网页2023年11月15日 · Complete Heart Block with Isorhythmic AV Dissociation (long rhythm strip): Atrial rate ~ 85 bpm; Ventricular rate ~ 42bpm; There is a junctional escape rhythm; As the ventricular rate is approximately half the atrial rate, this rhythm at first glance appears to be second-degree AV block with 2:1 conduction
EKG Interpretation & Heart Arrhythmias Cheat Sheet - Nurseslabs
网页2024年8月9日 · Use this EKG interpretation cheat sheet that summarizes all heart arrhythmias in an easy-to-understand fashion. One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart’s electrical activity as waveforms.
Heart Block Rhythms - ekg.academy
网页2021年11月8日 · Heart block rhythms occur when the cardiac electric impulse is delayed or blocked within the AV node, bundle of His or the Purkinje system. Heart block rhythms are classified into categories including these: First Degree Heart Block. Second Degree Heart Block Type II. Third Degree Heart Block. Bundle Branch Block. Heart Block Categories.
Overview of atrioventricular (AV) blocks – Cardiovascular …
网页Impulse conduction from the atria to the ventricles may be abnormally delayed or even blocked. These conditions are referred to as atrioventricular (AV) blocks, subdivided according to the degree of block. First-, second- and third-degree AV block may all be diagnosed using the ECG.
Second-degree AV block: Mobitz type 1 (Wenckebach)
网页Mobitz type 1 block is characterized by a gradual prolongation of the PR interval over a few heart cycles until an atrial impulse is completely blocked, which manifests on the ECG as a P-wave not followed by a QRS complex. This cycle repeats itself over and over again, such that every cycle ends with a blocked P-wave.

ECG Rhythm Evaluation • LITFL • ECG Library Basics
网页6 天之前 · The rhythm is best analyzed by looking at a rhythm strip. On a 12 lead ECG this is usually a 10 second recording from Lead II. Confirm or corroborate any findings in this lead by checking the other leads. A longer rhythm strip, recorded perhaps recorded at a slower speed, may be helpful.
ECG Basics: Third-degree AV Block, Complete Heart Block
网页2015年11月18日 · This rhythm strip shows third-degree AV block, also called complete heart block or complete AV block. The P waves are from the sinus node, and are regular at a rate of about 120/min. (Sinus tachycardia). This is a good strip for showing your students how to "march out" the P waves to find the ones that are hidden behind QRS complexes …
