Extreme slowing or complete stopping of the heartbeat can be fatal. In other cases, people may have no symptoms but are at high risk for dangerously slow heart rates because of disturbances of the electrical system of the heart. A pacemaker may be recommended for these people before symptoms occur. There are no electrical disturbance shown with your post?!
