The history of cardiac pacemakers: an electronics perspective

WebbThe pacemaker cells can also respond to various hormones that modulate heart rate to control blood pressure. There are two major types of cardiac muscle cells: myocardial contractile cells and myocardial conducting cells. The myocardial contractile cells constitute the bulk (99 percent) of the cells in the atria and ventricles. If the SA node does not function, or the impulse generated in the SA node is blocked before it travels down the electrical conduction system, a group of cells further down the heart will become its pacemaker. This center is typically represented by cells inside the atrioventricular node (AV node), which is an area between the atria and ventricles, within the atrial septum. If the AV node also fails, Purkinje fibers are occasionally capable of acting as the default or "escape" pacemaker. Webb21 juni 2015 · Chapter 34 Cardiac Pacing Modes and Terminology. Jose F.

The maximal tracking rate and the maximal sensor rate are to be programmed …

WebbIf no ventricular impulse is sensed, the pacemaker will pace at a pre-programmed rate (often 60 beats per minute [bpm] – VVI 60). If an electrical impulse is sensed, pacing is inhibited. DDD: commonly used for patients with AV nodal disease (eg complete heart block). Both the atrium and ventricle are sensed and paced.
