Patent ID: 8897866

Claim:
A process for measuring electrocardiography (ECG) based on multi-point touch on a display screen comprising the following steps: a. Collect ECG data with an acquisition device, or by scanning ECG report, or by drawing on the screen; b. Two fingers touch two points simultaneously on the screen, which projects two target points on waves of the ECG which is loaded on the screen; c. Generate a horizontal baseline and a vertical baseline between the two target points, and calculate the horizontal interval (x) in milliseconds and vertical interval (y) in microvolt between the two target points; d. Move the fingers and project two new target points, update new baselines and new intervals between the two new target points; e. Repeat steps b. c. and d. to measure the intervals for different positions of the waves of the ECG including wave top point, wave beginning point and wave ending point; f. Analyze acquired data from above steps to diagnose heart abnormalities or to study cardiology wherein the two touch point coordinates are designated as (x1 , y1) and (x2, y2); the x1 and x2 divided by pixelsPerPoint results in point index n1 and n2, respectively, through which the voltage values on y axis from voltage[ ]array are v1 and v2 , which yields two target point coordinates designated as (n1, v1 ) and (n2, v2 ), wherein pixelsPerPoint represents pixels per point on screen; then drawing the two target points on the screen based on the pixels per point.
