[Presyncope caused by non-sustained ventricular tachycardia. Significance of RF ablation].
We describe a case of a 55-year-old man with episodes of presyncope caused by non-sustained ventricular tachycardia (ns-VT). Symptoms of significant weakness started when he was 30-year-old. In the last 2 years there was a substantial increase in frequency of presyncope from 2 per month to 8 per week. He does not have palpitations. Standard ECG, echocardiography and coronary angiography were normal. During an exercise test ns-VT 220/min (5 s, 20 x QRS) with LBBB morphology was documented. Successful RF ablation of ns-VT using the CARTO system was performed. During 4-month follow-up the patient remains free from ventricular arrhythmia.
