(a) Ventricular tachycardia shortly after arrival of the patient to the emergency department. (b) Restoration of sinus rhythm, with atrial-tracking ventricular pacing following intubation and amiodarone treatment.

Shortly after arrival, she developed a brief episode of pulseless electrical activity followed by sustained ventricular tachycardia (Figure 1(a)), which gradually accelerated, causing repetitive unsuccessful ICD shocks. She was intubated and IV amiodarone was administered, resulting in resolution of the ventricular tachycardia (Figure 1(b)).
(a) Initial chest radiograph immediately following intubation revealing a large left-sided pneumothorax. Small arrows show the outline of the pneumothorax, partially obscured by the ICD. The large arrow shows depression of the left hemidiaphragm, which is a sign of tension pneumothorax. (b) Resolution of the pneumothorax after prompt chest tube placement.

Chest radiograph revealed large left-sided tension pneumothorax, with depression of the left hemidiaphragm (Figure 2(a)) which was promptly drained, causing positive gush of air after chest tube placement, suggestive of tension pneumothorax (Figure 2(b)).
