Erythromycin Torsade de Pointes
Report:Sinus tachycardia 122/min Nonspecific T wave changes Prolonged QT interval Comment:This is one of those tracing where inspection is better than attempts at precise measurement and QTc calculation: there is a clear-cut long ST segment and the T w
AV Block: Nodal or Ventricular?
Report:Sinus rhythm Second degree AV block Intermittent right bundle branch block & left posterior hemiblock Prolonged QT interval Comment:The PR interval lengthens between the first and the second beat, but fails to grow observably longer between the
Congenital Heart Block with Long QT Interval
Report: Sinus rhythm 100 - 110/min Third degree AV block Junctional escape rhythm 48/min VEB SVEB Prolonged QT interval 0.60â QTc 0.53â Comment: This case has been reported73. While it is not possible to exclude post-syncopal QT prolongation i
Sino-Atrial Wenckebach
Report:Sinus rhythm Sino-atrial exit block, Möbitz 1 Left atrial abnormality (LAA) AV block, Möbitz 1, incomplete sequences Prolonged QT interval Comment:This is an example of one form of block preventing the full expression of another: the AV nod
Sinus Bradycardia
Report:Sinus bradycardia 32/min Short QT interval QTc 0.31â Comment:Marked sinus bradycardia almost always signifies some form of sinoatrial block, often in the setting of sick sinus syndrome. The short QT interval is more interesting. The most like

Thioridazine Overdose
Report:Junctional/sinus rhythm VEB, dimorphic couplet Non-sustained ventricular tachycardia (torsade de pointes) Comment:The torsades were very frequent, but the 12-lead ECG did not catch the best of them. Nevertheless, the one shown here is reasonably
Sotalol Sensitivity
Report:Atrial ?junctional bradycardia 42/min VEB Long QTc 0.54â Comment:The first beat is distorted by movement artefact: its repolarisation in L1 and L3 and preserved QRS shape in simultaneous L2 distinguish it from a VEB. The striking abnormality
