Abnormal heartbeats, called arrhythmia, or slower or faster heartbeats, called bradycardia and tachycardia, respectively, are dangerous medical conditions which often appear as a result of an underlying condition. One of these is disorders is sudden arrhythmic death syndrome, or SADS. SADS is a condition caused by a hereditary genetic defect which can be triggered by high heart rates (from exercise, for example) or extreme emotional distress. As a result, people with the defect who may be otherwise young and healthy have been known to simply and unexpectedly "drop dead". The condition can be treated with a defibrillator implant, however it is not usually detected until the subject has been observed to have an attack, and such attacks are usually fatal.

 

A [[Myocardial infarction|myocardial infarction]], more commonly known as a heart attack, occurs when the blood vessels which supply the hearts muscle tissue become partially or totally blocked. Heart attack is the number one cause of death in America.
