ECG 1. There is atrial fibrillation. Three QRS-T complexes are seen, with the latter two having similar QRS morphology. These beats may originate from the ventricles or atria.

ECG 2. The initial part shows QRS complexes with similar morphology as ECG 1, likely presenting a supraventricular rhythm. Three short bursts of ventricular tachycardia occur.

ECG 3. Repeated bursts of VT.

ECG 4. There are now visible ST segment elevations and Q waves not seen on the initial recording (ECG 1).
