Atrial Sensing and Pacing
Report:Sinus rhythm 75/min 1 VEB 1 Atrial-sensing ventricular pacemaker 3 Atrial sensing and pacing ventricular pacemaker (last beat) 4 Left atrial abnormality (LAA) 1 Comment:This is a DDD pacemaker, responding to both the atrial activity and the la
Acute Infarction with Pre-existing LBBB
Report:Sinus rhythm 60/min Left atrial abnormality (LAA) Left bundle branch block Acute inferior & anterior infarction Comment:The diagnosis was based on new and marked ST segment elevation in the inferior leads and V3 as well as concordant T inversio
Anterior Infarction and Rate-Dependent LBBB
Report:Sinus rhythm 66/min SVEBs, blocked Rate-dependent left bundle branch block Anterior infarction ?age Comment:The pauses created by the non-conducted SVEBs are long, but still not fully compensatory. The complexes terminating the pauses are norma
Inferolateral Infarction & LBBB
Report:Sinus rhythm 88/min Left bundle branch block Acute inferolateral infarction Comment:Unlike the previous caseâs IVCD, this one shows typical LBBB, with sharp S descent and slower ascent in V1. Despite this, there is a concordant ST segment elev
LBBB & Hyperkalæmia
Report: Junctional rhythm 57/min VEBs Left axis deviation Left bundle branch block Tall T waves consistent with hyperkalæmia Comment: The QRS narrowed to a left anterior hemiblock and the T waves normalised as potassium level came under control (Fig
LBBB: Old Myocardial Infarction
Report:Sinus rhythm 64/min Third degree AV block Junctional escape rhythm 36/min Left bundle branch block QRS 0.22â Probable old anterior infarction Comment:The patient had LBBB since his original infarction; the present morphology is identical t
Incongruous BBBB
Report: Sinus rhythm 84 â 88/min Advanced second degree AV block 3:1 & 4:1 AV block Right bundle branch block PR interval 0.32â Left bundle branch block PR interval 0.20â Comment: This is quite rare. The two bundle branch blocks have differen
LBBB: Negative Concordant Precordial Pattern
Report: Sinus rhythm PR interval 0.20â Left atrial abnormality Normal axis Left bundle branch block Comment: History of infarction and marked cardiomegaly are clues as to why there is a concordant precordial QS pattern. This example has normal axis
Phasic Aberrant Conduction in AF: Ashmanâs Phenomenon
Report:Atrial fibrillation with ventricular response 108/min Ashmanâs phenomenon Nonspecific inferior T wave changes Comment:The chest discomfort could be ascribed to AF. In 1947 Gouaux and Ashman published a report of RBBB aberration mimicking VT d
Atypical LBBB: Anterolateral Q Waves
Report: Sinus rhythm SVEBs, runs of SVT Left axis deviation â50o Intraventricular conduction delay, probably atypical left bundle branch block Probable old anterior infarction ST/T changes suggest infarction/ischæmia. Comment: Post-arrest ECGs (a
