Dr. His was the first to recognize the bundle fibers. What is the function of the bundle of His and the Purkinje fibres? The bundle of His and the Purkinje fibers work as part of the electrical impulses in the heart to cause contractions. They work as a backup system to the heart's ...
When a cardiac impulse propagates from the A-V node to ventricular muscle, it must excite in temporal sequence: 1. the bundle of His; 2. the bundle branches; 3. the peripheral ramifications of the specialized intraventricular conducting system; 4. the terminal subendocardial Purkinje network;...
b. Bundle of His c. Sinoatrial node d. Atrioventricular node 4 19. The nurse is reviewing a normal electrocardiogram. The nurse assesses the PR interval because it represents: a. Atrial depolarization b. Ventricular depolarization c. Onset of atrial activation to onset of ventricular activity ...

Spinal cord injured men should therefore be assessed, to the same extent as palliative treatme' nts are offered, so that the individual is left with documented information about his remain ing function which may give him a sense of control over this intimate part of his life. ...
The electric current that causes the heart to beat runs through this area. Specifically, the AV node, also called the Aschoff-Tawara Node, is located near the top of the septum in the floor of the right atrium. It also contains the next stage of conduction through the Bundle of HIS. ...
The main elements of the excitatory and conductive components are the sinoatrial node (SAN), the internodal pathways, the atrioventricular node (AVN), the bundle of His and the Purkinje fibers6(Fig.1). This system is mainly composed of specialized CMs whose cytoarchitecture and electrophysiological...
Excitation spreads to the atrioventricular node, near the atrioventricular border, from which excitation is conducted by the bundle of His and the Purkinje system (groups of specialized muscle cells) to the bottom of the ventricles. Excitation spreads upward in the ventricles, contracting them from ...
The Heart Conduction System The conduction system of the heart refers to how the heart contracts. Here we explain how electrical impulses ensure it beats regularly including specific parts of the heart involved such as the Bundle of His, Synoartial node as well as exam-type questions and quiz...
Nick's utility function is U (x, y) = 33xy. He has 12 units of good x and 6 units of y. Boris's utility function for the same two goods is U (x,y)=2x 5y. Boris has 9 units of x and 13 units of y. A. Nick prefers Boris's bundle to his own bundle, but Boris ...
