Fig. 2From: Clinical significance of precedent asymptomatic non-sustained ventricular tachycardias on subsequent ICD interventions and heart failure hospitalization in primary prevention ICD patientsSubgroup Kaplan–Meier analyses of appropriate ICD therapy according to the presence of precedent non-sustained ventricular tachycardia. In both patients with ischemic (a) and non-ischemic cardiomyopathy (b), precedent non-sustained ventricular tachycardia was associated with subsequent appropriate ICD therapy (log-rank, P < 0.0001, and P = 0.0083, respectively)Back to article page
