A 74 year old patient with cardiac resynchronization therapy (CRT) since 12 months presents with cardiac decompensation and dyspnea NYHA III-IV after improvement of cardiac symptoms for 9 months. Her history is remarkable for left ventricular hypertrophy, aortic valve replacement 14 years earlier, a left ventricular ejection fraction of 35-40%, and permanent third degree AV block. The 12 lead standard ECG reveals the cause of cardiac deterioration which is confirmed by telemetry. This case demonstrates the importance of optimized programming of CRT systems which differs from conventional programming of dual-chamber devices in some aspects.
一名接受心脏再同步治疗（CRT）12个月的74岁患者，在心脏症状改善9个月后出现心脏失代偿和纽约心脏协会（NYHA）心功能III - IV级的呼吸困难。她有左心室肥厚病史，14年前接受过主动脉瓣置换术，左心室射血分数为35 - 40%，存在永久性三度房室传导阻滞。12导联标准心电图揭示了心脏恶化的原因，遥测证实了这一点。该病例表明了优化CRT系统程控的重要性，这在某些方面与双腔设备的传统程控有所不同。
