摘要： Apparatus for the recognition of ventricular premature beats by an identifying width of a QRS complex by dividing the area by the height and further noting when the width measurements is at least 40% wider than the average width of the immediately preceding several QRS complexes. Additional apparatus for indicating ventricular premature beats by determination of an early width determination which exceeds the average width by at least 20% and is additionally followed by the compensatory pause as determined by interbeat interval measurement.

摘要： An improved R-wave detector is provided for use in monitoring and/or analyzing electrical heart waveforms. Generally conventional R-wave detection means employ automatically variable scaling means for providing a threshold or reference value to a comparator which is variable not only in magnitude but also as a percentage of the average R-wave peak value from which it is derived. An ECG waveform is compared with this threshold of automatically variable percentage value and an indication of R-wave occurrence is provided when the ECG waveform exceeds the threshold. Upon an indication of R-wave occurrence, the percentage value of the threshold is rapidly increased such that a closely following T-wave of unusually large magnitude is not falsely detected as an R-wave. Then, following the interval during which a T-wave might occur and before the possible occurrence of even a premature following R-wave, the percentage value of the threshold decreases to a level capable of detecting even such premature R-waves of reduced amplitude.

摘要： A personal alarm system is disclosed which incorporates a speakerphone so as to permit substantially handsfree operation and remote activation. The system includes a speakerphone which interfaces to a subscriber station. The subscriber station in turn interfaces over a communications link to a central monitoring station which is operative to receive and analyze messages transmitted to the central monitoring station by the subscriber station. Following transmission of a message from the subscriber station to the central monitoring station, the central monitoring station may transmit a control signal to the subscriber station which causes the subscriber station to activate the speakerphone to permit verbal communication with a subscriber who may be immobilized and/or physically unable to initiate a telephone call or answer a telephone. The system further includes an automatic phone answering mode following the activation of a switch by a subscriber, a remote phone answering mode at the subscriber's location, and remote message mode for informing a caller to stand by while the subscriber comes to the phone. In a particular system, some or all operating modes may be employed.
