Individual conditions vary.
Please consult your own physician first. An arrhythmia is an abnormal heart rhythm, a change in either the pace or pattern of the heartbeat. The heart may be beating too slowly, too rapidly or irregularly. An abnormal heart rhythm may cause a skipping or fluttering sensation in the chest. More serious rhythm disturbances may cause lightheadedness, fainting or shortness of breath.
