Right coronary artery occlusion can lead to failure to capture from the right atrial pacing lead. In this case, acute infarction resulted in failure of the right atrial lead to capture and thus increased right ventricular pacing. The new ventricular pacing masked the diagnosis of acute myocardial infarction. ().
右冠状动脉闭塞可导致右心房起搏导线夺获失败。在这种情况下，急性梗死导致右心房导线夺获失败，从而增加了右心室起搏。新的心室起搏掩盖了急性心肌梗死的诊断。（）
