美国弗明翰医院一项长达26年的随访资料显示,在不伴器质性心脏病的心房颤动(房颤)人群中,房颤可增加3倍心室颤动(室颤)的发生风险,患者的死亡率是正常人的2~4倍,并有可能发生猝死。有学者因此提出了“房颤-室颤-猝死”这一新的疾病链~[1]。ICD资料证实,需要ICD资料的恶性心律失常中,18%的室颤和3%的室性心动过速(室速)的上游心律为房颤~[2],而在需要植入ICD治疗 A 26-year follow-up at the Framingham Hospital in the United States shows that atrial fibrillation increases the risk of ventricular fibrillation (VF) three times greater in patients with atrial fibrillation (AF) without organic heart disease, The patient’s mortality rate is 2 to 4 times normal, and there is a risk of sudden death. Some scholars therefore proposed “atrial fibrillation - ventricular fibrillation - sudden death ” this new disease chain ~ [1]. ICD data confirm that 18% of ventricular fibrillation and 3% of ventricular tachycardia (VT) have atrial arrhythmia in patients with ICD-requiring malignant arrhythmias, [2] and in patients who require ICD implantation
