Now that you have seen a normal heart rhythm, let's look at what happens in the heart's electrical pathways during an abnormal heartbeat. An abnormal heartbeat is a heart rhythm problem called an arrhythmia.
Sometimes, things go wrong in the heart's electrical pathways. An electrical signal may be sent from a part of the heart that should not be sending signals. This creates abnormal heartbeats. The heart may beat too slowly, too rapidly, or just irregularly.
The end result of abnormal heartbeats is that your heart may not be able to pump blood to your body and your brain effectively. This condition can cause minor problems or very serious life-threatening situations.
