32 healthy students (18 women and 14 men) with normal electrocardiogram and echocardiogram at rest participated. ECG recordings were performed on sitting subject in a semi-darkened, quiet room between 8:00 and 9:00 in the morning.
semi-darkened, temperature-controlled quiet laboratory at room temperature (21°C)
Setup
The GSMmobile phone was held in the right hand during the call. It was switched on during the whole time of the experiment so that the effect of logging into the mobile phone network on the maximal emission of EMF could be avoided.
Additional info
Recordings were made over three 20 min periods, i.e., before, during, and after the telephone call.
