Non-Sustained, Symptomatic Ventricular Tachycardia: A Case Report and Literatures Review

Non-sustained ventricular tachycardia (NSVT) is commonly seen but poorly understood. Patients with NSVT might be asymptomatic or encountered sudden cardiac death. The prognosis depends on what the concomitant heart disease is. Poor prognosis were found in patient with NSVT during or post exercise; acute myocardial infarction more than 24 hours; chronic ischemic heart disease with left ventricular ejection fraction (LVEF) below 40% with/without inducible sustained ventricular tachycardia in electrophysiology testing; and hypertrophic obstructive cardiomyopathy in the young. Medical therapy including beta-blockers and class III antiarrhythmic agents, while implantable cardiac defibrillators (ICD) and radiofrequency ablation are indicated in certain patients. Here, we report a case that had near syncope and palpitation with NSVT on 24-hours electrocardiography, finally received ablation and antiarrhythmic therapy. No more arrhythmia was found during out patient department follow up.
