Physiologic measurements observed at rest, peak exercise and minute three of recovery for paced patients and healthy controls

Data are expressed as mean values ± standard deviation. HR = heart rate, Q= cardiac output, O₂ Pulse = oxygen pulse, Vo₂ = oxygen uptake, Vco₂ = carbon dioxide production, SBP = systolic blood pressure, DBP = diastolic blood pressure and MAP = mean arterial pressure. †All variables decreased significantly (p < 0.05) from peak exercise to minute three of recovery except DBP. *Significantly different (p < 0.05) versus controls.
