heart arrhythmia death

The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart's lower chambers). When this occurs, the heart is unable to pump blood and death will occur within minutes, if left untreated.

The heart rate may be too slow or too fast; it may stay steady or become chaotic (irregular and disorganized). Some arrhythmias are very dangerous and cause sudden cardiac death, while others may be bothersome but not life threatening. They can result in a stroke or heart attack, which can be devastating.

Arrhythmia contributes to approximately 200,000-300,000 sudden deaths per year – a higher incidence than stroke, lung cancer or breast cancer. Cardiologists can help people live with some forms of arrhythmia, but the abrupt and deadly arrhythmias keep researchers and physicians awake at night.
