Normal pri interval - Study guides, Class notes & Summaries

Know how to measure the PR interval ( PRI)Know how to measure the QRSKnow the normal values for the PRI and the QRS Know what electrical activity triggers which mechanical event. For example what electrical event represents atrial contraction? Know the blood circulation through the heart, starting from the superior vena cava and progressing through the right side of the heart, the lungs and the left side, ending up finally going through the aortic valve and into the aorta. Know the electrical co...

EKG STUDY MATERIAL FOR ADVENTHEALTH Exam Questions With Verified Answers 3 pacemakers of the heart - answer1. SA node 2. AV node 3. bundle branch intrinsic rate of SA node - answer60-100 bpm intrinsic rate of AV node - answer40-60 bpm intrinsic rate of bundle branches - answer20-40 bpm electrical pathway through the heart - answer1. normal conduction impulse originates in the *SA Node* 2. impulse travels to *AV Node* causing atrial depolarization (contraction) 3. AV Node slightly del...

Normal PRI interval - correct answer0.12-0.20 Normal QRS interval - correct answer0.11 or less What does the P wave represent? - correct answerAtrial depolarization What does the QRS complex represent? - correct answerAtrial repolarization and ventricular depolarization Q wave indicates what? - correct answerDead myocardial tissue. Always a negative deflection What is the natural pacemaker of the heart? - correct answerSA node 3 types of pacemakers - correct answer1) single (ei...

First Degree Atrioventricular Heart Block - ANS prolonged PR interval-measures the time required for an impulse to travel from the SA to the AV node. PRI longer than 0.20 Second degree AV block Type I - ANS progressive prolongation of PRI, gradual shortening of R to R intervals P wave not followed by a QRS wave a pause with an R to R interval less than the sum of two P to P intervals first conducted atrial impulse after the pause shows a shorter or normal PRI S...

Normal Conduction System -ANSWER -SA Node = Primary Pacemaker of the Heart, rate of 60-100 bpm -Internodal Pathways = Pathways connecting SA Node and AV Node -AV Node = Backup pacemaker, rate of 40-60 bpm -Bundle of His = splits nerve fibers down Left & Right Sides, His-Purkinje is conduction system of heart -L & R Bundle Brancehs = lead to left & right of the myocardium -Purkinje Fibers / Network = ends of the muscle, last escape pacemaker sites rate of 14-40 Tele Strip Paper -ANSWER ...
