“…For example, 6-week exposure of albino Wistar rat males to electromagnetic field radiation from a dual transceiver mobile phone led to a decrease in maximal to minimal heartbeat intervals ratio (Usman et al, 2020). It has also been reported that geomagnetic storms can cause changes in human heart rate variability (Chernouss et al, 2001;Janashia et al, 2022). Slow changes in the vertical component of GMF in the millihertz range led to an increase in heart rate variability in male volunteers (Vasin et al, 2019).…”

“…A few studies have indicated that the exposure of adult humans to HMF leads to decreased heart rate and increased heart rate variability (Gurfinkel et al, 2016;Demin et al, 2021). Long-term monitoring of cardiac activity indicated a relationship between heart rate variability and weak natural geomagnetic variations in rabbits (Chibisov et al, 2004;Gmitrov and Gmitrova, 2004), rats (Kuzmenko et al, 2019), and humans (Chernouss et al, 2001;Janashia et al, 2022).…”

The magnetic environment may influence the functioning of the cardiovascular system. It was reported that low-frequency and static magnetic fields affect hemodynamics, heart rate, and heart rate variability in animals and humans. Moreover, recent data suggest that magnetic fields affect the circadian rhythms of physiological processes. The influence of the magnetic environment on heart functionating during early development has been studied insufficiently. We utilized transparent zebrafish embryos to evaluate the effect of the hypomagnetic field on the characteristics of cardiac function using a noninvasive optical approach based on photoplethysmographic microscopic imaging. The embryos were exposed to the geomagnetic and hypomagnetic fields from the second to the 116th hour post fertilization under a 16 h light/8 h dark cycle or constant illumination. The exposure of embryos to the hypomagnetic field in both lighting modes led to increased embryo mortality, the appearance of abnormal phenotypes, and a significant increase in the embryo’s heartbeat rate. The difference between maximal and minimal heartbeat intervals, maximal to minimal heartbeat intervals ratio, and the coefficient of variation of heartbeat rate were increased in the embryos exposed to the hypomagnetic field under constant illumination from 96 to 116 h post fertilization. The dynamics of heartbeat rate changes followed a circadian pattern in all studied groups except zebrafish exposed to the hypomagnetic field under constant illumination. The results demonstrate the importance of natural magnetic background for the early development of zebrafish. The possible mechanisms of observed effects are discussed.

“…This supports the previous study of [72] . This latitude-dependent behavior can be attributed to the Earth's varying magnetic field strength, which is strongest near the poles and weakest near the equator [73] . PPEFs are driven by the leakage of high-latitude convection electric fields to low latitudes.…”

The aim of this study was to identify associations of the parameters of heart rate variability (HRV) with the variations in geomagnetic activity (GMA), solar wind, and cosmic ray intensity (CRI) in patients after coronary artery bypass grafting or valve surgery in Kaunas, Lithuania, during 2008–2012. The data from 5-minute electrocardiograms (ECGs) in 220 patients were used. ECGs were carried out at 1.5 months, 1 year, and 2 years after the surgery (N = 495). A lower (higher) very-low-frequency-band (VLF) and a higher (lower) high-frequency band (HF) in normalised units (n.u.) were associated with a low maximal daily 3-hourly ap (the DST index > 1). A lower mean standard deviation of beat-to-beat intervals (SDNN) and VLF, LF, and HF powers were lower in patients when Ap < 8 occurred two days after the surgery, and a low solar wind speed (SWS) occurred two days before the ECG. The effect of CRI was non-significant if the linear trend was included in the model. Low GMA and a low SWS may effect some HRV variables in patients after open-heart surgery. The GMA during the surgery may affect the SDNN in short-term ECG during the longer period.
