本文报道34例过早搏动患者,男12例、女22例,平均年龄42.03岁。房性过早搏动7例、交界性过早搏动3例,室性过早搏动24例。服乙胺碘呋酮前后,分别用国产 XJY—6型心脏机能诊断仪检查所有患者。计算治疗前后每搏输出量(SV)、每分输出量(CO)、心脏指数(CI)、射血分数(EF)、短轴缩短率(△D%)。治疗后上述指标分别增加28.87±9.31%、24.66±11.27%、19.96±12.66%、28.78±13.22%、33.09±14.06%,有明显统计学差异。结果显示乙胺碘呋酮不抑制左心室机能,而稍加心搏量;用超声心动图研究左心室的功能是可取的。
This article reports 34 cases of premature beats, 12 males and 22 females, with an average age of 42.03 years. Atrial premature beat in 7 cases, 3 cases of borderline premature beats, ventricular premature beat in 24 cases. Before and after taking amiodarone, all patients were diagnosed with domestic XJY-6 cardiograph. The stroke volume (SV), output per minute (CO), cardiac index (CI), ejection fraction (EF) and short axis shortening (△ D%) were calculated before and after treatment. After treatment, the above indexes increased by 28.87 ± 9.31%, 24.66 ± 11.27%, 19.96 ± 12.66%, 28.78 ± 13.22% and 33.09 ± 14.06% respectively, with significant statistical difference. The results show that amiodarone does not inhibit left ventricular function, but a little stroke volume; echocardiography study of left ventricular function is desirable.
