P WAVE DETECTION METHOD IN ELECTROCARDIOGRAM ANALYSIS, ELECTROCARDIOGRAPH WITH ANALYSIS FUNCTION AND HOLTER ELECTROCARDIOGRAM ANALYSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To enhance P wave and accurately detect it by gaining second differential values of multiple induction electrocardiogram signals and respectively gaining and adding absolute value of second differential calculated signals. SOLUTION: A second differential calculation unit 2 is to respectively gain second differential values of multiple induction electrocardiogram signals output by an amplifier 1. An absolute value calculating unit 3 is to respectively gain absolute values of second differential processed signals. An addition processing unit 4 is to add absolute value processed multiple induction signals. A P wave detection unit 5 is to detect P wave from addition processed signals. A control analysis unit 6 is to analyze the electrocardiogram based on the detected P wave.
