Text: Maximal values for workload (108 + / - 46 W vs 117 + / - 48 W, p < 0. 01), oxygen uptake (Vo (2)) [21. 0 + / - 5. 3 mL/min/kg vs 22. 5 + / - 6. 4 mL/min/kg, p < 0. 05], oxygen pulse (13 + / - 3. 7 mL vs 14 + / - 4. 0 mL, p < 0. 05), and metabolic equivalent (6. 0 + / - 1. 5 vs 6. 4 + / - 1. 8, p < 0. 05) were significantly lower with permanent RV pacing compared to back-up pacing.
