2. Ventricular programmed stimulation inducing typical AVNRT that degenerates to AF. A, Typical AVNRT (cycle length 280 ms) is induced with ventricular programmed stimulation.
Ventricular programmed stimulation inducing typical AVNRT that degenerates to AF. A, Typical AVNRT (cycle length 280 ms) is induced with ventricular programmed stimulation. The dashed arrow shows slow-pathway activation with retrograde fast-pathway activation occurring simultaneously with ventricular depolarization. B, Degeneration from AVNRT to AF 6 seconds after tachycardia initiation without a prior increase in heart rate during AVNRT. CS indicates coronary sinus; RV, right ventricle; CT, crista terminalis; d, distal; and p, proximal.
