is 'shocked' into normal rhythm. The idea of shocking the heart may be intimidating, but it's actually a quick and painless procedure.

Electrophysiology (EP) studies are tests done to find out why your heart isn't beating in a regular way. These tests study the electrical activity in your heart. They are also called cardiac mapping. The results can help your health care team find where an arrhythmia (abnormal heartbeat) is coming from and determine the best treatment for you. © AHA

In atrial fibrillation, or AFib, the heart's two small upper chambers (atria) beat irregularly and too fast, quivering instead of contracting properly. During AFib, some blood may not be pumped efficiently from the atria into the ventricles. Blood that's left behind can pool in the atria and form blood clots. © AHA

Atrial fibrillation is a condition in which the heart beats in an irregular pattern. It is caused by a problem in the heart's electrical pathways. It can be a sign of heart disease or other health problems that affect the heart.

Cardioversion is a procedure that is done to return your heartbeat to a normal rhythm. It's done when the heart is beating very fast or irregular.

Cardioversion is a procedure that is done to return your heartbeat to a normal rhythm. You take medicine, either through an IV or by mouth.
