An important discovery for the development of electrocardiography was the fact that various diseases of the heart muscle form differs from the normal ECG. The very heart of the language of the instrument sends a signal SOS - a person in danger, take action!
And here, at the forefront of the struggle for human health, electronics, she confidently takes place in the same ranks with the physiology and medicine, as their staunch ally.
Just finished a complicated heart surgery. Switch off the device; monitor the condition of the patient on the operating table, and television equipment, which allowed doctors to monitor dozens of confidence motions known surgeon during the operation unique. A regular battle for life. But the doctor knows - this is not a victory. After elimination of ventricular sepal defects may be damaged pathways fiber bundle-branch block. Then - disaster. To prevent it, it was necessary to create a device that allows you to clearly and quickly identify the conduction system fibers in the thickness of the myocardium, the problem is quite complicated, considering that the bundle of fibers has a width of 1 mm and runs at a depth of about 3 mm. However, such a device - bundle branch locator - was created. According to the principle of it like mine detector and allows us to find conductive fibers, using their superior conductivity compared with other tissues surrounding the bundle of His. Changing the impedance of the tissue under a thin gold electrode causes the detuning of one of two RF generators, resulting in a headphone signal appears low tone, indicating that the conductive beam is detected.
