| 摘 要： | 本文应用反符合电路剔除调搏脉冲干扰的方法,制成经食道心房调搏心电心音门电路触发装置,用于经食道心房调搏的核素心血管造影。参考Tzivoni标准,当逐级增加调搏心率至140次/min或亚极量心率后发现:冠心病人有调搏后EF降低;急性心肌梗塞病人EF减低更为明显,并呈室壁反向运动。因此,心房调搏核素心血管造影有助于冠心病,特别是心肌梗塞的诊断。

| Abstract: | By using an anticoincidence unit to cutoff the interference of pacing pulses, an EKG and phonocardiography (PCG) triggered gate circuit for atrial pacing per esophagus was made for RNA.According to the criteria of Tzivoni, when the pacing heart rate was increased by gradation to 140/min or subinaximal heart rate, it was found that in CAD patient there was a decreased EF value after pacing, and that in AMI patient decreased even lower and paradox movements of the ventricular wall was seen. Therefore, RNA by atrial pacing is useful for diagnosis of CAD, especially AMI. |
