Figure 1. Associations of Titin-Truncating Variants (TTNtvs) With Implanted Cardioverter Defibrillator (ICD) Therapy for Ventricular Tachycardia or Ventricular Fibrillation.

Kaplan-Meier plots for appropriate ICD therapy (antitachycardia pacing or shock) (A) or appropriate shock for ventricular tachycardia more than 200 beats/min or ventricular fibrillation (B). Crosses indicate censoring; CRT-D, cardiac resynchronization therapy defibrillator; and HR, hazard ratio.
