Background. Current temporary transvenous pacemaker catheters lack sequential atrioventricular (AV) pacing in synchrony. Therefore, a catheter that could provide sequential AV pacing and maintain synchrony may be useful for patients in sinus rhythm who need temporary pacing.  Objective. The purpose of this study was to describe the first in human experience with a novel temporary AV sequential pacing catheter (TAVSP). Methods. We prospectively identified eligible patients undergoing elective cardiac catheterization in whom the TAVSP catheter was delivered and used for temporary AV sequential pacing. Safety endpoints and device performance data were obtained. Results. Ten subjects were screened and enrolled in the study. TAVSP was delivered in all ten subjects, and AV sequential synchronous pacing was successfully obtained. The pacing catheter achieved an excellent pacing threshold and impedance in all ten patients except for one. There were no adverse events during the pacing procedure. Conclusion. Temporary AV sequential pacing using TAVSP catheter is safe and feasible and may be an alternative to conventional temporary pacing catheters to maintain AV synchrony during temporary pacing.
