Design outcomes
Primary
| Measure | Time frame |
|---|---|
| After anesthetic induction and catheter insertion, CSACT (calculated sinoatrial conduction time) is measured during first EPS (electrophysiological study). And then, remifentanil is administered at a rate of 0.2 or 0.4 microg/kg/min. Almost 10 minutes after remifentanil administration, second EPS and CSACT measurement is performed. | — |
Secondary
| Measure | Time frame |
|---|---|
| As with mentioned above, CSNRT (corrected sinus node recovery time), RR interval, and AH interval are measured before and during remifentanil administration. | — |
