Figure 1 Programmed implantable cardioverter-defibrillator (ICD) therapies versus heart rate. (A) Percentage of all patients programmed to antitachycardia pacing (ATP) and/or shock therapy (number of patients with ATP or shock therapy on at each heart rate/total number of patients in the arm). The dotted line illustrates that nearly all EMPIRIC arm patients had their ICD enabled to treat tachycardias >150 beats/min. In marked contrast, tailored programming was enabled to treat slower tachycardias in a much smaller proportion of patients. (B) Percent of treated patients programmed to ATP on (number of patients with ATP on at each heart rate/number of patients with ATP or shock therapy on at each heart rate). The dotted line illustrates that nearly all EMPIRIC arm patients had ATP on up to 250 beats/min. In marked contrast, a small proportion of tailored arm patients had ATP on at faster heart rates.
