Premature Contractions

Extra, early, or “skipped” beats are the most frequent cause of irregular heart rhythms.

These early, extra beats are weak and may not be felt in the chest or in the pulse at the wrist, which is why symptoms are frequently described as “skipped” beats. Extra beats can come from either the upper chambers (premature atrial complexes, PACs), or the lower chambers (premature ventricular complexes, PVCs) of the heart.
