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
Bigeminy or Quadrigeminy?
Report: Sinus rhythm approx. 54/min First degree AV block, variable VEBs, bigeminal Concealed retrograde conduction Pacemaker escape beats Comment: This is an allorhythmia, a repetitive sequence of (in this case) four beats. The VEBs themselves are,
Northwest Axis of Ventricular Tachycardia
Report: Ventricular tachycardia 167/min Comment: The diagnosis of VT rests on monophasic R wave in V1, rS in V6 and the bizarre, âNorthwestâ axis in the limb leads. In V1 there is a soupçon of rabbit ears, with the left one taller than the right. I
