Abstract

Background - Reappearance of low-frequency (LF) (±0.10 Hz) oscillations in RR interval (RR) after cardiac transplantation is indicative of sympathetic efferent reinnervation. We hypothesized that restored LF oscillations in RR in heart transplant recipients (HTRs) are linked to oscillations in muscle sympathetic nerve traffic (MSNA). Methods and Results - RR, RR variability, and MSNA were recorded 5±2 months (n=7, short-term HTRs) and 138±8 months (n=7, long-term HTRs) after heart transplantation and compared with matched hypertensive patients (n=7). A coherence function determined the coupling between LF oscillations in MSNA and RR. RR variance did not differ between short-term and long-term HTRs. However, LF variability was only 1±0.5 ms² in the short-term HTRs but was 15±8 ms² in the long-term HTRs (P
