ECG 1. The initial rhythm is atrial fibrillation. The fifth beat is a ventricular premature beat. A ventricular tachycardia (VT) emerges. As evident, ventricular tachycardia may appear more polymorphic in one lead (the upper lead).
ECG 2. Although the signal in the upper lead appears very disorganized, there are visible QRS complexes. The signal in the lower lead shows that the rhythm is a polymorphic ventricular tachycardia (or even flutter).
ECG 3. Continued polymorphic ventricular tachycardia / flutter.
ECG 4. Continued polymorphic ventricular tachycardia / flutter.
Sudden cardiac arrest: Case 5
ECG 1 . Sinus rhythm interrupted by polymorphic VT. ECG 2 . Polymorphic VT. ECG 3 . Polymorphic VT progresses to ventricular fibrillation (VF). ECG 4 . Polymorphic VT progresses…
Sudden cardiac arrest: Case 7
ECG 1 . The underlying rhythm is atrial fibrillation, which is interrupted by polymorphic ventricular tachycardia (VT). ECG 2 . Polymorphic ventricular tachycardia. ECG 3 .…
