Reducing base rate to 50 bpm may shorten pacing time and improve preference in sinus node disease; hypothesis-generating and requires confirmation in larger trials.
Does pacing at 50 bpm or using rate hysteresis reduce total pacing time compared to 70 bpm in patients with sinus node disease?
In paced patients with sinus node disease, reducing the stimulation rate to 50 bpm decreases total pacing time and is preferred by patients over 70 bpm or hysteresis pacing.
