DE2717883A1 - Cardiological investigation system with bicycle ergometer - has monitor and recorder systems for electro-cardiogram of pedalling - Google Patents

Abstract

The loading phase of patient pedalling the apparatus is covered continuously and a continuous record is produced. The procedure can be carried out in the absence of qualified medical personel. The monitor for reproduction of the electrocardiogram is arranged close to bicycle type ergonometer. It also has a recorder for recording the last section of the electrocardiogram and arrangement for reproducing them on the monitor. This reproduction can be carried out, e.g. for forensic purposes. A graphic record can also be made. The output to monitors can be connected to several monitors if required.

Description

System for cardiological load monitoring

The invention relates to a system for a cardiological stress test, in the case of an EKG recording of a patient loaded with a bicycle ergonometer is carried out.

Cardiac exercise exams have proven to be routine exams also introduced in general practices.

In this case, an EKG is usually written on a piece of paper, which will later be evaluated by the doctor.

However, it has been shown that such examinations are beneficial to the patient may be associated with an appreciable risk. Under the burden respectively.

In any case, it occurs more frequently shortly after exercise Incidents e.g. to Pxtrasystolen, Kanimerflicker or the like. Such incidents require immediate medical intervention. On the other hand is the presence of the doctor Usually neither necessary nor feasible during a load test. In general, such examinations are therefore carried out by appropriately trained personnel Helpers carried out.

The previously known systems of the type mentioned exist usually from the bicycle ergometer, the electrodes to be placed on the patient and the actual EKG device, which receives the signals from the electrodes implements and describes the mentioned paper strip. If there is an incident it often takes too long to get to the patient because of the absence of the doctor medical help can be provided. There is also another disadvantage, which is from the time difference between stress or EKG recording and possible incident results. The EKG recording is only available during a relatively short one temporal fraction of the load made to a written strip to gain sufficient brevity so that the EKG can still be evaluated. Comes if there is an incident outside of the EKG recording, then the incident is itself not documented, so that later verifiable statements about Art and not having an incident repaired.

The object of the invention is to create a system the monitoring and complete documentation of cardiological stress examinations in the stress phase, but here the presence of the doctor in the immediate vicinity of the patient and thus his exclusive Eliminates preoccupation with monitoring the patient as well as that Continuous recording of the ECG on the usual writing strip.

According to the invention, this object is achieved by at least one Monitor set up away from the bicycle ergonometer for displaying the EKG image as well as a recorder with a tape loop for recording the last one Section of the EKG in its reproduction on a monitor enabling signals.

The at a considerable distance from the Falirradergonometer, e.g. in A monitor that can be set up in a doctor's treatment room enables remote monitoring of the patient and has the advantage that the examining doctor the safety of his Enable patients, but can also save time. The recorder documents the last phase of the load test depending on the length of its belt loop, because the recorded ECG can later be played back on a monitor as often as required can be. Such an EKG is particularly suitable for hospital admissions and also for forensic purposes.

The details, other features, and other advantages of the invention result from the following description of an exemplary Ayführungfor based on the figures in the drawing. The drawing shows schematically in the form of a Diagram showing the structure of a system according to the invention.

A hyperbolic, shown schematically at 1, is used for loading, i.e. speed-independent bicycle ergonometer. The patient receives two electrodes 2 or 3, which work on channel 4. A single-channel monitor 5 is placed directly next to Ergonometerplatz 1. According to the illustrated embodiment the monitor 5 is combined with a defibrillator. The output 6 of the with the Defibrillator comes with a combined monitor 5 can be used on any other monitors transfer.

According to the illustrated embodiment, the output 6 goes first to an adapter 7 with three outlets: One of the outlets is labeled 8 and leads to the usual EKG writing implement q, which supplies the strip of paper that will be used later to be evaluated by the doctor kami. 2, in another outlet 8a leads to a line 10, which branches out at 11 and leads to a total of three remote monitors 12-14, of which the latter monitor is shown in dashed lines, in order to make it clear that the system is extended around this. or less ## nitor # n leaves.

The monitors 12-14 are otherwise of the same construction, see above that it is sufficient to explain one of these monitors in more detail below.

The monitors 12-14 are located anywhere and at a distance from that Ergonometer place 1 set up place. For example, such monitors can be in The treatment rooms of different doctors are set up with other examinations are busy and simultaneously monitor the cardiac stress test at 1.

The ECG image as derived from the patient appears on the monitor is. In addition, each monitor 12-14 has a start-stop button 15. The stop signal goes off Via separate return lines 15a, 15b, 15c to a branch point 16 on one Central return line 17. This return line leads to a cassette recorder 18 and actuates the on-off relay there. The cassette recorder, on the other hand, is connected to one third outlet 19 of the adapter 7 is connected, which via an EKG amplifier 20 at 21 in the device 18 leads.

A return play is made via an outlet 22 from the cassette recorder 18 on the monitor 5 via branch line 24, on the EKG recorder 9 via branch line 25 and the monitors 12, 13, 14 via branch line 10.

The cassette recorder 18 contains an endless tape loop at 27 with a running or recording time of, for example, 30 seconds. It contains also a demodulator, which the pulses from the line 19 for the recorder transforms and amplifies.

The use of a cassette recorder has the advantage that optional also a long-term ECG storage on a corresponding long-term cassette and which can be played on the monitors 12-14.

The system works as follows: Once the patient has the electrodes 2 and 3 have been applied and the stress test begins, the EKG is performed initially reproduced on monitor 5 and also gets over the line 6 and the adapter 7 and via the outlet 10 via the branch point 11 on monitors 12 and 13 resp.

14. The supervising doctor can therefore follow the entire examination or carry out other examinations or activities at the same time. He also has the possibility of stopping the cassette recorder 18 via the start-stop button 15 and to stop further recordings as well as by switching on the on the Tape loop reproduced ECG recording to be transmitted to the monitor 12-14. At the same time, he can switch on the EKG recorder 9 himself via the branch line 22, to record particularly valuable ECG phases.

In particular, every incident can be seen on monitors 12-14, the last phase of which is recorded on the tape loop in the cassette recorder 18 will.

In the embodiment shown, commercially available devices, i.e. monitors, recorders, amplifiers, adapters and cassette recorders are used.

In particular, the cassette recorder 18 can be equipped with a power supply unit 28 as it is also commercially available. The system has the advantage that all monitors the ECG image via the recording made in the cassette recorder can play any oct and the EKG recorder 9 the tape recording in Can hold the shape of the usual paper strip.
