Figure 2 Time-Dependent Occurrence of Inappropriate Shock by Type

The cumulative proportion of patients experiencing a first inappropriate (Inapp.) shock due to the 3 subcategories of inappropriate shock is plotted with respect to time. The number of patients at risk at a given time point of follow-up is indicated below the x axis. The proportion of the population experiencing the event in question is given in parentheses at the 1-, 2-, and 3-year time points. AF = atrial fibrillation or atrial flutter; ICD = implantable cardioverter-defibrillator; SVT = supraventricular tachycardia.
