起搏器和埋藏式心脏转复除颤器(ICD)不断进展,例如更接近生理的起搏器、具有诊断功能(心力衰竭),远程调控(无线),采用其他能源的起搏器等。人心脏具有很大的储备,能够增加心率和增加收缩力相当长一段时间而不影响心脏功能。作者试图收获心脏收缩动作用作起搏器能源。方法用导管 Pacemakers and implantable cardioverter defibrillators (ICDs) continue to evolve, such as physiologically paced pacemakers, diagnostics (heart failure), remote control (wireless), pacemakers using other sources of energy, and more. The human heart has a large reserve, can increase the heart rate and increase the contractility for a long period of time without affecting the heart function. The author attempted to harvest cardiac contractility as pacemaker energy. Method with catheter
