Systemic sclerosis is an immunological disorder characterized by tissue fibrosis and multi-organ dysfunction.1 The accompanying images exhibit electrocardiographic changes in severe systemic sclerosis.
Advanced 3:
1 atrioventricular block, best observed in Lead Vi, suggests extensive fibrosis of the conduction system (Image A). While one P wave is buried in the T wave (black arrows), two are evident (red arrows) along the isoelectric line. Bradyarrhythmia related prolonged QT interval, best measured in Lead II represents increased risk for torsades-de-pointes, a polymorphic ventricular tachyarrhythmia. Additionally, right bundle branch block with giant T wave inversions (T wave depth > 10 mm) in precordial leads V2- 4 suggests pulmonary hypertension. Post-induction the rhythm abruptly changes to torsades-de-pointes (Image B) necessitating defibrillation.
