Did you think about your heartbeat today?
If you’re like most Americans, you probably didn’t give it much thought, even though your heart was beating constantly, anywhere from 60 to 100 beats a minute.
Normally, the heart’s electrical system causes the heart muscle to contract in a regular, controlled pattern. However, a problem anywhere along the electrical pathway causes a disturbance in the heart rhythm. This could lead to an irregular heart rhythm or a heart rate that’s too fast or too slow.
