Table 3: Optimal Programming of the Closed Loop Stimulation Algorithm for Vasovagal Syncope Patients.

Turn Resting Rate Control to “off”. This allows the closed loop stimulation (CLS) algorithm to vary rate response from base rate to the maximum programmed CLS rate based on cardiac impedance measurement variations, enabling intervention much earlier Set the mode to “DDD-CLS Program”, with base/lower rate of 60-65 BPM, upper tracking rate of 160 BPM, and maximum CLS rate (akin to maximum sensor rate) to between 130 and 140 BPM. Set the CLS response (aggressiveness of the CLS algorithm) to “high” or “very high”. Atrioventricular (AV) delay is programmed to minimise ventricular pacing using the AV hysteresis function of the pacemaker.
