Abstract
Abstract A method and apparatus for detecting and responding to herald signs in the cardiac waveform, such as a fast heartbeat rate, a low rate or a skipped heartbeat. In one embodiment the detection of a herald sign causes the ECG waveform to be transmitted to a remote location where it is analyzed and a signal retransmitted to the patient triggering an alarm or causing other appropriate action. In another embodiment, the detection of a herald sign causes the ECG to be recorded on a loop of magnetic tape or a modular solid state memory device in the unit so that the tape can be replayed and acoustically coupled to the telephone line after the patient calls the central facility. In yet another embodiment, the detection of different herald signs causes different alarm signals, e.g., colored lights, different alarm signals identifying the abnormality, to be operated to indicate to the patient what medication he should administer to himself or whatever other action he should take in the event that communication with central facility cannot be immediately achieved.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
221 words
An apparatus for detecting potentially dangerous herald signs in a cardiac waveform of an individual comprising: means for detecting the cardiac waveform and producing a signal representing that waveform, means for receiving said representing signal, producing a first output signal when the heartbeat rate is less than a first given rate and producing a second output signal when the heartbeat rate is greater than a second given rate, means for receiving said first output signal and producing a light of a first color to the individual that the rate has been determined to be less than said first rate, means for receiving said second output signal and producing a light of a second color different from said first warning signal and indicating to the individual that the rate has been determined to be greater than said second rate, means for receiving said representing signal, said first output signal and said second output signal and for recording said representing waveform for a given time after receipt of either said first output or second output signal, means for transmitting the recorded signal, to a remote facility after said herald sign is detected, and means for receiving said first output signal and said second output signal and producing an audible noise whenever either said first color light or said second color light is produced.
Claim 2
Independent Claim
221 words
An apparatus for detecting potentially dangerous herald signs in a cardiac waveform of an individual comprising: means for detecting the cardiac waveform and producing a signal representing that waveform, means for receiving said representing signal, producing a first output signal when the heartbeat rate is less than a first given rate and producing a second output signal when the heartbeat rate is greater than a second given rate, means for receiving said first output signal and producing a light of a first color to the individual that the rate has been determined to be less than said first rate, means for receiving said second output signal and producing a light of a second color different from said first warning signal and indicating to the individual that the rate has been determined to be greater than said second rate, means for receiving said representing signal, said first output signal and said second output signal and for recording said representing waveform for a given time after receipt of either said first output or second output signal, means for transmitting the recorded signal, to a remote facility after said herald sign is detected, and means for receiving said first output signal and said second output signal and producing an audible noise whenever either said first color light or said second color light is produced.
