AI Technical Summary
The accuracy of pulse wave transmission velocity measurement in existing technologies is low, especially in single-point and two-point methods, where there are difficulties in selecting measurement locations and decomposing blood flow waveforms, leading to inaccurate measurement results.
The system employs chest, wrist, and finger signal acquisition devices to collect electrocardiogram (ECG) signals, wrist pulse wave signals, and finger pulse wave signals, respectively. A data processing device combines these signals to calculate the pulse wave transmission velocity. The process includes a chest signal acquisition device collecting ECG and aortic pulse wave signals, a wrist signal acquisition device collecting wrist pulse wave signals, and a finger signal acquisition device collecting finger pulse wave signals. The data processing device then performs comprehensive calculations.
The accuracy of pulse wave velocity measurement has been improved. By comprehensively considering multiple signals and dynamically constructing a generalized transfer function model, errors caused by peak correspondence errors and vascular changes have been reduced, resulting in more accurate pulse wave velocity measurement.
