无创性方法测定收缩时间问期(STI),借以评定心脏功能已在国内外广泛开展。但由于测定STI需同步记录心电图(ECG)、心音图(PCG)及颈动脉搏动图(CPT),需拥有多导记录仪方能开展此项工作。由于高质量的多导
Noninvasive methods to measure the time to systolic (STI), in order to assess cardiac function has been widely carried out at home and abroad. However, due to the STI need to simultaneously record ECG, phonocardiogram (PCG) and carotid artery pulsation diagram (CPT), need to have a multi-guided recorder can do this work. Due to the high quality of multi-guide
