Ventricular Arrhythmias : These include premature ventricular contractions (PVC), ventricular tachycardia (VT) and ventricular fibrillation (VT). At times they may be responsible for sudden cardiac death in the post-operative period. So these patients are closely monitored in the first 48 hours. Electrolyte imbalance or ischaernia of the myocardium may trigger ventricular irritability. Coirection of electrolyte and acid base imbalance and judicious use of anti arrhyhnic agents help in the management of ventriculx arrhythmias. Atrial and ventricular pacing wires inserted at the time of surgery help in managing post-operative arrhythmias. Cardioversion with synchronized shock and defibrillation will be life saving.
