Hypercalcæmia
Report: Sinus tachycardia 113/min Borderline left ventricular hypertrophy voltage Short QT interval consistent with hypercalcæmia QT = 0.28â QTc = 0.34â Comment: The ECG is not a very good guide to the degree of hypercalcæmia; this is hardly sur
Romano-Ward Syndrome
Report: Sinus tachycardia 112/min Prolonged QT interval Measured QT = 0.40â Normal QTc for 122/min = 0.335â Actual QTc = = 0.40/0.748 = 0.53" Comment: This is a classical presentation of this uncommon syndrome. The patient was sent to Sydney for
Short QTc in Diltiezam Overdose
Report:Junctional rhythm 56/min Short QT interval 0.36â QTc 0.35â Lead V2 missing Possible old inferior infarction. Comment:The cause of QT interval shortening is iatrogenic32 hypercalcæmia induced by calcium infusion for diltiezam overdose hypo
Hypocalcæmia in Painless Pancreatitis
Report:Sinus rhythm. LVH voltage. Non-specific T wave changes 1 & aVL. Prolonged QT interval 0.53". Q3 and borderline ST segment elevation 2, 3, aVF. Comment:This was an unusual presentation of acute pancreatitis (proven by means of a CAT scan) prese
Prolonged QT Interval
Report: Sinus rhythm 54/min Prolonged QT interval 0.56â QTc 0.53â Comment: This trace suggests anteroseptal infarction, with QS complexes in V1-2 and anteroseptal T wave inversion. However, the âseptalâ q wave in V6 is preserved, which is unusu
Calcium in Electromechanical Dissociation
Report: Supraventricular tachycardia, probably sinus, 180/min Third degree AV block Junctional escape rhythm 26/min Short QT interval consistent with hypercalcæmia Comment: Electromechanical dissociation (EMD) is not an ECG diagnosis. Sometimes the c
Peaked Waves After Head Injury
Report:Sinus rhythm 80/min Borderline right axis deviation +90o Right atrial abnormality Tall peaked T waves ?cause Prolonged QT interval QTc 0.50â Comment:The T waves are, of course, typical of hyperkalæmia: narrow-based, tall and peaked. There
Cerebral Mimicry of MI
Report: Sinus tachycardia 127/min Right atrial abnormality VEB Acute inferolateral (or, better, inferior + anterior) myocardial infarction Prolonged QT interval Comment: The last item, QT prolongation, is the only clue that this is not an ordinary my
Hypothermia: Brain Death
Report: Sinus rhythm 57/min Early transition J waves consistent with hypothermia Prolonged QT interval 0.55â QTc 0.54â Borderline ST segment elevation Comment: The rate is relatively fast and there is no evidence of tremor: the patient was brain
Hyperthyroid Hypercalcæmia on Lithium Therapy
Report:Sinus tachycardia 163/min Borderline right atrial abnormality Borderline short QT interval 0.22â Nonspecific T wave changes Comment:Marked tachycardia with short QT interval gives an illusion of atrial flutter. Indeed, the patient was treated
