There are many different types of abnormal heart rhythm. What type you have depends on where in your heart the rhythm (electrical impulse) starts, and whether it causes your heart to beat too fast, or too slow. The most common abnormal rhythm is atrial fibrillation.
Heart muscle damage resulting from a heart attack is another common cause of disruptions of your heartbeat. Some medications can affect your heart rate as well. For some, genetic conditions cause an abnormal heart rate. Regardless of the underlying cause of an abnormal heart rate, a pacemaker may fix it. A pacemaker can often be implanted in your chest with a minor surgery.
