A portable apparatus for recording and analyzing electrocardiogram comprises means for counting the sum of P, Q, R, S, T and U waves that are greater than a setpoint reference voltage of ECG waves for every predetermined period of time, means for storing the previously counted value, means for setting a reference value of difference between the above two means, signal means which produces a signal when the difference between the counted value of said counting means and the stored value of said storage means is greater than a predetermined value, recording means for recording ECG waves during any discrete time, and means which, when said signal means produces an output, stores the ECG waveforms at that moment together with the ECG waveforms of the preceding stage. The apparatus is adapted to monitoring patients who are treated for their disease of the heart and trouble in the brain, monitoring mentally and nervously diseased areas, monitoring patients who are being treated in a hospital or in their own homes, and monitoring the life of a severely wounded person. |
