History and reason for admission: A 44-year-old man had anginal-like compla
ints. He was convinced that cardiac problems had been caused by electromagn
etic fields.
Investigations: Apart from hypertension and hyperlipidaemia there were no o
ther significant findings. ECG, ergometry Holter-ECG were normal.
Experiment: We tried to verify with a doubleblind provocation test if the p
atient's complaints had been caused by electromagnetic fields. The patient
was exposed to an electric instrument without being aware whether it: was s
witched on or off. He wase questioned about his perception of the presence
of an electric current.
Conclusion: The results of the test showed that there was no causal relatio
n between the patient's angina-likesymptoms and electromagnetic fields. The
phenomenon of electrosensitivity was probably caused by psychological mech
anisms.
