Tell me about the types of irregular heart beat.
Atrial fibrillation is a very common irregular heart rhythm that causes the atria, the upper chambers of the heart, to contract abnormally. Atrial flutter. This is an arrhythmia caused by one or more rapid circuits in the atrium.
How serious is an irregular heart beat?
Coronary artery disease can cause dangerous arrhythmias like atrial fibrillation, or AFib. It's a rapid, quivering heartbeat that can lead to heart palpitations, blood clots, heart attack and stroke.
What are the different types of tachycardia?
Atrial fibrillation. Atrial fibrillation is a rapid heart rate caused by chaotic, irregular electrical impulses in the upper chambers of the heart (atria). ...Atrial flutter. ...Supraventricular tachycardia (SVT). ...Ventricular tachycardia. ...Ventricular fibrillation.
What is atrial flutter?
Atrial flutter (AFL) is a type of abnormal heart rate, or arrhythmia. It occurs when the upper chambers of your heart beat too fast.
What causes irregular heartbeat?
They can be related to stress or too much caffeine or nicotine. But sometimes, PVCs can be caused by heart disease or electrolyte imbalance.
What's the difference between flutter and fibrillation?
In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, so you may have four atrial beats to every one ventricular beat.
How does atrial fibrillation affect electrocardiography?
The symptoms of atrial fibrillation are related to the loss of atrial mechanical activity (atrial contraction) and rapid ventricular heart rates, both of which can reduce cardiac output and lead to congestive heart failure.
Does atrial flutter shorten your life?
People can live long, healthy and active lives with AFib. Controlling your risk factors for heart disease and stroke and knowing what can possibly trigger your AFib will help improve your long-term management of AFib.
