| Abstract | *We developed a noninvasive method to provide beat-to-beat changes in the PR interval that accompany normal fluctuations in the heart rate. A well reproducible PR interval signal that fluctuated in a way similar to the heart rate exhibited spectral frequency distribution similar to the heart rate. The PR interval and the heart rate signals were analyzed in the PR interval-heart rate (PR-HR) diagram using our model of AV conduction. The observed PR-HR patterns could be explained by the model only when we assumed different neural inputs to the SA node and the AV node. This suggests that noninvasive measurements of the PR interval signal could be used in the study of autonomic neural influences to the heart connected with the left and right distribution of the cardiac nerves. | |
