The effect of AC (50 Hz) electric field (EL) of 80 kV/m on ECG, cardiac output (Q) and arterial pressure (AP) has been studied on 15 rabbits after 60 days of exposure for 8 hr a day and in an equal number of controls (C). Average heart rate value was 272 +/- 27.1 (+/- SD) b/min in C and 266 +/- 23.7 b/min in exposed animals. No alterations of ECG waves was found. Q (thermodilution method) was 234 +/- 22.4 ml/min X kg b.w. in C and 245 +/- 13.9 ml/min X kg in exp. respectively. Mean AP (direct measurement) was 102 +/- 3.5 mmHg and 104 +/- 5.1 mmHg in C and exp. respectively. The difference in the variables studied between the two groups is not statistically significant. In conclusion, chronic exposure at high intensity EL does not seem to affect the cardiovascular variables investigated.
