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.

This video helps you to understand what happens in the body when you have Bradycardia (slow heart rate).

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.

An arrhythmia is an abnormal heart rhythm that can cause problems with the contractions of your heart chambers.

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.

Watch this video to learn about ways to manage symptoms of atrial fibrillation.

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

Watch this video to learn how atrial fibrillation affected three people's lives and how each one found a way to manage it.

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.

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.

John Criswell explains atrial fibrillation, it's symptoms, causes, and the importance of treating it.

Watch how Kersey has lived and made lifestyle changes after being diagnosed with heart disease.

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, or A-fib, is a common type of heart arrhythmia. It causes fast, chaotic electrical signals in the atria.
