Irregular Heartbeat
There are many potential causes of irregular heartbeats. Alcohol abuse, anxiety, inherited conditions, salt imbalances, heart attacks, hormone imbalances and certain medications can all trigger irregular heartbeats. An irregular heartbeat can occur for only a few seconds once a month or it can be continuous for many years.

Tachycardia -- a fast heart rhythmwith a rate of more than 100 beats per minute.
Bradycardia -- a slow heart rhythm with a rate below 60 beats per minute.
Supraventricular arrhythmias -- arrhythmias that begin above the ventricles, such as in the upper chambers, or atria. "Supra" means above; "ventricular" refers to the lower chambers of the heart (ventricles).
