Figure 1A-B. Changes of cardiac depolarization-repolarization interval after ingestion of capsaicin tablets (CAP) or placebo tablets (CON) randomly at rest and during exercise in healthy young men. There were not significantly differences on cardiac depolarization-repolarization interval at rest and during exercise in capsaicin and placebo trials at any point. a RTc corrected activation recovery interval, b QTc corrected QT interval. Values represent means ± SE.
