Anterior Infarction, LBBB & Its Escape Rhythm
Report:Fig 89: Sinus rhythm 76/min Borderline LAA LVH with ST/T changes Anterior infarction ?age Fig 89a (24 hours later): Sinus rhythm 74/min Alternating complete & incomplete left bundle branch block Primary T wave changes Fig 89b (an hour late
Left Atrial Abnormality
Report: Sinus rhythm Left atrial abnormality First degree AV block PR 0.36â Normal axis Left bundle branch block QRS 0.125â Comment: The P waves are 0.12â (3 mm) long. Their P-terminal force (PTF) in lead V1 is well over 1 mm deep and 1 mm l
Post-LBBB T Wave Inversion
Report: Sinus rhythm Intermittent LBBB Widespread symmetrical T wave inversion Prolonged QT interval 0.60â Comment: This patient, with recurrent TIAs, could have post-syncopal T wave inversion. There was, however, no history of any âeventâ - cer
An Unusual Agonal Alternans
Report: Sinus bradycardia 46/min First degree AV block PR 0.64â Second degree AV block, 3:2 then 2:1 Left atrial abnormality Left bundle branch block QRS 0.42â T wave alternans Comment: The T wave is unaccountably flattened in alternate cycles
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
LBBB in Hyperkalæmia
Report: Accelerated junctional rhythm 90 - 96/min ? Sinus rhythm with sino-ventricular conduction Left bundle branch block QRS 0.22â Peaked T waves suggestive of hyperkalæmia Comment: The potassium rose to 8.0 mEq/L and probably higher. The rhyth
Left Axis Deviation in LBBB Conduction
Report:Sinus rhythm 72/min Borderline left atrial abnormality (LAA) Left bundle branch block Comment:In LBBB conduction the axis is derived from the entire QRS complex (unlike the situation with normal or RBBB conduction, where only the initial 0.06â
