The heart exhibits ___ (beats in coordinated fashion)- initiates its own heartbeat. SA( sinoatrial), AV (atrioventricular), HIS, purkinje The steps of a conducting system of the heart is:1. Electrical signal will begin at the ___ node (hearts pacemaker)2. Impulses from the SA node will...
The "pacemaker" of the heart is the A. SA node. B. AV node. C. AV septum. D. ventricle. Blood Flow in the Heart: The heart is the major organ of the cardiovascular system and receives and delivers blood to and from all parts of the body. All deo...
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...

The normal heart rhythm, known as sinus rhythm, originates in specialized cardiac cells, called pacemaker cells, in the sino-atrial (SA) or sinus node and has been defined as a sinus node rate of 60 to 100 beats/minute. Each heart beat or contraction is initiated by generation of an ...
In a statement online the Ministry of Health said, "The National Centre for Cardiac Surgery at the Royal Hospital used a heart pacemaker called the 'leadless pacemaker' for the first time in Oman." Royal Hospital implants Oman's first leadless pacemaker "His sphere of influence spanned across...

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 ...
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 heart 4.(Medicine) Also called:artificial pacemakeran electronic device for use in certain cases...
The heart pumps blood with a rhythm determined by a group of pacemaker cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node and along the conduction system of the heart. The heart receives blood low in oxygen ...
