Die EKG-Signale werden dabei meist über einen Zeitraum von 24 Stunden oder länger, in einem elektronischem Speicher z. B. einem RAM, aufgezeichnet und zeitversetzt bzw. off-line über eine Schnittstelle am Monitor des behandelden Arztes ausgewertet. Rythmusstörungen am Herzen sind so nachträglich erkennbar.ECG device systems to be worn on a patient's body have been known for a few years. The ECG signals are usually in one over a period of 24 hours or longer electronic memory z. B. a RAM, recorded and staggered or off-line via a Interface evaluated on the monitor of the treating doctor. Rhythm disturbances at the heart so recognizable afterwards.

Bekanntgeworden ist auch ein EKG-Fernübertragungssystem bei dem die EKG-Signale mittels Tonfrequenzmodulation analog über das bekannte Festnetz-Telefon an einen Empfänger geleitet werden. Dieses System ermöglicht eine zeitnahe EKG-Überwachung eines Patienten, jedoch bei nur eingeschränkter Bewegungsfreiheit und einer zusätzlichen Mithilfe des Patienten durch Anwahl des Empfängers und Einleitung einer Übertragung. Das übertragene EKG entspricht so einerseits nicht dem normalem freien Tagesablauf des Patienten und ist andererseits umständlich handhabbar.Also known is an EKG remote transmission system in which the EKG signals are used Audio frequency modulation analog to a known landline phone to a receiver will. This system enables a patient to be monitored for ECG in a timely manner only limited freedom of movement and additional help from the patient by selection of the recipient and initiation of a transmission. The transmitted ECG corresponds on the one hand not the normal daily routine of the patient and on the other hand is difficult to handle.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die die vollautomatische Online-EKG-Überwachung eines Patienten unabhängig von dessen Aufenthaltsort und ohne dessen Mitwirkung gestattet.

B. D-Netz) ständig online oder im Falle einer vom Gerät erkannten Rhytmusstörung an eine externe Empfangsstation übertragen und dort zeitgleich ausgewertet oder aufgezeichnet werden. Rhytmusstörungen werden so rechtzeitig erkannt und können dem Patienten signalisiert werden. Bei bedrohlichen Rhytmusstörungen kann so rechtzeitig der medizinische Notdienst alarmiert werden. Zwischenzeitliche Arztbesuche sind ebenfalls nicht mehr erforderlich und der Patient kann sich während der Aufzeichnung und während einer Übertragung frei bewegen.This object is achieved in that a wearable on the body of a patient ECG device with the main modules AD converter, RAM memory, microcontroller, with one Telephone circuit and a transceiver circuit of a cell phone for a radio network is connected so that the digitized signals of the cardiac output curves of the AD converter both in the RAM memory of the EKG device, as well as online via a radio network (e.g. D network) or in the event of a rhythm disturbance detected by the device to an external receiving station transferred and evaluated or recorded there at the same time. Rhythm disturbances recognized in time and can be signaled to the patient. When threatening The medical emergency service can be alerted in good time to rhythm disorders. Intermediate visits to the doctor are also no longer necessary and the patient can relax move freely during recording and during a transmission.

Die Verbindung des RAM-Speichers des EKG-Systems mit dem HANDY-Telefon-Schalt­ kreis gestattet sowohl die Aufzeichnung der EKG-Signale im RAM-Speicher, als auch die gleichzeitige Online-Übertragung zur externen Empfangsstation. z. B. beim Arzt mit digitaler Aufzeichnung und/oder einer echtzeitlichen Auswertung über Monitor oder durch Anschluß eines Druckers.The connection of the RAM memory of the EKG system with the mobile phone switch circle allows both the recording of the ECG signals in the RAM memory and the simultaneous online transmission to the external receiving station. e.g. B. at the doctor with digital Recording and / or a real-time evaluation via monitor or by connecting one Printer.

Findet der Sende- Empfangs-Schaltkreis der HANDY-Baugruppe keinen Anschluß im D-Netz. so erfolgt in festgelegten zeitlichen Abständen über eine automatische WAHLWIEDERHOLUNG eine erneute Übertragung, oder die Übertragung wird automatisch auf eine festgelegte andere Telefon-Nr. geleitet.If the transmit / receive circuit of the HANDY module finds no connection in the D network. so takes place at fixed intervals via an automatic REDIAL a retransmission, or the transfer is automatically set to another Phone number. headed.

Nach erfolgter Übertragung kann der RAM-Speicher vom Empfänger über ein Steuersignal gelöscht werden.After the transfer is complete, the RAM memory can be cleared by the receiver using a control signal will.

Der der Erfindung zugrundeliegende Gedanke wird in einer nachfolgenden Beschreibung anhand eines Ausführungsbeispieles, das in der Zeichnung dargestellt ist, näher erläutert.The idea on which the invention is based is described in the following description of an embodiment, which is shown in the drawing, explained in more detail.
