The invention relates to medicine, cardiology and proctology and directly to the differential diagnosis of cardiogenic myocardial ischemia and anorectal-cardiac brake reflex.

There is a method of differential diagnosis of cardiogenic myocardial ischemia and abdominal-cardiac brake reflex (a variant of which is anorectal-cardiac brake reflex on the background of acute hemorrhoids, thrombosis of hemorrhoids or rectal fissures), namely, that produce electrocardiographic (ECG) study and the ECG changes characteristic of circulatory disorders of the myocardium, diagnosed myocardial ischemia (Bunimovich M. S., Kosatka S. A. About changes in the T wave of the electrocardiogram in acute diseases of abdominal organs //Actual problems of diagnosis, treatment and prevention of internal diseases. - M - MMSI. - 1992. - S. 41-58).

However, in acute hemorrhoids, thrombosis hemorrhoids and anorectal fissure ECG changes can be caused not by the pathology of the heart and implementation anorectal-cardiac brake reflex due to the transmission of pathological activity on the background of pronounced pain syndrome to the heart, which leads to reflex spasm of blood vessels of the myocardium and ischemia. At the same time, the pathology is erektilnoy it, but its implementation in the form of development anorectal-cardiac reflex need confirmation, because in the presence of cardiac pathology question about anesthesia ensure operations can be severely compromised. In this case the error in diagnosis complicates the definition of tactics of treatment of the patient and the option of anesthesia, which leads to a delay in operative treatment of acute surgical pathology of the anorectal region, may threaten the life and health of the patient.

The technical objective of the proposed method is to optimize the differential diagnosis of myocardial ischemia due to cardiac pathology, and anorectal-cardiac brake reflex on the background of acute hemorrhoids, thrombosis of hemorrhoids or rectal fissures.

The technical result is achieved in that in the method of differential diagnosis of cardiogenic myocardial ischemia and anorectal-cardiac brake reflex on the background of acute hemorrhoids, thrombosis of hemorrhoids or rectal fissures, accompanied by severe pain, produce ECG recording, and then produce perianal blockade of the anesthetic solution in the amount of 10.0 to 15.0 ml, then after 60-90 min re-record the ECG and the obtained record is compared with the ECG recording, made up of blockages is, with positive dynamics of ECG diagnose ischemia caused anorectal-cardiac inhibitory reflex, and in the absence of positive dynamics - cardiogenic myocardial ischemia.

The invention consists in that the first ECG recording, then perianal blockade of the anesthetic solution in the amount of 10.0 to 15.0 ml, then after 60-90 min to produce a re-recording of the ECG, which is compared with the ECG recording made prior to the blockade, and with positive dynamics of pathological changes on the ECG diagnose ischemia caused anorectal-cardiac inhibitory reflex, and in the absence of positive dynamics - cardiogenic myocardial ischemia.

The method is as follows.

In acute hemorrhoids, thrombosis of hemorrhoids or rectal fissure, accompanied by severe pain, produce the first ECG recording, and then perianal blockade of the anesthetic solution in the amount of 10.0 to 15.0 ml, then after 60-90 min re-record the ECG, which is compared with the ECG recording made before the siege, and in the presence of positive changes on ECG diagnosed with myocardial ischemia due to anorectal-cardiac inhibitory reflex, and in the absence of positive dynamics of ECG - cardiogenic myocardial ischemia.

How different is the real diagnosis of cardiogenic myocardial ischemia and anorectal-cardiac brake reflex was used in 23 patients with chest pain and signs of myocardial ischemia on the ECG in acute hemorrhoids, thrombosis of hemorrhoids or rectal fissure on the background of pronounced pain syndrome. Of these, 19 patients were found to have myocardial ischemia, caused anorectal-cardiac inhibitory reflex, and 4 - myocardial ischemia due to cardiac pathology. Diagnostic with no errors.

Example. Patient K., 57 years have complained of intense pain in the anus, where it was determined at 3 and 6 hours external thrombosed hemorrhoids size of 2.2×1.8-and 2.5×2,6 see it was also noted moderate pale skin, sweating, pain in the chest cramping compressive nature, palpitations. ECG marked ST segment depression and pronouncedly negative the T wave, single and multiple polytope extrasystoles, tachycardia and tachyarrhythmia. For the differential diagnosis of cardiogenic myocardial ischemia and anorectal-cardiac brake reflex was produced perianal blockade of 1.0% solution of novocaine in the volume of 15.0 ml After blockade of local pain in the anus disappeared, and chest pain and heart attacks regressed. The control electrocardiogram within 1 hour after the siege marked regression of all pathological ECG changes, coupled with the complete disappearance of clinical symptoms has allowed is to exclude cardiogenic myocardial ischemia and further to perform surgery under local anesthesia.

Additional symptoms consider new and significant, in order to enhance the differential diagnosis of cardiogenic myocardial ischemia in the pathology of the heart and anorectal-cardiac brake reflex on the background of acute hemorrhoids, thrombosis of hemorrhoids or rectal fissures.

The method of differential diagnosis of cardiogenic myocardial ischemia and anorectal-cardiac brake reflex, namely, that on the background of acute hemorrhoids, thrombosis of hemorrhoids or rectal fissures, accompanied by severe pain, including ECG recording, followed by perianal blockade of the anesthetic solution in the amount of 10.0 to 15.0 ml, then after 60-90 min re-record the ECG and the obtained record is compared with the ECG recording made prior to the blockade, with positive dynamics of ECG diagnose ischemia caused anorectal-cardiac inhibitory reflex, and in the absence of positive dynamics - cardiogenic myocardial ischemia.

SUBSTANCE: group of inventions relates to medical equipment. In the method realisation ECG graphs and graphs of tracks of coordinates of the heart electric activity source are built in the system of coordinates, connected to electrodes on the patient's body. After that, the time "zone of beginning" of a P/Q impulse is identified. In the "zone of beginning" a time ECG track is approximated and an intersection of an approximated curve with an isoline is found to determine the time moment of the point of P/Q "beginning". The determined time moments of the "beginning" points are transferred onto an initial track of impulses. The origin of the myocardium coordinate system is transferred into the determined point P of the track. Coordinates of the sinus node of the myocardium SU are tied to the track origin for the complex P, and those of the interventricular septum IVS - to the track origin for the impulse Q. The device for the method realisation contains an electrocardiograph, a unit for the identification of the time area of the "beginning" of the impulse P/Q, a unit of fixation of the "beginning" point on the graph of the tracks and a unit of transfer of the primary system of coordinates into the myocardium coordinate system.
