Establishing Pacemaker Dependence the Hard Way
Report: Sinus rhythm 1 Third degree AV block 3 Idioventricular rhythm 2 QT interval 0.86” 1 Sinus arrest 2 Pacemaker rhythm 1 Comment: The surgeon, who got rather flustered when told the heart had stopped, certainly established the diagnosis of thi
Giant T Wave Inversion
Report:Sinus rhythm 74/min Advanced second degree AV block Idioventricular rhythm 38/min Giant T wave inversion Prolonged QT interval QTc 0.60â Comment:The tracing is virtually pathognomonic of a preceding Stokes-Adams attack. The T waves are larg
Ischæmic Giant T Wave Inversion
Report:Sinus rhythm Borderline first degree AV block PR 0.22â Incomplete left bundle branch block QRS 0.12â Deep T wave inversion consistent with infarction/ischæmia Prolonged QTc 0.52â Comment:The patient had severe multivessel disease, wit
Hypocalcæmia
Report: Sinus rhythm 70/min Nonspecific lateral T wave changes Prolonged QT interval QTc 0.50â Comment: Although the QT interval is prolonged, the T wave is usually fairly normal in hypocalcæmia. This may explain the rarity of torsades de pointes:
Cerebral T Waves
Report: Sinus tachycardia 120/min Vertical heart position Left ventricular hypertrophy with atypical ST/T changes Prolonged QT interval Comment: It is not possible to determine with certainty whether the QT interval is prolonged or U waves are present
Hypocalcæmia
Report: Sinus rhythm Borderline first degree AV block PR 0.22â Prolonged QT interval QT 0.44â, QTc 0.50â Comment: The long QT is easy to spot because the T waves are relatively prominent from hyperkalæmia. The trace is fairly typical of ren
Romano-Ward Syndrome
Report: Sinus rhythm 54 - 64/min Prolonged QT interval 0.56â Upper limit of normal for rate 57/min 0.41â Comment: The only abnormality is the long QT interval. The Romano121-Ward122 syndrome is similar to Jervell and Lange-Nielsen syndrome123, but
Unread Pre-Discharge ECG
Report: Sinus rhythm 58/min Left axis deviation - 50o Intraventricular conduction defect (IVCD) Probably LAHB + non-specific conduction delay Possible LVH Giant anteroseptal T wave inversion Prolonged QT interval 0.660â (QTc for 58/min 0.45â)
Long PR & Short QT on Digoxin Therapy
Report:Sinus rhythm 75/min Second degree AV block, Möbitz 1 (Wenckebach) Short QT interval 0.29â QTc 0.32â Diffuse nonspecific ST/T changes Consistent with digoxin effect and toxicity Comment:Hospital may be a dangerous place but I would not se
Quinidine: Long QT Interval
Report: Sinus rhythm 82/min Widespread T wave inversion Prolonged QT interval 0.62â QTc for 82/min = 0.37â Comment: This degree of QT prolongation is unusual. The prolongation is idiosyncratic in susceptible individuals and bears little relation t
