Abnormal heart rhythms. An abnormal heart rhythm â sometimes called an arrhythmia â means your heart is beating too fast, too slow, or with an irregular pattern. Your heart has an electrical system that tells it when to beat and push blood around the body. If there is a problem with this system you may experience an abnormal heart rhythm.
Sinus bradycardia: A regular but unusually slow heart beat (50 beats/minute or less at rest). Sinus bradycardia can be the result of many things including good physical fitness, medications, and some forms of heart block. Sinus refers to the sinus node, the heart's natural pacemaker which creates the normal regular heartbeat. Bradycardia means that the heart rate is slower than normal. Fainting can occur with sinus bradycardia if the heart slows down even more. This can occur, for example, when the vagus nerve sends a signal to the heart that suddenly drops the heart rate. Choking or gagging can trigger this response which is called the vasovagal reflex.
