Clinical Validation of a Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System

Summary

This is a open-label, randomized, paired design, multicenter study of the Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System (R6000) for evaluating cardiovascular autonomic neuropathy. R6000 is novel intellectual diagnostic device for cardiovascular autonomic reflex tests and heart rate variability analysis. A total of 85 subjects will be enrolled in trial Ⅰ and 150 subjects will be enrolled in trial Ⅱ. In trial Ⅰ, subjects will be randomized to two groups, one of which will receive test by the tested device first and the other one will be tested by conventional blood pressure kit. The primary objective of this clinical trial is to evaluate the effectiveness of the Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System. The secondary objective is to evaluate the safety of the cardiovascular autonomic testing system and stability.

DEVICE

Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System (Model: R6000)

Cardiovascular autonomic reflex tests (CARTs) and heart rate variability analysis (HRV) are conducted with Cardiovascular Autonomic Nervous Function Multi-Parameter Evaluation System (Model: R6000). CARTs include five standardized tests, which are heart rate response to lying-to-standing, Valsalva maneuver, deep breathing, and blood pressure response to lying-to-standing and sustained isometric handgrip. These series of movements act as "standardized stimuli" to trigger hemodynamic changes in the body, altering vagal and sympathetic activity through mechanisms such as the baroreflex, thereby producing changes in heart rate and blood pressure. The sensor-monitoring interactive design of the device ensures the standardization of these maneuvers.

Conventional method of CARTs

Conventional method are conduced using blood pressure kit with manual sphygmomanometer and ECG machine. Conventional method and the investigated device are used simultaneously to record electrocardiograms. Conventional blood pressure taking are carried out in sequence with the investigated device. CARTs results from the conventional method are used as control.

DEVICE

Ambulatory holter station Model i12 plus

Model i12 plus (manufactured by RENCARE) is an ambulatory holter station, which was approved by the Center for Medical Device Evaluation (CMDE), China National Medical Products Association (NMPA). It can analyze electrocardiogram and generate HRV indices, which include SDNN, RMSSD, NN50, pNN50, triangular index, average RR, deceleration capacity (DC), deceleration runs (DRs), VLF, LF, HF, LF/HF, and total power. Model i12 plus is used to analyzed the same ECG signals as the investigated device.
