This case refers to a 39-year-old woman with hypertrophic cardiomyopathy (HCM) and family history of sudden death (SD). In 1985, high rate atrial stimulation induced VF. In 1996 an ICD was implanted and she remained without arrhythmic events until November 2000 when the device reported one episode of atrial fibrillation degenerating into VF and terminated by the ICD. The VF induction mechanism recorded by the ICD was similar to that observed in 1985. The high incidence of atrial tachyarrhythmias in HCM renders cases like this at higher risk of SD. The predictive role of incremental atrial stimulation merits highlighting in future studies.
该病例为一名39岁患有肥厚型心肌病（HCM）且有猝死（SD）家族史的女性。1985年，高频率心房刺激诱发室颤。1996年植入了植入式心律转复除颤器（ICD），此后她一直未发生心律失常事件，直到2000年11月，该装置记录到一次房颤恶化为室颤的发作，并由ICD终止。ICD记录的室颤诱发机制与1985年观察到的相似。肥厚型心肌病中心房快速性心律失常的高发生率使此类病例发生猝死的风险更高。递增性心房刺激的预测作用值得在未来研究中加以强调。
