Key result

Cardiorespiratory synchronization was more abundant in heart transplant patients than normal subjects, and synchronization epochs were significantly shorter in surrogate data.

Implication

Supports authenticity of cardiorespiratory synchronization post-transplant; hypothesis-generating and requires prospective validation before clinical consideration.

Key Points

This work aims to determine the authenticity of synchronization between heart rate and respiration rate.
Developed an algorithm for automatic detection of synchronization epochs.
Applied the algorithm to recordings from 13 normal subjects and 13 heart transplant patients.
Compared statistical properties of synchronization in actual and surrogate data sets.
Synchronization was observed in all groups, with lower prevalence in normal subjects compared to heart transplant patients.
The duration of synchronization epochs was significantly shorter in surrogate data for both groups.
Findings suggest that some synchronization epochs are real rather than artifacts.

Toledo et al. (2002) conducted an observational in Heart transplant (n=26). Heart transplant vs. Normal subjects was evaluated on Duration and abundance of synchronization epochs. Cardiorespiratory synchronization was more abundant in heart transplant patients than normal subjects, and synchronization epochs were significantly shorter in surrogate data.
