The aim of this study is to analyse and identify the factors responsible for the heart rate variability component that is synchronised with the locomotor rhythm, which has so far been regarded as noise, in patients with cardiovascular disease. Heart rate fluctuates under the influence of various factors and is also affected by the rhythm of exercise. We have studied the variability of heart rate rhythm during exercise and have reported that heart rate rhythm is influenced and drawn in by the rhythm of gait and that the strength of the influence from the exercise rhythm is related to exercise tolerance and age. In this study, data will be collected in patients with impaired circulatory function with the aim of identifying factors contributing to heart rate rhythm fluctuations synchronised with exercise rhythms for use in the assessment of exercise and cardiovascular function.

(1) Study design.
Collaborative, cross-sectional and observational study of International University of Health and Welfare and International University of Health and Welfare Narita Hospital
(2) Evaluation items and methods
(1) Primary endpoints
Left ventricular ejection fraction, heart failure stage, heart rate variability component during exercise
(2) Secondary endpoints
Skeletal muscle pump function, autonomic nerve activity, maximal oxygen uptake, anaerobic metabolic threshold
(3) Statistical analysis methods
Subjects were divided into two groups according to heart failure type, and the exercise heart rate variability component, skeletal muscle pump function and autonomic function were compared using an unpaired t-test. The significance level is set at a risk rate of less than 5%.
(4) Observation and examination items (samples and information to be used) and methods
The following items will be observed and examined
1) Basic subject information (age, sex, height, weight, diagnosis, medical history, treatment history and medication status): obtained from medical records.
2) Echocardiography results (left ventricular ejection fraction): obtained from medical records.
3) Cardiopulmonary exercise stress test (heart rate variability component during exercise, anaerobic metabolic threshold, maximum oxygen uptake): analysed by 12-lead ECG and expiratory gas analyser. ECG data are converted to R-R intervals and analysed for heart rate variability using the maximum entropy method with analysis software (MEMCALC). Components that match the exercise frequency are extracted as heart rate variability components during exercise.
4) Skeletal muscle pump function (single leg venous output is extracted using air plethysmography).
