Abstract. Background/Aim: The aim of this study was to assess the acute effects of physical vascular therapy (PVT) on the autonomous nervous system by heart rate variability (HRV) and heart rate asymmetry (HRA) analysis. The low-frequency, pulsed electromagnetic field (<35 μTesla) with a patented BEMER pattern can improve vasomotion and microcirculation. A non- invasive confirmation of the instant effects of PVT may provide an opportunity to give an immediate feedback to the patient and therapist. Patients and Methods: Altogether 48 patients on inward rehabilitation with coronary heart disease (CHD) were involved, their treatment included PVT with B.Box Professional and B.Body Pro applicator (BEMER International AG, Triesen, Lichtenstein). After 15 min of postural adaptation, 6-min electrocardiograms (ECG) were taken immediately before, in the first and in the last 6 min of the 20-min PVT, and one hour after the treatment. Of the 48 patients, the last twenty patients received sham PVT with the same protocol. Off-line analysis was blinded. We used linear mixed statistical model to compare HRV and HRA parameters. Results: The time domain parameters did not show any statistically significant differences between the changes in the real PVT and sham groups but, in the first stage of the treatment, Porta and Guzik indices significantly rose everywhere
except in the sham group. Conclusion: PVT significantly increases the Guzik and Porta indices in chronic ischemic heart disease patients reflecting a delicate autonomic response. HRA as a measure of autonomic regulation seems to be more sensitive than time domain parameters.

Many ancient civilizations such as the Greeks, Egyptians, Chinese, Mayas, and the Romans were aware of magnetism. They used magnetic stones for relieving pain, preserving beauty and healing. According to ancient writings, Hippocrates referred to magnetism as "iron-attractive stone". The intention to better understand the properties of magnets began in the 17th century. One of the earliest scientific accounts can be found in a book entitled De Magnete, written in 1600 by William Gilbert, personal physician of the Queen of England (1). Franz Anton Mesmer, who was a German physician, was the first scientist to declare that the magnetic properties of magnets are suitable for healing diseases. Initially, physicians used static magnetic fields (2). The recognition that magnetic fields can be generated by electricity was a great milestone in magnetotherapy. This phenomenon became widely recognized when Hans Christian Oersted conducted a series of similar experiments in 1820 (2). In the middle of the 20th century, there was a growing interest in effective electromagnetic therapy stemming from Japan, and then spreading to Europe. The therapies which utilize electromagnetic fields, including pulsed electromagnetic fields (PEMF), became more widespread than treatments using static magnetic fields. During the 1970s, Bassett confirmed that PEMF therapy has a positive effect on the healing of bone fractures (3). Furthermore, PEMF therapy seems to have clinical benefits in low back pain according to a recent meta-analysis (4).
