Impulse conduction pathway
Key Points_Cardio 7 - Ohio University
In light of the fact that reentry involves conduction around a non-conducting area or core, it is easy to understand how the presence of an accessory pathway could lead to reentry; the most common reentry tachycardia with an accessory pathway is called orthodromic AV reentry; in this case, the SA node’s impulse follows the regular pathway ...

Impulse generated high up the conduction system (around the area of the His bundle or AV junction) will produce a narrow QRS with a faster escape heart rate and generally better tolerated by patients. Those generated further down (from the ventricular myocardium and Purkinje system) will more likely produce a broader complex with slower ...

Page 4. Pathway of Depolarization. SA Node • Located in upper right atrium. • Initiates the depolarization impulse which, in turn, generates an action potential that spreads throughout the atria to the AV node. • Sets the overall pace of the heartbeat. Internodal Pathway • Located in the walls of the atria. • Links the SA node to the ...

Conduction of nerve impulses. A, In an unmyelinated fiber, a nerve impulse (action potential) is a self-propagating wave of electrical disturbance. B, In a myelinated fiber, the action potential “jumps” around the insulating myelin in a rapid type of conduction called saltatory conduction. Slide 18. Patellar reflex.
