双相电刺激心脏疗法是利用交替阀值脉冲对心肌的作用,使收缩频率变慢。给心脏以人工节律,恢复心脏固有的节律。缩短收缩频率是以心肌的生理特点为基础,把心肌的收缩功能恢复到原来的水平(每次0.1秒)。脉冲刺激心脏,一则可引起心脏的完全收缩,二则可引起心脏的兴奋(与血液动力学无关的期外收缩),当大量的脉冲输入
Biphasic electrical stimulation of cardiac therapy is the use of alternating threshold pulse on the role of the heart, so that the frequency of contraction of the slow. To the heart with artificial rhythm, restore the heart’s inherent rhythm. Shorten the frequency of contraction is based on the physiological characteristics of the myocardium, the systolic function of the heart to restore the original level (0.1 seconds each time). Pulsed stimulation of the heart, one can cause complete contraction of the heart, the second can cause heart excitement (non-hemodynamic hemodynamic contraction), when a large number of pulse input
