History of Defibrillation.. One of the first descriptions of ventricular fibrillation and its link to sudden cardiac death belongs to the British physiologist John A. McWilliam, a former student of the famous Carl Ludwig, who was working at the University of Aberdeen. He wrote in the late 1880s. that ventricular fibrillatio作者: Obedient 時(shí)間: 2025-3-22 01:46 作者: Dictation 時(shí)間: 2025-3-22 06:23 作者: 去世 時(shí)間: 2025-3-22 09:08 作者: 百靈鳥(niǎo) 時(shí)間: 2025-3-22 15:00

When electrodes are physically placed on the myocardium, not only do they induce polarization changes in the cell membrane in regions in proximity to the electrodes, but they also induce polarization changes remote to the electrodes.

Critical Points and the Upper Limit of Vulnerability for Defibrillationne. Except for very large shocks that are so strong that their damaging effects cause immediate refibrillation, there is a range of shock strengths, below which shocks almost always fail to defibrillate and above which they usually successfully defibrillate. Throughout this range, the probability of作者: COWER 時(shí)間: 2025-3-23 01:54 作者: 切掉 時(shí)間: 2025-3-23 09:13
