Abstract

This invention is a medical technique, more specifically, for ECG registration devices, to perform heart stimulation and defibrillation through the oesophagus.The foundation of the stylet is a flexible conduit (3), which has a distal pole (1) and separate metal rings (2) connected with separate insulating wires to the socket of the connection log.

Description

The present invention relates to the field of medical technology, more particularly to a group of devices for recording ECG and for stimulating and defibrillating the heart through the esophagus.

Known esophageal probe / which consists of central? a tube with two rings and a retainer at the distal end extending radially (U.S. Patent No. 4,640,298, A61N 1/04).

the disadvantage of this probe is that it can and can be performed. if the heart is not fit for heart defibrillation only has 2 rings of stimulation. It performs neither. ECG

Also known is an esophageal defibrillator electrode for performing esophageal defibrillation. It has a probe with an electric cable internally and a contact portion at the end of the probe consisting of 2 parts, between which is a ring-shaped electrode which is connected to an electrocardiograph by insulated conductors (SU a.l. No. 439292, A61N 1/04). '- /' / '/; //' '

The disadvantage of this esophageal electrode is that it is uncomfortable to use due to its coarse construction and also has limited functional capabilities as it is only suitable for esophageal ECG recording and defibrillation through the esophagus. Replacement of the electrode is required for transplanar defibrillation, -. this is inconvenient for the patient and prolongs the procedure.

The object of the invention is to simplify the construction of the probe and to expand its application possibilities.

The objective is achieved by the fact that the contact part of the known 35 electrode having insulated output wires is composed of individual metal rings with a good contact surface area.

The probe consists of a distal end '1, individual metal rings 2,' mounted on a flexible insulating tube 3, which has insulated wires74 / which 'connect the surfaces of the metal rings to the sockets 5 of the connection pads. . ; ·

The probe is used as follows: the patient or subject is injected orally into the esophagus at the heart level. When the probe is inserted, the contact surfaces of the individual rings are connected to the electrocardiographic derivative plates to determine its position in the esophagus. Multiple monopolar and esophageal ECG derivatives can be recorded simultaneously from individual rings of the contact surface at different depths of the esophagus. From the recorded shape and amplitude of the esophageal ECG p-tooth, we determine the 'optimum position of the individual probe rings' in the esophagus. Optimal ring position »left - atrial level - with maximum amplitude recorded on .stemplary ECG. 25 and biphasic P tooth. This corresponds to a depth of 32 to 35 cm from the frontal moths. In addition, we clarify the nature of the cardiac arrhythmia from the esophageal ECG.

- We eliminate the right atrial flutter and sbpfavėiitricular paroxysmal tachycardia by rapid atrial stimulation.

For rapid atrial stimulation, we determine the optimum position of the probe rings (per P · tooth) in the esophagus and connect the contact surfaces of the two rings to the stimulator leads.
