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 Expl...
2.a person, an organization, etc, regarded as being the leader in a particular field of activity 3.(Anatomy) Also called:cardiac pacemakera small area of specialized tissue within the wall of the right atrium of the heart whose spontaneous electrical activity initiates and controls the beat 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. ...
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...
1) The pacemaker rhythm that determines heart rate is called ___ rhythm. sinus 2) The ECG ___ wave interval represents ventricular repolarization. T 3) The ___ layer of the serous pericardium covers the heart. visceral 4) The ___ valve of the heart has three valves with chordae tendin...

The sinoatrial (SA) nodes are areas of the heart's atrium that act as the heart's pacemaker. Impulses from the SA node cause the heart’s chambers to contract. Purkinje fibers receive their impulses from the SA node and move the impulse through the heart’s muscles. Just below the atrium...
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 ...
