Problems solved by technology

However, this approach is generally not applicable to existing ECGs, nor is it suitable for retrospective analysis on a central server of acquired data that has been low-pass filtered at 150 Hz and stored at a sampling rate of 500 sps
The fact that typical ECG processing systems apply a 150Hz low-pass filter to the ECG signal and store it at a sampling rate of 500sps generally makes retrospective biV pp detection more difficult

Embodiment Construction

[0021] The foregoing and other forms of the invention, as well as various features and advantages of the invention, will become more apparent from the following detailed description of various embodiments of the invention read in conjunction with the accompanying drawings. The detailed description and drawings are merely illustrative of the present invention, rather than limiting, and the scope of the present invention is defined by the appended claims and their equivalents.

[0022] As mentioned above, an increasing number of patients with chronic heart failure are receiving CRT. CRTs pace the left and right ventricles at adjustable intervals to maximize cardiac output. Due to the evolving CRT market, identifying biventricular pp on surface ECG can be a critical issue for automated ECG analysis systems and methods. Existing known methods often require high sampling rate hardware. Rather, the present disclosure describes, for example, a novel system and method to detect bive...

Abstract

A system for locating the existence of a biventricular pace pulse for ECG, which includes a non-biventricular pulse detector for finding the onsets of ventricular pulses, a lead-wise biventricular pulse detector for checking whether there are two separated ventricular pulses in one heartbeat, and a vector-based biventricular pulse detector for determining the existence of the biventricular pace pulse if the lead-wise biventricular pulse detector does not find that there are two separated ventricular pulses in one heartbeat.

Description

technical field [0001] The present disclosure relates, for example, to medical systems, methods and devices, and more particularly, to novel and inventive systems and methods for biventricular pacemaker pulse detection in body surface ECG. Background technique [0002] An increasing number of heart failure patients are receiving cardiac resynchronization therapy (CRT), which uses pacing of the left and right ventricles to maximize cardiac output. Asynchronous biventricular (biV) pacemaker pulses (pp) in surface electrocardiogram (ECG) waveforms pose a challenge to in silico diagnostic ECG analysis algorithms. For example, pulse detection algorithms that were not designed to identify non-synchronous biV pulses may fail due to closely separated biventricular pulse pairs, and undetected and unresolved pulses may therefore be critical for automatic diagnosis of rhythm or morphology in ECG algorithms. Interpretation has adverse effects. On the other hand, being able to recogniz...
