Rate responsive pacing using intracardiac impedance to measure sympathetic activity provides physiological rate adaptation during exercise in patients with AV block.
Schaldach et al. (1992) studied AV block. ANS-controlled stimulation rate using intracardiac impedance vs. Spontaneous sinus rhythm was evaluated on Agreement between spontaneous sinus rhythm and ANS-controlled stimulation rate during exercise. ANS-controlled stimulation rate using intracardiac impedance demonstrated excellent agreement with spontaneous sinus rhythm during exercise in patients with AV block.
