• 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

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 (

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
