Hypomagnesæmia Torsades
Report:Sinus rhythm 51/min Prolonged QT interval 0.56â QTc 0.52â Comment:The patient had several admissions with alcohol-related illnesses, all of which featured hypokalæmia, hypomagnesæmia or both, with corresponding repolarisation abnormalities
Long QT Interval Post-VF
Report:Sinus rhythm 65/min Right axis deviation +100o Late transition Long QT interval 0.54â QTc 0.56â Nonspecific ST/T changes Comment:She died from cerebral sequelae of her VF arrest; it is reasonable to ascribe the QT prolongation to cerebral
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
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
Snow-Boarderâs Snow Hypothermia
Report:Sinus bradycardia 37/min Intraventricular conduction defect c/c hypothermia QRS 0.20â Prolonged QT interval 0.73â QTc 0.58â Comment:The unfortunate youth was stripped in the snow fields to cool him, but his skull and brain were smashed b
Long QT after Cerebral Trauma
Report:Sinus tachycardia 103/min Small frontal plane voltage Diffuse T wave inversion Prolonged QT interval Comment:Some of the repolarisation changes can be due to U waves merged with T waves; while it cannot be excluded, it does not matter. The pota
Idioventricular Rhythm Mime of RVH
Report:Idioventricular (?fascicular) rhythm 57/min Giant T wave inversion Prolonged QT interval Comment:The QRS morphology suggests, superficially, RVH. In V1, however, it is not a true qR complex â there is a small primary R wave as well: itâs an
Hypokalæmia - Giant U Waves
Report:Sinus rhythm 52/min Borderline right axis deviation +91o Right atrial abnormality Late transition Prolonged QT (QU) interval 0.72â Comment:It would not be possible to tell whether the apparent QT prolongation is due to a large U wave that ha
Hypercalcæmia
Report:Sinus rhythm 89/min Short QT interval c/c hypercalcæmia Comment:The actual QT measurement, just over 0.30â, yields a QTc of 0.38â â not a useful tool in a patient with calcium 4.64 mmol/L. Marriott suggest measuring the interval to the ape
Sotalol Overdose
Report:Sinus rhythm 62/min 2:1 AV block Ventriculophasic sinus arrhythmia Prolonged QT interval 0.58â QTc 0.58â Comment:The blocked alternate P waves are not very obvious, superimposed on prolonged, themselves rather wavy, T waves. Also, alternat
