CPC A61B 5/316 (2021.01) [A61B 5/364 (2021.01); A61B 5/366 (2021.01); A61B 5/339 (2021.01)] | 18 Claims |
1. A noninvasive electrocardiography (ECG) system for displaying and measuring intervals and segments of an ECG waveform during measurement of the ECG waveform, comprising:
a detector that detects electrical impulses from two or more electrodes located near a beating heart and converts the electrical impulses to an ECG waveform for each heartbeat of the beating heart;
a processor that
converts the ECG waveform for at least one heartbeat from the detector into a plurality of time domain cardiac electrophysiological subwaveforms and discontinuity points between these subwaveforms of the ECG waveform,
compares the plurality of subwaveforms and discontinuity points to a database of subwaveforms and discontinuity points or to a set of rules developed from the database, and
identifies a bundle branches (BB) to J-Point (BB-J) interval from the comparison, and calculates a length of the BB-J interval in time; and
a display device that displays the ECG waveform with the BB-J interval annotated and displays the length of the BB-J interval in time for the at least one heartbeat of the beating heart,
wherein the display device further displays a BB-J interval standard value range for the length of the BB-J interval and, if the length of the BB-J interval is outside of the BB-J interval standard value range, displays the length of the BB-J interval in a different color and sounds an audible alarm.
