Definitions
- the invention relates to a diagnostic system in which, in a long-term registration, measured values from the esophagus of a patient and his heart rate variability are determined to determine the state of the patient's autonomic nervous system.
- motility disorders The study of motility disorders is currently being carried out by means of the methods of manometry, impedance measurement in the esophagus for the representation of an orderly transport and by the pH-metry for the preparation of acid reflux. This can also be symptom-related to detect the involvement of motility disorders in the symptoms.
- the involvement of the autonomic nervous system plays a significant role in the function of the system, modulating the functions of the individual muscle groups, influencing the otherwise independent nervous system of the digestive tract via the sympathetic and parasypathic nerves enteric nervous system, is taken. If one wants to enable a more extensive investigation of the cause of the malfunction, it is essential to record the activities of the autonomic nervous system.
- the activity of the autonomic nervous system can not be readily measured directly, but there are some non-invasive options available: skin conductance measurements, blood pressure measurements, pupil response, respiratory rate measurements, or, most particularly, heart rate variability.
- skin conductance measurements skin conductance measurements
- blood pressure measurements blood pressure measurements
- pupil response pupil response
- respiratory rate measurements or, most particularly, heart rate variability.
- heart rate variability In addition to the performance-related heart rate, there is a further influence on the heart rate due to mental stress, which can be demonstrated by recording the heart rate variability.
- the simultaneous recording of the heart rate variability is used for the assessment of the causes of the symptoms, this may decisively change the decision for a form of therapy.
- the heart rate variability is preferably detected by detecting the change in the time between two heartbeats, usually represented by the so-called R wave, from the heartbeats derived by means of an ECG and being presented in a suitable form with the other acquired data.
- the representation can be represented as a simple derivation of the temporal courses or as a frequency spectrum.
- probes for detecting motility data in the esophagus are known.
- Measuring catheters for determining impedance values, pH values and pressure values and the combination of such a measuring catheter with a patient ECG derived simultaneously are known, for example, from US Pat. No. 4,503,859 A and DE 38 36 349 A1. From these writings, however, there is no indication that the activity of the autonomic nervous system may be responsible for determining the cause of a motility disorder and derive the activity of the autonomic nervous system from the ECG.
- the object of the invention is to provide a diagnosis which is suitable for clarifying nonspecific pain in the upper abdomen and thoracic region and to investigate an underlying motility disorder of the esophagus for a connection with the state of the autonomic nervous system.
- a diagnostic system for the simultaneous long-term recovery of heart rate variability and pressure and impedance data from the esophagus of a patient the a suitable for the derivation of the electrocardiogram probe system, a catheter for insertion into the esophagus of the patient, the catheter each having a plurality of probes for pressure and impedance measurement, a recording device with a voltage source and a plurality of channels for registration and recording of the measurement probes originated from the measuring probes and at least one memory for time-dependent storage of the measured data and
- the diagnostic system has multiple probes for manometry and impedance measurement. It may have other measuring probes, for example, to determine the pH and other data.
- the diagnostic system according to the invention is designed so that it can simultaneously record and record an electrocardiogram and the data relevant for the diagnosis of motility disorder.
- two parallel examinations can be carried out which are suitable for diagnosing a possible influence of the autonomic nervous system on motility disorders on the basis of the heart rate variability.
- ECG electrocardiogram
- the derivative can also be done on the extremities or directly in the esophagus. It can be bi- or unipolar.
- the catheter in particular nasal catheter, has a plurality of measuring probes for determining the impedance.
- the impedance measurement makes it possible, in particular, to detect movements of masses in the esophagus, which can not be detected via the pH electrodes, based on the change in the electrical conductivity. This is especially true for the entry of low-acid gastric contents into the esophagus - in this case, the typical symptoms of acid bumping and heartburn remain. At the same time, however, anomalies in drinking and swallowing, peristalsis, can be diagnosed and recorded.
- ring electrodes are used for the impedance measurement, which are applied around the catheter.
- Such ring electrodes are known per se.
- the diagnostic system according to the invention additionally has a plurality of pressure sensors. With the help of the so-called esophageal manometry, the diagnosis of coordination disorders and the measurement of the pressure conditions of the esophageal musculature is possible, above all during swallowing or painful passage of food into the stomach. In particular, malfunctions of the sphincter muscles can also be diagnosed.
- a catheter is used, preferably a nasal catheter, which usually causes the patient little discomfort.
