心肌供血不足

结论：老年人在心肌供血不足的基础上发生室上性心动过速同室性心动过速有同等重要的意义目的：探讨老年人在EKG示心肌供血不足时发生室上性心动过速的意义。

Conclusion SVT was as important meaning as ventricular tachycardia for the old with myocardia ischemia . Objective To explore the significance of EKG showing supraventricular tachycardia ( SVT ) of the old caused by myocardia ischemia .

Conclusion The postoperative death is affected by relatively serious respiratory disease , myocardial ischemia , and serious renal failure .
