Nonsustained ventricular tachycardia (NSVT) has been recorded in a wide range of conditions, from apparently healthy individuals to patients with significant heart disease. In the absence of heart disease, the prognostic significance of NSVT is debatable. When detected during exercise, and especially at recovery, NSVT indicates increased cardiovascular mortality within the next decades. In trained athletes, NSVT is considered benign when suppressed by exercise. In patients with non-ST-segment elevation acute coronary syndrome, NSVT occurring beyond 48 h after admission indicates an increased risk of cardiac and sudden death, especially when associated with myocardial ischemia. In acute myocardial infarction, in-hospital NSVT has an adverse prognostic significance when detected beyond the first 13 to 24 h. In patients with prior myocardial infarction treated with reperfusion and beta-blockers, NSVT is not an independent predictor of long-term mortality when other covariates such as left ventricular ejection fraction are taken into account. In patients with hypertrophic cardiomyopathy, and most probably genetic channelopathies, NSVT carries prognostic significance, whereas its independent prognostic ability in ischemic heart failure and dilated cardiomyopathy has not been established. The management of patients with NSVT is aimed at treating the underlying heart disease.

“…Additionally, VT ablation is indicated for control of incessant monomorphic VT or VT storm that is not due to a transient reversible cause; for patients with frequent premature ventricular contraction, NSVT, or VT that results in ventricular dysfunction (due to tachycardiainduced cardiomyopathy); for patients with bundle branch re-entry or intrafascicular VTs; and for patients with recurrent sustained polymorphic VT or VF that is refractory to antiarrhythmic medications when there is a suspected trigger that can be identified and targeted for catheter ablation [30]. Catheter ablation is being performed with increasing frequency as a primary treatment for VT, particularly in patients receiving multiple ICD shocks and with prior infarct scar [14,31]. Recent data suggest that prophylactic substrate-based catheter ablation may reduce the incidence of ICD therapy in patients with a history of myocardial infarction who received an ICD for secondary prevention of sudden death [14].…”

Treatment of Ventricular Tachycardia in Patients with Heart Failure

Heart failure is a major public health concern that is frequently complicated by ventricular arrhythmias. Sustained ventricular tachycardia is associated with an increased risk for progressive heart failure and sudden death. We summarize the current management strategies for ventricular tachycardia in heart failure patients, including implantable cardioverter-defibrillator therapy, pharmacologic therapy, catheter ablation techniques, ventricular assist device therapy, and heart transplantation.

“…1 However, some patients suffer from syncope or even sudden cardiac death (SCD) due to hemodynamically unstable, fatal VT, or ventricular fibrillation (VF). 2 Previous studies have determined that catheter ablation of malignant VT or idiopathic VF, targeting the triggering PVC, may be effective in preventing recurrence of clinical events.…”
