LBBB with Prominent R Wave in V2
Report:Sinus rhythm First degree AV block PR interval 0.24â Left bundle branch block Comment:Prominent narrow R wave in V2, with subsequent diminution (through V5 in this example) is said to be a sign of old anterior infarction with LBBB. In my expe
LBBB in Cerebral Hæmorrhage
Report:Sinus rhythm SVEBs Left bundle branch block Primary T wave changes Comment:The patient was on Warfarin for intermittent AF in COCM (EF 30%); the INR was 3.9 at the time of the bleed. Old patients are at very high risk, perhaps due to cerebral a
Incomplete LBBB
Report:Sinus rhythm 94/min Incomplete LBBB Comment:The QRS is just over 0.10â long and, despite large voltages, there are no âseptalâ q waves in 1, aVL and V6. The last of these also shows delayed intrinsicoid deflection, but nobody looks at that
Alternating LBBB
Report:Sinus rhythm 87/min Alternating (2:1) left bundle branch block Small frontal plane voltage Nonspecific T wave changes Comment:The patient was admitted to CCU because of chest pain; a new LBBB developed. However, when disseminated carcinoma beca
LBBB with Northwest Axis
Report:Atrial fibrillation with ventricular response 98/min Left bundle branch block Axis approx. +240o Comment:The S wave in lead 1 makes the axis extreme right or left (no manâs land); this seems to have the same significance as right axis deviatio
Alternating LBBB with Right Axis Deviation
Report:Sinus rhythm 93/min Alternating complete & incomplete left bundle branch block Axis +95o with complete LBBB Indeterminate axis with incomplete LBBB Comment:The basic LBBB morphology is, as always, best seen in lead V1. In the limb leads, both c
Large Right Precordial R Waves in LBBB
Report:Sinus tachycardia 120/min Left atrial abnormality (LAA) Left bundle branch block Probable old anterior infarction Comment:The right precordial are waves look typically thin, like antennæ or unipolar pacing spikes. There is also a loss of R a
Bilateral Bundle Branch Block (BBBB)
Report: Sinus tachycardia 110/min Left atrial abnormality (LAA) Right axis deviation (RAD) +120o Probable left posterior hemiblock Right bundle branch block ST/T changes consistent with infarction/ischaemia Comment: Three years previously, this pati
Ventricular Fusion Beats
Report: Sinus rhythm First degree AV block PR 0.28â VEBs, possible parasystole Ventricular fusion beats Left bundle branch block QRS 0.20â Comment: The criteria for diagnosing ventricular fusion beats were formulated by Marriott et al18 in 1962
Bilateral Bundle Branch Block
Report:Sinus tachycardia 113/min Left anterior hemiblock Right bundle branch block Comment:This is only a bifascicular block â complete right and partial left bundle branch block. The term BBBB is not usually used for this. But if, as here, the patie
