An arrhythmia is an abnormal heart rhythm that can cause problems with the contractions of your heart chambers.
Atrial fibrillation, or AFib, is a kind of abnormal heart rhythm or arrhythmia. Afib increases the risk for blood clots. These clots can then travel to the brain, causing a stroke. This is why AFib significantly increases the risk for stroke.
Atrial flutter is an abnormal heart rhythm that causes the atria to beat more quickly than they should.
When you have heart block, there is interference with the electrical signals that usually move from the top chambers of your heart to the bottom chambers, telling your heart when to beat.
Long QT Syndrome
Your heartbeat is a complex bodily function — many systems must work in unison. Disruptions in the electrical activity of your heart can lead to problems. Long QT syndrome (LQTS) is one of them.
Sick Sinus Syndrome
Sick sinus syndrome is a type of abnormal heartbeat, or arrhythmia. If you have sick sinus, you may have episodes when your heart beats very slowly, stops beating for a short while, or beats very rapidly. Sick sinus syndrome is not just one disease, but a collection of arrhythmias.
Ventricular fibrillation is a type of arrhythmia, or irregular heartbeat, that affects your heart’s ventricles.
Ventricular tachycardia is a rapid heart rate that begins in your heart’s lower chambers, or ventricles. Experts describe it as three or more heartbeats in a row, at a rate of more than 120 beats a minute.
Wolff-Parkinson-White syndrome (WPW) is a type of abnormal heartbeat. If you have WPW, you may have episodes of tachycardia, when your heart beats very rapidly
Automated External Defibrillator
An AED is a small, portable, battery-powered machine with a computer in it. The machine detects heart activity. It can give an electric shock to someone if needed.
