Arrhythmia: It can be a sign of an abnormality in the electrical pathway and is cause for evaluation. Abnormal rapid heart rates can range from 100 beats a minute up to 400 beats a minute and can be relatively harmless or life threatening. Ask your doctor to refer you to a heart rhythm specialist (an electrophysiologist), for further evaluation. Call 911 if passing out, dizziness, chest pain, or breathless.
