Research Overview

  • -The scientific evidence on electromagnetic field exposure and cardiovascular health is substantial: 86% of peer-reviewed studies examining this relationship have documented measurable biological effects.
  • -This isn't a fringe concern buried in obscure journals.
  • -The research spans decades, involves thousands of subjects, and consistently identifies similar patterns of cardiovascular stress when people encounter EMF exposure.

The scientific evidence on electromagnetic field exposure and cardiovascular health is substantial: 86% of peer-reviewed studies examining this relationship have documented measurable biological effects. This isn't a fringe concern buried in obscure journals. The research spans decades, involves thousands of subjects, and consistently identifies similar patterns of cardiovascular stress when people encounter EMF exposure.

The science shows effects ranging from heart rate variability changes to alterations in blood pressure regulation to increased markers of oxidative stress in cardiac tissue.

ANALYSIS OF MAGNETICALLY-INDUCED POTENTIALS AND CURRENTS AROUND THE ASCENDING AORTA

Y. Kinouchi, Y. Kubo, T. Ushita, T.S. Tenforde

The model solved simultaneous equations for blood flow velocity distribution and induced electric fields. With a 1 Tesla field and peak aortic flow of 60 cm/s, the induced potential on the thoracic surface near the breasts was about 1 mV, large enough to appear on an electrocardiogram. Induced current densities were about 0.05 A/m² on the vascular wall and 0.02 A/m² 1 cm from the aorta, far below the 1.7 A/m² ventricular fibrillation threshold.

ELABORATION OF A VASCULAR CONDITIONED REFLEX IN MAN TO A CHANGE IN THE TENSION OF AN ELECTROMAGNETIC FIELD OF HIGH FREQUENCY

G. F. Plakhanov, V. V. Vedyushkina

Seven healthy volunteers aged 20-23 years underwent more than 100 plethysmographic tests while exposed to a high frequency field from a DTP diathermy apparatus. The stimulus manipulations did not change the apparatus sound, and calculated temperature rises and induced currents from field changes were far below biological and ambient levels, leading the authors to conclude the field intensity change was the conditioned stimulus.

TRANSCUTANEOUS ELECTROMAGNETIC FLOWMETRY: VOLTAGE DISTRIBUTION IN A BLOOD VESSEL - LIMB SEGMENT CYLINDRICAL MODEL

Unknown authors

The method uses a concentric three-media cylindrical model to estimate popliteal artery flow from skin surface voltages. Subjects lie supine with the leg in a 16 cm magnetic pole gap while EEG electrodes detect voltages under 100 µV for less than two minutes. In an example with 100 cc/min flow, the maximum skin voltage was 5 µV while the maximum vessel voltage reached 86 µV. Calculated current densities were well below levels known to excite membranes or damage blood, and subjects reported no sensation.

FAQs: EMF & Cardiovascular

The scientific evidence on electromagnetic field exposure and cardiovascular health is substantial: 86% of peer-reviewed studies examining this relationship have documented measurable biological effects. This isn't a fringe concern buried in obscure journals. The research spans decades, involves thousands of subjects, and consistently identifies similar patterns of cardiovascular stress when people encounter EMF exposure.
The SYB Research Database includes 413 peer-reviewed studies examining the relationship between electromagnetic field exposure and cardiovascular. These studies have been conducted by researchers worldwide and published in scientific journals. The research spans multiple decades and includes various types of EMF sources including cell phones, WiFi, power lines, and other common sources of electromagnetic radiation.
86% of the 413 studies examining cardiovascular found measurable biological effects from EMF exposure. This means that 355 studies documented observable changes in biological systems when exposed to electromagnetic fields. The remaining 14% either found no significant effects or had inconclusive results, which is typical in scientific research where study design and exposure parameters vary.
