Premature Contractions

Extra, early, or "skipped" beats are the most common cause of irregular heart rhythms. These can start in the upper or lower chambers of the heart (atrial or ventricular premature contractions). They may or may not cause symptoms of chest discomfort, palpitations, "fluttering", or feeling lightheaded. Often they require no treatment but if they are frequent or highly symptomatic a medical and cardiac evaluation should be undertaken.

  • Pulse that is changing between fast and slow and feels irregular
  • Pain, pressure, tightness, or discomfort in your chest
