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
Intraventricular Conduction Delay (IVCD)
Report:Sinus rhythm 60/min Intraventricular conduction delay (defect, IVCD) Diffuse nonspecific ST/T changes Prominent U wave Comment:Characteristically, the patientâs potassium fell from 3.5 to 1.8 mEq/L following absorption of hydroxychloroquine;
Lown-Ganong-Levine Syndrome
Report:Sinus rhythm 65/min LGL conduction PR interval 0.10â Borderline inferior T wave changes Comment:The commonly accepted explanation for the short PR interval is partial or complete AV nodal bypass by paranodal fibres inserting into the bundle o
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
Left Anterior Hemiblock Aberrancy
Report:Sinus rhythm Normal axis +70o Allorhythmic triplets of SVT following single sinus beats First complex LAHB aberrant â40o Comment:The SVT triplets are separated by a single sinus beat â a minimalist (three-beat) form of repetitive atrial tac
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
Fusion Beats in Idioventricular Escape Rhythm
Report:Sinus bradycardia 27/min First degree AV block Right bundle branch block (by inference) Right bundle branch escape rhythm 28/min Fusion beats Comment:As the PR interval shortens the QRS gets fatter. This means that the P waves are conducted. T
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
