Stroke Volume: A Hemodynamic Variable for Rate-Adaptive Pacingombination of these three mechanisms was effective enough in the majority of patients to mask the clinical need for a rate increase. However, since both the stroke volume and the percentage of oxygen which can be extracted from the blood are limited physiologically, there is always a loss of cardiac reserve in fixed-rate pacing.作者: Notify 時(shí)間: 2025-3-27 14:47
Hemodynamics of the Paced HeartThe hemodynamics of the pacemaker patient is subject not only to the general determinants of cardiac function, such as contractility of the myocardium, preload and afterload, but also to specific factors resulting from the nature of the patient’s conduction defect and/or the particular pacing mode applied.作者: anthesis 時(shí)間: 2025-3-27 19:24 作者: 提名 時(shí)間: 2025-3-27 23:36 作者: trigger 時(shí)間: 2025-3-28 04:03 作者: Insubordinate 時(shí)間: 2025-3-28 09:34
