Sinus rhythm with PVCs refers to a heart rhythm that originates from the sinoatrial (SA) node, which is the natural pacemaker of the heart, but is interrupted by occasional premature ventricular contractions. The SA node generates electrical impulses that travel through the atria and ventricles, causing them to contract and pump blood. However, when PVCs occur, they are early heartbeats that start in one of the ventricles before the next SA node impulse, causing the ventricle to contract prematurely. These premature beats can sometimes be felt as a fluttering sensation or a skipped beat, and they can be harmless or indicative of an underlying heart condition. Not all PVCs require treatment, but they should be evaluated by a healthcare professional to determine their cause and appropriate management. read more >>

Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest.read more >>
