Figure S1. Response to an early atrial extrastimulus during SVT. Surface leads and intracardiac electrograms are shown, with an early atrial extrastimulus delivered from the proximal coronary sinus with a short coupling interval of about 210 ms. The extrastimulus captures the atrium and advances the next His and ventricular depolarization and resets the tachycardia without termination. H-H intervals are indicated by the calipers.
Figure S2. Response to a second early atrial extrastimulus during SVT. Surface leads and intracardiac electrograms are shown, with an additional early atrial extrastimulus delivered from the proximal coronary sinus with a short coupling interval. The extrastimulus captures the atrium and advances the next His and ventricular depolarization and resets the tachycardia without termination. H-H intervals are indicated by the calipers.
Figure S3. Response to a third early atrial extrastimulus during SVT. Surface leads and intracardiac electrograms are shown, with an additional early atrial extrastimulus delivered from the proximal coronary sinus with a short coupling interval. The extrastimulus captures the atrium and advances the next His and ventricular depolarization and resets the tachycardia without termination. H-H intervals are indicated by the calipers.
Figure S4. Response to a fourth early atrial extrastimulus during SVT. Surface leads and intracardiac electrograms are shown, with an additional early atrial extrastimulus delivered from the proximal coronary sinus with a short coupling interval. The extrastimulus captures the atrium and advances the next His and ventricular depolarization and resets the tachycardia without termination. H-H intervals are indicated by the calipers.
Figure S5. Response to a fifth early atrial extrastimulus during SVT. Surface leads and intracardiac electrograms are shown, with an additional early atrial extrastimulus delivered from the proximal coronary sinus with a short coupling interval. The extrastimulus captures the atrium and advances the next His and ventricular depolarization and resets the tachycardia without termination. H-H intervals are indicated by the calipers.
