CVA Simulating Infarction
Report: Sinus rhythm 92/min Probable acute anterior infarction Borderline ST segment elevation in the inferior leads Comment: There are no reciprocal changes and the QT is prolonged, but it could still be an infarct. In the context of proven cerebral h
LVH with ST/T Changes and Streptokinase
Report: Sinus rhythm 72/min Borderline left atrial abnormality Borderline left axis deviation â30o Left ventricular hypertrophy with ST/T changes ST/T changes also consistent with ischæmia Intraventricular conduction delay (IVCD) QRS 0.12â Com
Idiopathic Hypothermia
Report: Sinus bradycardia 46/min Osborn waves (J waves, hypothermic humps) Prolonged QT interval 0.65â QTc 0.57â Tracing suggests hypothermia. Comment: The temperature was 29oC. The only thing missing is evidence of shivering, seen in approximate
Traumatic Pericarditis
Report: Sinus tachycardia 100/min Diffuse ST segment elevation suggests pericarditis Comment: The ST segments started to rise within 12 hours of injury and reached maximum at 36 hours, when this tracing was obtained. The admission ECG, taken approximate
Movement Artefact
Report: Sinus rhythm Movement artefact Comment: Once looked for, sinus P waves are easily discerned in front of most beats; the rest cannot, therefore, be genuine atrial activity. The regular normal rate is a clue that the rhythm is not AF, which would
Atrial Fibrillation in Hypothermia
Report: Atrial fibrillation with average ventricular response 97/min J (Osborn) waves suggest hypothermia Prolonged QT interval Comment: The QT interval is only mildly prolonged for 30oC; the prolongation is most obvious in short cycles, where QT shoul
Myocarditis
Report: Sinus rhythm 88/min Prolonged QT interval QTc 0.50â Diffuse T wave inversion Comment: T wave changes, by themselves, are virtually never diagnostic of anything. In this setting, they are consistent with myocarditis or ischæmia. They are dee
Normal Infant ECG
Report: Sinus rhythm 144/min Axis +110o RsV1 Normal trace Comment: The heart rate of a normal infant between one and three months is 120 to 180/min; the normal range widens over the next three months to 106 â 186/min88. The rest of the trace would
Amyloid Pseudoinfarction
Report:Sinus rhythm 85/min VEB Small voltage in frontal leads Old inferior and extensive anterior infarctions Comment:The extensive infarction is, of course, an ECG diagnosis. This case demonstrates the need for differential diagnosis even (or especia
Small Voltage in Anasarca
Report: Sinus rhythm 98/min Absolute small voltage Diffuse nonspecific ST/T changes Prolonged QT interval Comment: The entire QRS complex is less than 5 mm in the frontal leads and less than 8 mm in the precordial leads. The commonest cause is extensi
