Electrophysiological assessment in patients with recurrent ventricular tachycardia after myocardial infarction


Respiration & Circulation 33(6): 771-776
Electrophysiological assessment in patients with recurrent ventricular tachycardia after myocardial infarction
Six patients with symptomatic ventricular tachycardia (VT) after myocardial infarction were investigated. VT were identified in 3 (50%) by 24 h Holter recording and 2 (33%) by exercise electrocardiography. These patients underwent electrophysiological study and VT were induced by using programmed ventricular electrical stimulation in all patients (100%). The induction of VT were achieved in 3 patients by single extra ventricular stimulus after basic ventricular pacing and in 2 patients by rapid ventricular pacing. Sustained VT occurred in 3 patients. Single ventricular extra ventricular stimulus or rapid ventricular pacing successfullly terminated sustained VT. The QRS configulation of induced VT were compared with clinical VT and were the same. Programmed ventricular stimulation for paroxymal VT after myocardial infarction were useful in those patients with rare occurrence of tachycardia attack, induced VT showed similar QRS configulation to clinical VT and drug efficacy and patients prognosis was assessed by induced VT.
