Journal of Cardiovascular Electrophysiology; Lemke L, El Hamriti M et. al.

Oct 12th, 2022 - Atrioventricular (AV)-node ablation (AVNA) is a common therapy option for rate control strategy of permanent atrial fibrillation (AF). We hypothesized that isolation of the AV nodal isolation (AVNI) is associated with a more frequent preservation ...

A New Valve—and a Change of Heart?
https://www.mdedge.com/fedprac/article/211993/cardiology/new-valve-and-change-heart?channel=194
Lyle W. Larson, PhD, PA-C

Nov 11th, 2019 - ANSWER This ECG shows sinus rhythm with complete heart block and a junctional rhythm with a right-axis deviation. Additionally, ventricular depolarization in the precordial leads is suggestive of an anterior myocardial infarction.

Lyle W. Larson, PhD, PA-C

Sep 6th, 2017 - ANSWER The correct interpretation includes sinus rhythm with complete heart block and a junctional rhythm. Normal sinus rhythm is evidenced by normal-appearing P waves at a rate of about 66 beats/min, although there is some respiratory variation.
