[Characteristics of the heart rate during mental tracing of heartbeats in healthy subjects].
Mental counting of self heartbeats results in changes of parameters of heart rhythm--domain and other frequencies of the RR-intervals, especially, high frequencies (0.15-0.4 Hz), which are relevant to respiration. The accuracy of mental counting of the heartbeats (the ratio of traced beats to the number of registered ones) corresponds to individual relations between the frequencies, regularity, and total number of the heartbeats. A possibility of the voluntary regulation of respiration as the cause of changes in the heartbeat frequency is discussed in terms of the center-periphery integration (system approach) for optimal perception of self heartbeats.
