It's the ECG's that george rejects that makes George's ECG's the best.
Escape-Capture Bigeminy in AF
Report: Atrial fibrillation High-grade or complete AV block Junctional rhythm 39/min Pacemaker (escape) rhythm Escape-capture bigeminy Left anterior hemiblock (LAHB) Right bundle branch block Anteroseptal infarction, age uncertain ST/T changes con
Pacemaker: Escape-Capture Bigeminy
Report:Sinus tachycardia 100/min First degree AV block (PR 0.28") Second degree AV block. Right bundle branch block Pacemaker (escape) beats Escape-capture bigeminy Comment:Before Bradley and Marriott's classical description6, this rhythm was call
Atrial Fusion Beats
Report:Sinus rhythm Junctional ? atrial rhythm Shifting (atrial) pacemaker Atrial fusion beats AV dissociation Probable third degree AV block Pacemaker rhythm 63/min Comment:Again, this is a "trick" question, designed to make one look (in vain) f
Complete AV Block
Report:Third degree AV block Sinus bradycardia 42/min Junctional beats (top strip) Atrial fibrillation Junctional escape rhythm 36/min Pacemaker rhythm 82/min Short QT interval ? digoxin toxicity Comment:The varied atrial activity has no effect on
Failed Pacemaker?
Report: Sinus tachycardia 104 - 124/min First degree AV block[!xe "PR interval:long" \t "See AV block, first degree"!] Second degree AV block, probably Möbitz 2 Third degree AV block Ventricular standstill Junctional escape rhythm, ventricular esca
Skipped P Waves in Wenckebach Conduction
Report: Sinus tachycardia 120-128/min First degree AV block Second degree AV block, Möbitz 1 Periods of 3:2 conduction, with bigeminy Right bundle branch block Pacemaker rhythm 72/min Fusion and pseudofusion beats Comment: The key to correct interp
Iatrogenic Ventricular Standstill
Report: Sinus rhythm 100/min Ventricular standstill (asystole) Comment: Hereby hangs a tale: The ECG technician ran to my (reporting) room in New York pale and trembling, clutching this trace in obvious fear. A senior Cardiologist saw her taking th
Two Rhythms of Indubitably Ventricular Origin
Report: Pacemaker rhythm VEBs Ventricular fibrillation CPR artefact (end of bottom strip) Comment: It has been said (the actual reference eludes me) that the only two rhythms of electrocardiographically certain ventricular origin are ventricular fib
Atrial Pacing & Intercalated VEBs
Report: Atrial pacemaker rhythm VEBs, intercalated (interpolated) Comment: The VEBs show the diagnostically important left rabbit ear and different initial vector from the paced beats. They also prolong the subsequent A-R intervals through concealed ret
Accelerated Idioventricular Rhythm in Complete AV Block
Report: Sinus tachycardia 120/min Accelerated idioventricular rhythm 65/min Third degree AV block Comment: One can confidently diagnose complete AV block when the atrial rate is so much faster than the ventricular, without any captures, the ventricular
