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
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
âTrifascicularâ Block
Report: Sinus rhythm Left atrial abnormality (LAA) First degree AV block PR 0.28â Left posterior hemiblock Right bundle branch block Old anterior infarction Comment: The term âtrifascicularâ is sufficiently polysyllabic and scientific-soundin
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
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
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
LBBB with RAD: Acute Inferior Infarction
Report:Sinus rhythm 96-100/min Third degree AV block Junctional escape rhythm 45/min Left bundle branch block Right axis deviation +95o Acute inferior infarction Comment:Three contributors to heart failure are present in this trace: Acute infarction
Left Axis Deviation: Inferior Infarction
Report:Sinus rhythm 60/min Left axis deviation â60o Inferior and anterior infarction, probably old Comment:Deep Q waves of inferior infarction are a common cause of LAD in cardiac patients. They distinguish infarction from LAHB, which requires rS mor
Right Axis Deviation: Lateral Infarction
Report:Sinus tachycardia 110/min Right axis deviation +150o Postero-antero-lateral infarction, probably recent Comment:The Q waves in the (high) lateral leads 1 and aVL are responsible for the RAD. They are called âlateralâ by convention and do not
RBBB with Amputated Primary R Wave
Report:Sinus rhythm 95/min Right axis deviation Right bundle branch block Recent anterior infarct Comment:The QR complex in V1 is still RBBB since the delay is all in the RV territory. Before the infarction it was an rSrâ of normal duration (not sho
