Abstract
A method for alerting patients with diseases affected by climate, such as epilepsy and myocordial infarction, according to which sinusoidal spheric pulses having a frequency of 28 kHz and sinusoidal spheric pulses having a frequency of 10 kHz are measured by a spheric selector circuit. The pulse rate of these spheric pulses is ascertained over a predetermined period of time and the difference between the pulse rates of the spheric pulses at 28 kHz and those at 10 kHz is ascertained. If the spheric pulses having a frequency of 28 kHz predominate, then the patient is alerted by means of a signal generated by a circuit which includes the spheric selector circuit for carrying out the method.
