【摘要】 目的分析心脏淀粉样变(cardiac amyloidosis,CA)患者临床心电图的特征。方法回顾性分析在我院明确诊断的45例CA患者的临床心电图特征。结果 45例患者的心电图表现中,快速性心律失常包括偶发性房性早搏(19例,42.22%)、房性心动过速(16例,35.56%)、房颤(14例,31.11%)、偶发性室性早搏(12例,26.67%)、频发室性早搏(8例,17.78%)、非持续性室速(6例,13.33%);缓慢性心律失常包括窦性心动过缓(11例,24.44%)、> 2.0 s窦性停搏(3例,6.67%)、一度房室传导阻滞(8例,17.78%)、二度房室传导阻滞(2例,4.44%)、室性逸搏心律(2例,4.44%)、较严重的心室停搏(1例,2.22%)且最长停搏时限6.16 s;其他表现为QRS低电压、假性梗死波形、ST-T改变、束支传导阻滞等。结论心电图检查操作简单方便、可行性高,有助于CA的早期诊断。更多还原

【Abstract】 Objective To analyze the characteristics of clinical ECGs of patients with cardiac amyloidosis( CA). Methods Retrospective analysis was carried out on the characteristics of clinical ECGs of 45 CA patients definitely diagnosed in our hospital. Results Among the ECG manifestations of 45 cases,tachyarrhythmias include occasional atrial premature beats( 19 cases,42. 22%),atrial tachycardia( 16 cases,35. 56%),atrial fibrillation( 14 cases,31. 11%),occasional premature ventricular contraction( 12 cases,26. 67%),frequent premature ventricular contraction( 8 cases,17. 78%),nonsustained ventricular tachycardia( 6 cases,13. 33%);slow arrhythmias include sinus bradycardia( 11 cases,24. 44%),sinus arrest over 2. 0 s( 3 cases,6. 67%),first-degree atrioventricular block( 8 cases,17. 78%),second-degree atrioventricular block( 2 cases,4. 44%),ventricular escape rhythm( 2 cases,4. 44%),severe ventricular arrest( 1 case,2. 22%) with the longest arrest duration of 6. 16 s; other ECG manifestations are QRS low voltage,waveform of false infarction,ST-T changes,bundle branch block and so on. Conclusion ECG examination is easy and convenient to be operated with high feasibility. It is helpful in the early diagnosis of CA.更多还原
