Premature Contraction (PC)
Extra, abnormal heartbeats generated in abnormal locations of your heart,
either in the atria (PAC) or in the ventricles (PVC) or in the cardiac conduction
nodes (PNC). These extra beats disrupt your regular heart rhythm, sometimes
causing palpitations (e.g. skipped beats) in your chest. May occur singular or
repeated with various incidence. If not stress-related, they are a sensitive
marker for a multitude of cardiac disorders and elevated ischemic stroke risk.
