Abstract
Disclosed is a heart beat waveform monitoring apparatus for electronically analyzing the heart beat of an individual to recognize the unique characteristics of pre-ventricular contractions and other abnormalities of the heart beat rhythm, The device can detect and warn of the presence of tachycardia as well as prevent false indications of a "heart attack" due to noise. Logic circuits are provided to detect the characteristics of the abnormalities and to actuate an indicator.
Claims7
Heart beat waveform monitoring apparatus for detecting heart beat waveforms by transducers secured to a patient and for analyzing the waveforms for abnormalities, the apparatus comprising:
- first logic means for sensing presence of a QR rise in as heart beat waveform and producing a pulse responsive thereto;
- second logic means for sensing presnce of an unusually wide QRS heart beat waveform and producing a pulse responsive thereto;
- first AND gate means for receiving pulse signals from said first and said second logic means and passing an output pulse upon coincidence of said signals;
- other logic means for detecting absence of a heart beat waveform following a first heart beat waveform and producing an output pulse responsive thereto;
- second AND gate means for receiving output pulse signals from said first AND gate means and said other logic means;
- and
- indicator means connected to said second AND gate means to be activated upon receiving a signal from said second AND gate means.

- second logic means for sensing the presence of an unusually wide QRS heart beat waveform and producing a signal responsive thereto;
- third logic means for sensing the absence of a pulse within a predetermined time following said signal generated by said first logic means, and passing a signal;
- and
- And gate means for receiving said signals and passing an output signal when said signals are received in coincidence.
