The mechanisms of sinoatrial node (SAN) dysfunction in heart failure (HF) remain unclear. We hypothesized that impaired rhythmic spontaneous sarcoplasmic reticulum Ca(2+) release (Ca(2+) clock) plays an important role in SAN dysfunction in HF. HF was induced in canine hearts by rapid ventricular pacing. The location of pacemaking sites was ...
