ECG interpretation Correct Answer-(understand/know) ECG - rate calculation Correct Answer-(understand/know) P waves Correct Answer-represents time for atrial depolarization (contraction); should be upright; 0.06-0.12; disturbance indicates conduction problem within atria QRS interval Correct Answer-measured from beginning to end of QRS complex; represents time for ventricular depolarization (contraction); <0.12; disturbance indicates conduction problem in bundle branches or ventricle...

Advent Health EKG Questions and Answers Rated A Afib The impulse originates in the Atria • The Atrial rate is > 300 and unable to measure [N/A] • No discernable P waves - PRI & Atrial rhythm cannot be measured [N/A] • The Ventricular rhythm is irregular • QRS within normal limits • If the Ventricular rate is <100 the rhythm is controlled A-fib; if the Ventricular rate is > 100 the rhythm is uncontrolled A-fib • This is a chronic rhythm for some patients Treatment: controlle...

What period follows depolarization of the myocardium and represents a period during which no new cardiac potential can be propagated? Correct! Refractory Threshold Sinoatrial (SA) Hyperpolarization During the refractory period, no new cardiac action potential can be initiated by a stimulus. This selection is the only option that accurately identifies the period described in the question. Question 2 2 / 2 pts What is the suggested mean blood pressure for an 8- to 9-year-old ch...