- a nasal catheter can have a very small diameter, for example 1, 5 mm, so that it does not interfere with the food and fluid intake practically.
- the nasal catheter is preferably equipped with at least one, usually two pH-sensitive electrodes, one of which is located about 5 cm from the distal end of the catheter.
- the distal end of the catheter is the end facing inside the body, as opposed to the proximal end facing the recorder which serves to guide the connection between the probes and the recorder, unless telemetric data transmission is performed.
- the catheter is placed so that a pH measuring point is about 5 cm above the cardia.
- the location on the catheter can be arbitrary. Actually existing catheters often have a reference electrode at the distal end, and the measuring point is above it.
- a second pH-sensitive probe may be located at the distal end of the catheter, causing it to regularly come into contact with the gastric acid itself and take a comparative reading there. In general, however, this second pH probe will be located proximal to the first probe and will provide a reading in the middle or upper part of the esophagus. There may be more than two pH-sensitive probes to determine the pathway of the esophageal reflux bolus.
- the pH-sensitive probes are common glass, ISFET or antimony electrodes, as they have long been used for pH registration in the body.
- the recorder is calibrated with respect to the pH measurements, if pH probes are present, that is, it is adapted to the type of probe and the age of the probe, respectively. It is known that the measurement characteristics of pH probes change with age and frequency of use and therefore require calibration.
- the calibration and / or the measurement temperature can be set on the recording device.
- the pH electrodes are reliable to detect the penetration of acidic gastric contents into the esophagus.
- system according to the invention can also have one or more EMG probes with which intraesophageal muscle actions can be recorded independently of the pressure generated.
- the catheter may also have a probe for the detection of enzymes, as they are secreted in particular in the small intestine or duodenum.
- This "small intestinal juice” also frequently exits the small intestine into the stomach and can enter the esophagus with the reflux mass. These are highly effective digestive enzymes, which can further damage the already severely damaged mucosa of the esophagus.
- the system according to the invention can also have, alternatively or cumulatively to the measuring probes for the ECG, those for an EEG, in particular those for the derivation from the cortex.
- the recording device itself has a conventional voltage source, such as a battery or a rechargeable battery, and the necessary channels for registration and recording of the measured data. Furthermore, in addition to at least one mass memory, preferably a memory card, there is an additional memory for programming the device functions for the time-dependent storage of the measured values.
- the system has the necessary connections between the recording apparatus and the probes for power supply and data transmission. It is expressly pointed out that data transmission can also be wireless (telemetric), for example via RFI D systems. Means for data transfer between probes and Recording device are thus all suitable for signal transmission connections, whether they are via lines or wirelessly.
- conventional recording devices can be used to record the measured data, as they are often described in the literature.
- a recording device should, in addition to a permanent memory for the measurement program, have separate memory cards for recording the ECG on the one hand and the measurement data from the esophagus on the other hand. These memory cards can be read and evaluated at the end of the examination on a conventional PC, then reconfigured for the next patient.
- the recorder should also be programmable in terms of time duration and / or time intervals of the measurements. This is especially true for the periods over which the cardiac function is recorded, with significantly more data than for the occasional readings from the esophagus from time to time. For esophageal pH data, it is usually sufficient to take a value every 4 to 20 seconds; impedance measurements are typically recorded at 50 measurements per second.
- the recording apparatus is preferably also adjustable to the respective measuring probe type, i. The characteristics of conventional measuring probes are stored in the recording device and can be retrieved at any time for fast connection.
- the system according to the invention allows a parallel diagnosis of heart rate variability and thus the activity of the autonomic nervous system and to a comprehensive diagnosis of the processes in the esophagus of a patient over a longer period, for example 24 hours, but also longer.
- the arrangement of a plurality of probes in the esophageal catheter allows not only the detection of penetrating into the esophagus masses, but also the determination of the direction of movement and, where appropriate, the behavior of the esophageal musculature. Especially it is possible to measure the direction of transport and the height up to which the reflux rises.
- the reflux can be determined independently of its acidity.
- the invention further relates to the use of the above-described diagnostic system for the simultaneous long-term registration of heart rate variability and of pressure and / or impedance data from the esophagus of a patient in the diagnosis of motility disorders influenced by the autonomic nervous system.
- this allows differential diagnosis of motility disorders caused by the autonomic nervous system and those that are organically conditioned, for example gastroenterological causes.
