Cardiac Resynchronization Therapy Reduces Metaboreflex Contribution to the Ventilatory Response in Heart Failure Population

Table 2

Comparison of ventilatory data during rest and peak exercise with and without RCO before and 6 months after CRT. Values are given as means ± SEM. RCO, regional circulatory occlusion, RR, respiratory rate, VE, minute ventilation.

	Before CRT		After-6 month followup
	Normal	RCO	Normal	RCO
VE at rest (L/min)	12±3	13±4	12±3	13±2
Peak VE (L/min)	51±17	52±14	54±14	54±13
Peak VCO2 (L/min)	1.33±0.5	1.4±0.4	1.5±0.4	1.5±0.4
RR at rest (/min)	16±5	18±3	18±3	16±3
Peak RR (/min)	30±5	30±5	32±5	31±4
