Pacemakers of all the eligible patients were programmed to have: (1) A lower rate limit of 60 beats/min; (2) a maximum sensor rate equal to the maximum predicted heart rate (220−age); and (3) DDDR therapy mode; (4) dynamic atrioventricular delay mode was programmed ON, providing a shorter atrioventricular delay at faster heart rate; (5) recording method was programmed to high resolution at which setting the ventricular rate was averaged and recorded every 16 s and the ACC and MV raw sensor data were collected; (6) the sensor response factors were programmed passive during the treadmill testing and converted to the default settings of ACC = 8, MV = 3 when analyzing the SIR data; (7) the baseline sensor rate was set accordingly with the sinus rate at rest.

Of 40 pacemakers 15 were programmed to VVIR, 11 DDDR, 7 DDD, and 7 VDDR modes.
