Möbitz 2 Block
Report: Sinus rhythm First degree AV block PR 0.22â Second degree AV block, Möbitz 2 Left posterior hemiblock Right bundle branch block Comment: The fixity of the PR interval rules out Möbitz 1 (Wenckebach) mechanism for the AV block. Almost inv
Möbitz 2 AV Block & Right Bundle Branch Block
Report:Sinus rhythm 90/min Second degree AV block, Möbitz 2 Right bundle branch block Borderline left atrial abnormality (LAA) Comment:All the PR intervals, before and after the block, are 0.16â. This is type 2 block, intraventricular: the LBB is b
Complete AV Block in Shock
Report:Atrial flutter 375/min Complete (3rd degree) AV block Junctional rhythm 65/min Right axis deviation +90o ?LPHB Right bundle branch block Acute inferior and anteroseptal infarction Leads V3-6 probably right-sided: right ventricular infarction
Fascicular Ventricular Tachycardia & Positive Concordant Precordial Pattern
Report:Ventricular tachycardia 198/min Comment:Fascicular ventricular tachycardia12,13 is distinguished by the relatively narrow QRS width and marked axis deviation in the frontal plane; in this case the QRS lasts just under 0.12â, less than in sinus r
Ventricular Tachycardia : Narrower QRS in VT
Report: Top: Sinus arrhythmia Borderline first degree AV block VEBs Rate-dependent right bundle branch block Bottom: Sinus rhythm Right bundle branch block Ventricular tachycardia 148/min AV dissociation Comment: The tachycardia in the bottom st
Precordial Masquerading Bundle Branch Block
Report :Atrial fibrillation with rapid ventricular response 138/min Northwest axis +260o Right bundle branch block (Probable) left anterior hemiblock Possible old anterior myocardial infarction Nonspecific ST/T changes Positive concordant precordia
The Frailty of Lead 2 Monitoring
Report:Sinus rhythm 78/min VEBs in bigeminy Right bundle branch block Small voltage Possible old anterior infarction Comment:Leads V1-5 clearly distinguish between the ectopic ventricular and the sinus RBBB conduction. Lead 2 performs, as usual, badl
VEBs: Long Compensatory Pauses
Report:Sinus rhythm 97/min VEBs Right bundle branch block Probable old inferior infarction Comment:The pauses containing the VEBs are obviously longer than two sinus cycles. This admits only one explanation â the VEBs have been conducted retrogradel
AV Dissociation in VT
Report: Sinus tachycardia 127/min Left atrial abnormality (LAA) First degree AV block (PR 0.22â) Axis -100o (Northwest, no-manâs land, ânonsenseâ axis) Probable left anterior hemiblock Right bundle branch block VEB, probably fusion beat (5th
SVT: Pre-existing RBBB/LAHB
Report: Tachycardia 102/min ? origin Onset of supraventricular tachycardia 190/min Right bundle branch block Left anterior hemiblock Anterior infarction, probably old Comment: Frontal plane axis of â90o and the monophasic R wave in V1 bode ill for
