Correlations between acute atrial fibrillation and local earth magnetic field strength

Abstract

Objectives: Atrial fibrillation is the most frequent cardiac arrhythmia affecting over 3 percent and appears to be increasing in general population. In addition to widely discussed such risk factor as obesity, arterial hypertension, electrolytes disbalances and dysfunction of thyroid, there is more and more evidence of human heath interactions with environment parameters such as humidity, temperature, the lunar and the solar activity. Atrial fibrillation, a disorder of heart conductive system, in several studies have been indicated as affected by local Earth magnetic field changes. The study was aimed to analyse possible correlations between the power in the local Earth time-varying magnetic field and admission due to atrial fibrillation. Methods: Two-hundred-fifty-one patients diagnosed with acute atrial fibrillation and treated in

Cardiovascular System Interactions With The Local Earth Magnetic Field Fluctuations: A Cohort Study

“…This is the rst study we are aware of that focused on the correlations between cardiovascular function and changes in LMF strength in different frequency ranges and at different fractal levels. Moreover, there are only a few publications on changes in the local MF impact on human health [25,[23][24][25][26][27][28][29], while many publications analyse the impact of the disturbances in the Global MF on living organisms.…”

“…It is known that not only enhancement but also weakening of the resonant frequencies in the magnetic eld can adversely affect the body and that the direction of the LMF intensity change has an impact [21]. Clearly, increased LMF activity in low frequency ranges has a positive effect on the course of ischemic heart disease (IHD) [21,[23][24][25][26][27][28][29] but may increase risk of acute arrhythmias [25]. This study has con rmed that higher LMF intensity in the high frequency ranges is associated with higher number of admissions due to ACS.…”

“…This tendency is most evident in hypertensive patients' group [27]. It was recently found that increased LMF activity in low frequency ranges is associated with increased number of acute atrial brillation and atrial utter [21].…”

“…If we assume that increased GMF intensity, increases vascular tone, and most possible, that the stronger the GMF, the greater vascular tone, which may progress to even life-threatening conditions. Interestingly, a stronger negative effect of the local Earth magnetic eld (LMF) on onsets of acute atrial brillation (AAF) has been observed in hypertensive patients [25][26][27]. LMF strength uctuations resulting in HRV reduction and heart rate (HR) increase may provoke heart arrhythmias [28].…”

Correlation between ST-elevation myocardial infarction, non-ST-elevation myocardial infarction and the local Earth’s magnetic field changes

“…The effects are much more pronounced in patients with CVD and other risk factors [7,9]. A stronger association between arrhythmias, such as acute atrial fibrillation, and fluctuations in local magnetic field activity has been found in groups of individuals with arterial hypertension [4]. Studies show that the intensity of the magnetic field at different frequencies affects the body differently: in the low frequency range it has a positive effect on human health, while in the higher frequency range it is associated with increases in health disorders [2][3][4].…”
