This is similar to A-fib, but the rhythms are more organized. Many people have both A-fib and atrial flutter. Abnormal electrical signals in the lower chambers result in a rapid heart rate. This can result from cardiovascular problems, such as a previous heart attack, and the use of certain drugs. The speed of the heartbeat does not allow the ventricles to fill and contract properly, thereby reducing blood supply to the body.
Ventricular fibrillation V-fib is a serious cardiac disturbance. The ventricles quiver instead of beating, resulting in poor blood supply to the body. V-fib is a medical emergency. If a normal heart rhythm does not return quickly, blood circulation can cease, which can lead to death.
