Description

Изобретение относитс  к электроизмерительной и импульсной технике и мбжет быть использовано в меди,цинской технике дл  измерени  интервала PR электрокардиосигнала.The invention relates to electrical measuring and impulse technology and can be used in copper, the Chinese technical technique for measuring the PR interval of an electrocardiogram.

Известно устройство, содержащее формирователь, измеритель временного интервала, схему разрешени  жлдачи результатов 1..A device is known that contains a driver, a time interval meter, a scheme for resolving the result field 1.

Однако известное устрсЛство не обеспечивает необходимой точности измерени  интервала PR.However, the known device does not provide the necessary accuracy of measurement of the PR interval.

Наиболее близким по технической сущности к изобретеншо  вл етс  устройство дл  измерени  интервала PR электрокардиосигнала, содержащее пороговый элемент, два последовательно соединенные мультивибратора, последовательно соединенные генератор, логический элемент И, счетчик и регистр 21.The closest in technical essence to the invention is a device for measuring the interval PR of an electrocardiogram, containing a threshold element, two serially connected multivibrators, serially connected oscillators, logic gates And, a counter and a register 21.

Недостатком данного устройства .  вл етс  то, что импульсные помехи, превышающие порог срабат вани  в пороговом элементе, создают ошибки в определении величины интервала PR.The disadvantage of this device. is that impulse noise, exceeding the threshold in the threshold element, creates errors in determining the value of the PR interval.

Цель изобретени  - повышение помехозащищенности при измерении интервала PR электрокардиосигнала путем анализа длительности сигнала.The purpose of the invention is to improve the noise immunity when measuring the PR interval of an electrocardiogram by analyzing the signal duration.
