Figure 3. Adenosine increases the corrected indirect SAN recovery time (cSNRTi).

Figure 3

Optical action potential (OAP) and atrial ECG during and after termination of pacing at 3.3Hz (A) and 7Hz (B) are shown. The blue OAPs are from the low center part of the SAN; the green atrial OAPs are from the CT. The extracted SAN signals (dark blue) are indicated as “extracted SAN”. Corrected indirect SAN recovery time (cSNRTi) and sinus cycle length (SCL) are shown for each recording. Real SNRT (cSNRTr) is shown for the last recording where SAN exit block was present. “Paced SAN” means that SAN was paced by atria.
