• Premature ventricular contraction (PVC) - Bigeminy OR ventricular extrasystole (VES) is a type of ectopic beat where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node, the normal heartbeat initiator • Symptoms: feeling your heart beat (palpitations); feeling of occasional, forceful beats; increased awareness of your heart beat; perception of a skipped heartbeat; dyspnea; dizziness • Causes: Adrenaline excess High blood calcium Cardiomyopathy, hy

What's really happening in a PVC? 🤔 Premature Ventricular Contractions (PVCs) are early, abnormal electrical signals from the ventricles that disrupt the heart’s normal rhythm. While they’re actually extra beats, they often feel like a skipped beat—why? A PVC comes early before the heart has time to fill with blood, creating a weak pulse that’s barely felt. The next beat, after extra filling time, is stronger, leading to that noticeable ‘thump’ in the chest. Most PVCs are harmless, but frequent

Premature Ventricular Contraction (PVC) Single ectopic beats, often benign - Bigeminy → Every other beat is a PVC - Trigeminy → Every third beat is a PVC Ventricular Tachycardia (VT) - NSVT → 3 consecutive PVCs, stops on its own (
