Cardiac arrhythmia is a disease that affects the electrical system of the heart. When electrical impulses that coordinate heartbeats aren’t timed properly, the heart can beat too fast, too slow, or irregularly.

These abnormal heartbeat variations can include ventricular tachycardia, Wolff-Parkinson-White Syndrome, supraventricular tachycardia, varying congenital conditions and other defects that if left untreated can lead to stroke, other serious complications and even death.
