单通道双探头超声心动图法评价慢型克山病心动周期的改变

EVALUATION OF THE CHRONIC KESHAN DISEASE IN CARDIAC CYCLE USING SINGLE-CHANNEL DUAL-SCANHEAD ECHOCARDIOGRAPHY

用 Arditti 单通道双探头法改进 M 型超声心动图仪,共检查慢型克山病41例,发现慢型克山病组的主动脉射血期、等容舒张期明显缩短,而等容收缩期则相对延长.而同步记录的 CPT,ECG,RCG 所测定的 PEP/LVET 比 ISP/AoET 大3.15倍,我们认为ISP/AoET 更为可靠.

Forty-two patients with chronic Keshan disease were examined using Arditti's improved single-channel dual-scanhead M mode echoeardiography.It was found that aortic ejection time(AoET)and isovolumic relaxation period(IRP)were shorter than that of the controls,however,isovelumic systolic period(ISP)was relatively lengthened. But PEP/LVET and ISP/AoET that were measured by synchronous CPT,PCG,ECG increased by 3.15. ISP/AoET was considered to be more reliable.
