Ventricular fibrillation (VF) may be coarse or fine rapid, fibrillary movements of the ventricular muscle, Factors that commonly precipitate cardiac arrhythmias include hypoxia, electrolyte disturbance, myocardial ischemia and certain drugs. Symptoms during arrhythmia may be syncope, palpitation, breathlessness and sudden loss of consciousness. Approximately 10% of patients with AMI develop VT that degenerates into VF. This may occur in the settings of acute myocardial infarction (AMI) in thrombolytic patients. We present 3 cases of VF during and immediately after thrombolysis, which are reverted to normal with prompt cardioversion.
