巨R波综合征是以心电图出现巨大R波改变为突出征象的心电图综合征,临床少见但危急,表现为心脏缺血症状。主要疾病是冠心病,诱发原因可以是劳累、运动或应急情绪变化。发病机制是大面积急性心肌缺血早期的心肌损伤、局部传导阻滞等所造成的。如运动等诱因消除,心肌缺血改善,心电图可以恢复如常,如果心肌缺血进一步恶化,可以演变为急性心肌 Giant R wave syndrome is a large electrocardiogram R wave changes to prominent signs of ECG syndrome, clinical rare but critical, the performance of cardiac ischemia symptoms. The main disease is coronary heart disease, induced by fatigue, exercise or emergency mood changes. Pathogenesis is a large area of ​​acute myocardial ischemia in early myocardial injury, caused by local conduction block. Such as exercise and other incentives to eliminate, improve myocardial ischemia, electrocardiogram can return to normal, if myocardial ischemia further deteriorates, can evolve into acute myocardium
