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.
