An arrhythmia is a problem with the rate or rhythm of the heartbeat. It may involve the heart beating too fast, too slow or with another form of irregularity. When the heart beats too fast, it is called tachycardia. A slow heartbeat is called bradycardia. ...

While your heart may be beating faster than at rest in sinus tachycardia, it is not interfering with other electrical impulses in the heart. 1 Atrial or supraventricular tachycardia (SVT) An abnormally fast heart rate that begins in the upper chambers of the heart is called atrial or ...

For persons with Sick Sinus Syndrome, the arrhythmia takes the heart someplace else entirely – someplace too fast (tachycardia), too slow (bradycardia), too irregular (and sometimes a combination of all those) – someplace away from that steady drum beat that our bodies so need. Sick Sinus...
