As shown in Fig. 3, it differs from the action potential of cardiac myocytes in that phases 1 and 2 are absent. The heart displays autorhythmicity: a denervated heart (such as the heart of a cardiac transplant patient) continues to contract spontaneously.

WebElectrical Conduction System of the Heart. The human heart is an engine that has to work 24/7 to keep you alive, and it has to be reliable and effective. To do this, it relies on a specialized network of cells that conduct electricity to the different parts of your heart. This network is the heart’s electrical system. 800.659.7822. WebMost pacemakers are demand pacemakers. This means that they only pace on demand (e.g. when the heart rate is less than 60). To achieve this, the pacemaker has two functions: pace or inhibit. Let’s take a pacemaker with a single ventricular lead and run through a cardiac cycle: A ventricular contraction is sensed by the pacemaker. This begins ...
Web2) Pacemakers can't be used for tachycardia, because even with the refractory periods for the cardiac action potentials the heart will keep beating faster anyway. There's also some risk that the pacemaker could fire at the wrong part … WebThe base rate is the lowest heart rate allowed by the pacemaker; intrinsic cardiac activity below the base rate will trigger pacing. The base rate is …
