This brief review discusses the potential and prospects of using electrocardiogram (ECG) signal directly for frequency analysis to study processes cardiac regulation. The advantage ECG over generally accepted RR series is its higher sampling rate: 1000 samples per second (sps) vs. 4 sps series. may be important, first all, when analyzing interaction regulation with other periodic in body, such as activity neural circuits brain.

Circadian rhythms are governed by a biological clock, and known to occur in variety of physiological processes. We report results on the circadian rhythm heart rate observed using wrist-worn wearable device (Fitbit), consisting over 17,000 individuals course 30 days. obtain an underlying from time series modeling as sum first two Fourier harmonics. The harmonic accounts for approximate 24-hour rhythmicity body while second non-sinusoidal perturbations. From diurnal modulation rate, we following parameters: (i) amplitude modulation, (ii) bathyphase, (iii) acrophase. also consider activity show that most individuals, lags activity. widespread availability smartwatches trackers may enable who interested observing their numerous parameters, measure longitudinal changes parameters response various health-related variables such diet, sleep, exercise, or illness.

The activities of living beings fluctuate according to seasonal changes and circadian rhythms. interaction organisms with their environment, notably weather conditions night–day cycles, modulate homeostatic mechanisms influence physiological responses in stressful situations. In humans, it is well established that cardiovascular events such as myocardial infarction, stroke acute heart failure more frequently occur winter than summer season (non-tropical regions) the morning evening. While effects medications vary during day, rhythms on outcomes invasive interventions subject conflicting debates. This paper analyzes impact variability occurrence complications cardiac surgery interventional cardiology.

Defects in Aryl hydrocarbon receptor nuclear translocator-like 1 (ARNTL), a central component of the circadian clock mechanism, may promote or inhibit induction inflammation by monocytes/macrophages, with varying effects on different diseases. However, ARNTL's role monocytes/macrophages under chronic kidney disease (CKD), which presents systemic inflammation, is unclear. Here, we report that expression
