• 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

Post op cardiac patient had this rhythm in the ECG trace in the monitor. Its ventricular Bigeminy. One can see each normal beat is alternating with a ventricular premature complex (VPC). If you see the arterial line trace below it, during the VPC there is no effective contraction as shown by very small amplitude arterial waveform :) | Medical Snippet

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 (
