These cells carry electrical energy through the heart in a predictable pattern, stimulating the different parts of the heart to contract in a regular rhythm. This network is called the intrinsic cardiac conduction system. Answer and Expla...

Answer to: The "pacemaker" of the heart is the A. SA node. B. AV node. C. AV septum. D. ventricle. By signing up, you'll get thousands of...
The SA node responds to the body's overall need for blood and increases the heart rate when necessary, such as during exercise, emotional excitement, or illness such as fever. The SA node is sometimes called the “natural pacemaker” of the heart. ●Electrical impulses leave the SA node ...
PURPOSE: To provide a cardiac pacemaker having desired features such as physiological responsiveness, quick responsiveness, long-time reliability and high-grade limitedness by sensing blood pressure and controlling the frequency of heartbeats corresponding to this blood pressure. CONSTITUTION: A pulse ...
Transistorized Pacemaker for Remote Stimulation of the Heart by Radio-Frequency Transmission Diverse techniques have been developed for controlling the cardiac rate by external means when normal physiological processes fail to maintain a stable rat...

They act also to conduct impulses throughout the heart, in a rapid and coordinated fashion1. The main components of the cardiac conduction system are the sinus node of the right atrium, which is the primary pacemaker; the atrioventricular conduction axis, which normally forms the only pathway ...
The natural pacemaker of the heart is made of cardiac muscle tissue that stimulates other cardiac muscle cells to contract. Because of its self-stimulation, cardiac muscle is considered to be autorhythmic or intrinsically controlled. The cells of cardiac muscle tissue are striated---that is, they...
Define Heart pacemaker. Heart pacemaker synonyms, Heart pacemaker pronunciation, Heart pacemaker translation, English dictionary definition of Heart pacemaker. Noun 1. artificial pacemaker - an implanted electronic device that takes over the function of
Finally, the bundle at the end of the bundle branch is divided into millions of Purkinje fibers. Nowadays, many researchers have begun to study electrophysiology by including various conduction cells. The sinoatrial node is the normal pacemaker of the mammalian heart. There are a few mathematical ...
