Title: Apnoea automatic diagnosis method using ECG signal from patient - determined over longer period from which timed course of heart frequency is computed and evaluated
Inventor: MUELLER PETER
IPC: A61B5/113
Filed: 1991-05-02
Abstract: Time sections are taken for identifying apnoea phases, in whch the heart frequency has no fluctuation of the cycle duration, and the breathing is coming to a standstill.
