Prolonged QT Interval
Report: Sinus rhythm 51/min VEB Left anterior hemiblock (QRS axis -45o) Old anteroseptal infarct Diffuse ST/T changes [!xe "T wave:inversion:post-LBBB-like VT" \b!] Markedly prolonged QT interval[!xe "QT interval:sotalol" \b!] QT 0.68" (QTc 0.62")
Agonal Rhythm & Paper-End Mark
Report:Junctional or accelerated idioventricular rhythm (AIVR) 52/min. 1:1 retrograde conduction. Comment:The sinus rhythm is completely regular in brain death and usually faster than while vagal tone was still extant, except in profound hypothermia. Th
Hypokalæmia
Report:Sinus rhythm. Borderline left axis deviation -30o. Prominent repolarisation changes suggestive of hypokalæmia. Comment:The patient had severe metabolic acidosis and marked, paralysing hypokalæmia (K 1.7 mEq/L) No cause was found during her 4-d
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
Swinging T Waves
Report:Sinus rhythm. Incomplete RBBB. Respiratory phasic reversal of T wave polarity. Comment:In the right precordial leads, respiratory movement has at times striking effect on the T wave and, less often, the QRS complex itself. This may of clinical i
Electromechanical Association: Spurious VT
Report:Sinus tachycardia. Incomplete RBBB. Movement artefact. Comment:The movement artefact occurs at the same rate as the pulse. The patient had a forceful precordial impulse, which visibly moved the lead attachment. I could not reproduce the original
Pseudoalternans
Report:Sinus tachycardia 111/min VEBs in bigeminy Fusion beats Comment:The first fusion beat appears at the end of the top strip. The middle strips show VEBs in bigeminy, without fusion; the bottom strip shows later-coupled VEBs in fusion, mimicking al
True Alternans in Cardiac Tamponade
Report:Sinus tachycardia 126 - 132/min Electrical alternans Comment:By definition, there must be no change in rhythm or conduction for alternans to be diagnosed. In this case, the mechanism is the "swinging" of the heart, pendulum-like, within the peric
LVH: Left Ventricular Volume Overload
Report:Atrial fibrillation with controlled response (56/min) Left anterior hemiblock (frontal plane QRS axis -50o) Poor R wave progression Left ventricular hypertrophy (RV5 > 25 mm) Prominent T waves consistent with LV volume overload Comment:The pat
Global T Wave Inversion
Report:Sinus rhythm Normal axis LVH with ST/T changes ± ischæmia Comment: The peculiar thing is that this kind of T wave inversion has a striking preponderance in the elderly woman and is usually not ischæmic, let alone infarctional203. The pattern
