摘要：A method to detect and identify any cardiac abnormality of a human heart bymeans of the frequency analysis of the cardiac electrical signal of the twelve (12) leads
independently and two (2) corresponding leads jointly, comprises the steps of obtainingfrom a patient 12 time-domain cardiac electrical signals, commonly known as 12-lead ECG(electrocardiogram) signals, mathematically transforming these ECG signals into twelve(12) individual frequency-domain amplitude spectra with one spectrum for each of the 12leads in a frequency range from 0 Hz to 25 Hz, applying the digital signal processprinciples of plurality of functions to determine the quality and quantity of each signaland that of two corresponding signals, comparing against a set of parameters that hasbeen established in advance to identify and determine the diagnostic value of each index,and analyzing the value of all identified indexes thereby assessing the pathologicalcondition of a human heart.
