ABSTRACT:
A device is used for determining pulses changed as to form of a pulse sequence, particularly width-widened extra systoles in an electro-cardiogram. The device is particularly characterized by a filter arrangement for separating out frequency parts characterisitic for the form and time properties of pulse sequences from the energy frequence spectrum of the sequence. The device also includes means for evaluating the obtained frequency parts to provide pulse identification.
