2. FIGURE 1
Electrocardiographic rhythm strips (lead 2) of nonsustained wide QRS tachycardia (rate 115 bpm) prior to flecainide administration (A, upper) and a new sustained wide QRS tachycardia (rate 214 bpm) after three doses of oral flecainide (B, lower).

3. FIGURE 2
Spontaneous nonsustained ventricular tachycardia before (A, upper) and spontaneous sustained ventricular tachycardia after flecainide (B, lower). Shown from top to bottom in each panel are leads (L) 1, 2 and 3 and lead V1 (V1) of the electrocardiogram recorded simultaneously with the right atrial (RA) and His bundle (HB) electrograms. In panel A, the first sinus beat is followed by four ventricular (V) beats dissociated from the atrial (A) activity, then another sinus beat. In panel B, sustained ventricular tachycardia (VT) at a cycle length (CL) of 300 ms is shown. There was also atrioventricular dissociation at the time of flecainide induced sustained VT. The numbers in both panels indicate the cycle lengths in milliseconds.
