Wenckebach AV Block in Acute Inferior Infarction
Report:Sinus rhythm 90/min Möbitz 1 (Wenckebach) second degree AV block Intraventricular conduction defect (IVCD) QRS 0.12â Acute inferior infarction Comment:The most striking feature are the marked precordial reciprocal changes, indicating extens
LBBB: Primary T Wave Changes
Report:Sinus rhythm 65/min First degree AV block PR 0.28â Left bundle branch block Primary T wave changes 2, 3 and aVF Comment:LBBB always causes repolarisation changes directed opposite the main QRS deflection, especially its terminal half. They a
Wrong Reason for the Right Report
Report:Sinus tachycardia 128/min Third degree AV block Junctional escape rhythm 38/min Acute inferior and right ventricular infarction (Right-sided V leads as labelled) Atrial infarction Comment:The report followed a previous one, on a preceding ECG
Inferior Infarction: Blocks and Arrhythmias
Report:Sinus tachycardia 122/min Second degree AV block, unspecified Junctional escape beats and rhythm 46/min Non-phasic aberrant conduction Acute inferior infarction Comment:It is said that the presence of 2o AV block in inferior infarction denotes
Inferior MI, VEBs & Persistent Wenckebach
Report:Sinus tachycardia 104/min VEBs, frequent, multiform Second degree AV block, Möbitz 1 (Wenckebach) Late transition Nonspecific intraventricular conduction delay (IVCD) Acute inferior infarction Anterolateral ST/T changes c/w MI/ischæmia Co
Giant T Wave Inversion
Report:Sinus rhythm 74/min Advanced second degree AV block Idioventricular rhythm 38/min Giant T wave inversion Prolonged QT interval QTc 0.60â Comment:The tracing is virtually pathognomonic of a preceding Stokes-Adams attack. The T waves are larg
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
Long PR & Short QT on Digoxin Therapy
Report:Sinus rhythm 75/min Second degree AV block, Möbitz 1 (Wenckebach) Short QT interval 0.29â QTc 0.32â Diffuse nonspecific ST/T changes Consistent with digoxin effect and toxicity Comment:Hospital may be a dangerous place but I would not se
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
P Wave or T Wave?
Report:Sinus bradycardia 37/min. Left atrial abnormality . First degree AV block. Left bundle branch block Comment:The T wave is peaked and sharply demarcated from the preceding ST segment, mimicking a P' wave. Sequential strips (Fig 224a below) gradu
