DEVELOPMENT OF A PACEMAKER MONITOR WITH CARDIAC SIMULATOR

Terry O. Steiner · 1975

The system provides continuous monitoring of pacemaker output and simulates normal cardiac activity at the pacemaker leads using fiber optics for electrical isolation. The monitor presents a resistive load of approximately 1000 ohms that drops to about 500 ohms when the LED fires during a pacemaker pulse. The entire system was successfully tested at 26.6 MHz and near RF emitters from 200 to 3000 MHz, and the simulator addition did not affect the pacemaker threshold.

MICROWAVE BIOEFFECTS, CURRENT STATUS AND CONCEPTS

Przemyslaw CZERSKI, Stanislaw SZMIGIELSKI · 1975

The review explains that microwave bioeffects data come from animal experiments, model studies, and epidemiological research on occupationally exposed persons. Animal experiments are divided into acute high dose and chronic low dose exposures, with high dose effects explained by non-uniform deep body heating. Chronic exposure effects, especially frequency and modulation dependent effects in the nervous and hematopoietic systems, cannot be explained by thermal considerations alone.

Direct magnetic separation of red cells from whole blood

D. Melville, F. Paul, S. Roath · 1975

Approximately 70% of red cells were retained until the field was turned off, with no evidence of immediate cell destruction. Scanning electron microscopy revealed slight surface abnormalities on a small proportion of filtered cells.

Exposure of Rabbit Erythrocytes to Microwave Radiation

P. E. Hamrick, J. G. Zinkl · 1975

Researchers exposed rabbit erythrocytes to 2450 and 3000 MHz microwave radiation at multiple intensities to test for changes in potassium efflux and osmotic resistance. No significant differences were found between exposed and control cells in potassium efflux, osmotic resistance, or hemoglobin efflux.

Microwave and Infra-red Effects on Heart Rate, Respiration Rate and Subcutaneous Temperature of The Rabbit

The Pacemaker Patient and the Electromagnetic Environment

Nicholas P. DrSmyth et al. · 1974

Only 10 documented cases of EMI affecting pacemakers were found, and none were serious or fatal. The authors concluded that environmental EMI does not constitute an important clinical problem for pacemaker patients at this time.

THE EFFECT OF EPHEDRINE AND CORDIAMINE ON THE OUTCOME OF MICROWAVE AFFECTION OF MICE

V. M. Koldaev · 1974

Researchers exposed albino mice to acute microwave radiation at 62±5 milliwatt/cm² for 11 minutes and to chronic radiation at the same intensity for 20 days at 6 minutes daily. Survival increased one and a half fold with cordiamine treatment. No positive effect of ephedrine was revealed.

Rate Effects in Isolated Hearts Induced by Microwave Radiation

J. L. Lords, C. H. Durney, A. M. Borg, C. E. Tinney · 1974

Researchers exposed isolated turtle hearts submerged in Ringer's solution to continuous 960-MHz microwave irradiation while measuring heart rate and force of contraction. At a total input power of 100 mW, corresponding to an estimated 3.3 mW absorbed by the heart, the average heart rate decreased (bradycardia). The authors concluded that the bradycardia could not be explained by heating because raising the bath temperature increased heart rate. They hypothesized that microwave stimulation of nerve remnants in the heart caused the bradycardia.

Changes in certain protective reactions of an organism under the influence of SW in experimental and industrial conditions

Volkova AP, Fukalova PP · 1974

In laboratory experiments, one group of outbred white rats was exposed to 14.88 MHz short waves at 2,250 V/m for one hour, a second group at 100 V/m for four hours, and a third group served as controls. Workers at a station where field intensities exceeded permissible limits showed two-fold lower phagocytic activity and four-fold higher mouth autoflora, while workers at stations within limits had values within normal ranges.

Radiowave and Microwave Blood Warmers: Comparison with Water Bath Blood Warming Units

Hamid Dalili, John Adriani, Wei T. Wu, Monroe S. Samuels · 1973

Water bath warming to 97±1°F did not alter electrolyte or enzyme levels in banked blood. The microwave warmer caused hemolysis in 35% to 40% of blood samples warmed.
