Propoxyphene Toxicity
Report:Supraventricular tachycardia, possibly sinus, 118/min First degree AV block PR 0.24â Intraventricular conduction defect QRS 0.15â Comment:This probably is a sinus tachycardia with P waves masked in many leads through prolonged QT interval;
Histiocytosis X Cor Pulmonale
Report:Sinus tachycardia 102/min Right atrial abnormality Left atrial abnormality Right axis deviation +110o RSRâSâ in V1 Poor R wave progression Right ventricular hypertrophy Comment:Most patients with a trace like this would have emphysema, b
Hypothermia: Atrial Fibrillation
Report:Atrial fibrillation with ventricular response 70 â 96/min Hypothermic humps (J waves, Osborn waves) and prolonged QTc suggestive of hypothermia[! XE "J wave" \t "See Hypothermia" !][! XE "Osborn wave" \t "See Hypothermia" !] Nonspecific T wave
Myopericarditis
Report:Sinus rhythm 72/min ST segment elevation c/c pericarditis Comment:The ST elevation involves both sets of leads â frontal and chest leads â and V6 is involved; electrocardiographic acute pericarditis. No other diagnosis is suggested. The next
Sinus Tachycardia in Mitral Stenosis
Report:Sinus tachycardia 114/min Left atrial abnormality Comment:The trace is not really suggestive of mitral stenosis. Apart from the obviously increased PTF in V1, the only clue â a weak one - is small R wave in L1. Yet he was one of the most inter
RVH in Single Ventricle Transposition with Pulmonary Stenosis
Report:Sinus rhythm approx 125/min (less than 132/min normal for 3 years) Third degree AV block Junctional rhythm 66/min Right atrial abnormality (P congenitale pattern) Right ventricular hypertrophy Comment:The congenital defects in the title above
Mime of Cerebral Injury
Report:Sinus rhythm 75/min Borderline low voltage Poor R wave progression Diffuse T wave inversion Prolonged QT interval Comment:The tracing is quite suggestive of a cerebral event, but there was none. Cardiac catheter showed segmental akinesia and h
Complete Chest Lead Reversal
Report:Atrial pacemaker rhythm 78/min Complete chest lead reversal Possible left ventricular hypertrophy Comment:This is a rare variant of lead reversal. It happens when the entire block of V-lead terminals is rotated 180o and inserted into the machine
Early Repolarisation in Inferior Leads
Report:Sinus rhythm 66/min Inferior ST segment elevation LVH voltage Comment:The unusual elevation is confined to the inferior leads. The slight one in V1-2 is normal. There is also some 0.5 mm depression in aVL, but true reciprocal changes are usually
Cooling Cardiac Arrest
Report:Sinus rhythm 99/min Intraventricular conduction defect c/c hypothermia Nonspecific ST/T changes Prolonged QT interval 0.40â QTc 0.84â Movement artefact V3 Comment:The hypothermic humps are rather inconspicuous, but there once one looks fo
