The Cardiovascular System

constitutional Conduction System1. The integral conduction placement consists of __autorhythmic cardiac______ cells that initiate and distribute __impulses___ throughout the center of attention.2. The intrinsic conduction placement coordinates heart fill mechanism by determining the direction and fixture of _heart depolarization___. This leads to a coordinated heart contraction.3. advert the functions for the following parts of the intrinsic conduction system a. SA Node __initiates the depolarizing impulse and sets the yard for the entire beat___ b. Internodal Pathway __link between the SA invitee and the AV node__ c. AV Node __delay occurs allowing atria to contract___ d. AV Bundle (Bundle of His) _link between atria and ventricles__ e. Bundle Branches __convey impulses consume the interventricular septum___ f. Purkinje Fibers ___convey the depolarization throughout the ventricular walls_____4. The action potentials spread from the autorhythmic cells of the intrinsic co nduction system (electrical event) to the _contractile__ cells. The resulting mechanical events cause a heartbeat.5. A tracing of the electrical activity of the heart is called a/an __electrocardiogram__.6. What do the following fluctuate forms reflect? . P ripple ___atrial depolarization___ b. QRS mixed ___ventricular depolarization____ c. T wave __ventricular repolarization___7. In a normal ECG wave tracing, atrial repolarization is hidden by __QRS Complez__.8. Note galvanizing events lead to mechanical events. For example, the P wave represents __atrial_ depolarization, which leads to atrial _contraction___.9. A left atomic reactor branch block would have a wider than normal wave for the __QRS complex_. (Quiz section) 10. An abnormally dissipated heart rate (over 100 beatniks per minute) is called __tachycardia___. (Quiz section)
