<p>Arrhythmia Recorder A device for recording and subsequently reproducing information, such as desired portions of an ECG signal produced by a heart prior to and during the occurrence of a disturbance in cardiac electrical activity. The device may be used to monitor the operation of an automatic implantable defibrillator. The inventive device takes the form of an external recorder external electrodes for associating with the patient; ECG information is transmitted to the recorder unit by telemetry. A delay-type continually updated memory is continuously operative. When any one of several types of arrhythmias is sensed, or when a defibrillating pulse is delivered by the implantable defirbillator, the data in the memory is "permanently" recorded on magnetic tape.</p> |
