Thyrotoxicosis
Report:Supraventricular tachycardia 215/min Comment:Somewhat unusual first presentation of thyrotoxicosis; not even spectacularly fast. However, following adenosine-induced reversion to sinus rhythm, she remained quite tachycardic (Fig 94a) and thyroid f
P congenitale: Tetralogy of Fallot
Report:Sinus rhythm First degree AV block PR 0.24â Right atrial abnormality P congenitale (P axis +60o) Right axis deviation +125o Right bundle branch block Right ventricular hypertrophy Comment:In P congenitale the atrial wave is quite large
Endocardial Cushion Defect
Report:Sinus rhythm Borderline left atrial abnormality First degree AV block PR 0.26â Left axis deviation â 90o Right ventricular hypertrophy Possible left ventricular (â´biventricular) hypertrophy Comment:This is another RVH, but with an LAD
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
RBBB With a Difference
Report:Sinus bradycardia Borderline right axis deviation +90o Right bundle branch block V1 â V3 reversed Comment:The RBBB looks strikingly atypical in Lead V1, until one realises that V1 and V3 had been reversed! (Looking at the T wave helps).The tr
Crochetage in ASD
Report:Sinus rhythm Borderline left atrial abnormality Borderline right axis deviation +90o Incomplete right bundle branch block Crochetage in inferior leads suggests ASD Comment:This one did have a fixed split of P2. She was, however, first diagnose
Duchenne Muscular Dystrophy
Report:Sinus tachycardia 135/min Left atrial abnormality Posterolateral infarction pattern c/c muscular dystrophy Comment:The pattern of fully developed Duchenne dystrophy is very characteristic, reflecting the posterolateral scarring of the left ventr
The Critical Rate
Report: Sinus tachycardia VEBs First degree AV block (PR about 0.24â) Right bundle branch block, rate-dependent Critical rate approx. 124/min Comment: The slight deceleration of the sinus rate from top to bottom reveals the critical rate, about 124
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
