The system of the invention is actually a Holter system which records 24-hour recording electrocardio, blood pressure and blood oxygen saturation data, performs synchronous analysis and combines reports of multiple parameters. The system comprises a recorder and a computer provided with 3-parameter data analysis software. The recorder records and stores 24-hour dynamic electrocardio, blood pressure and blood oxygen saturation data. After the data are transmitted into a computer (computer), the data are analyzed by 3-parameter data analysis software, and the analysis result is reported. Fig. 5 is a schematic diagram of an application scenario provided by the present invention, as shown in fig. 5.
Within the patient environment: the patient wears a recorder with a cardiac electric lead, a blood pressure cuff and a blood oxygen probe, the recorder sets a blood pressure measurement time interval after being started, synchronously acquires the electrocardio and blood oxygen data, starts blood pressure measurement (completes inflation, deflation, works such as calculating blood pressure data by an oscillometric method and the like) according to the set blood pressure measurement interval, stores the data in the recorder and records the data for 24 hours.
Outside the patient environment: after the recording is completed for 24 hours, the recorder is detached from the patient, the data in the recorder is transmitted to a computer (namely, the data analysis equipment in fig. 2 and 4) through a data line, then synchronous analysis (or called fusion analysis) is carried out by using 3-parameter data analysis software of the computer to form a 3-parameter synchronous analysis report (or called fusion analysis report), and the 3-parameter data and the analysis report can be printed by a laser printer.
The electrocardio data are collected by the electrocardio lead wire, and the sampling frequency of the electrocardio data is 125Hz-500Hz; the blood oxygen probe acquires blood oxygen data, and the sampling frequency of the blood oxygen saturation is usually 1Hz-2Hz; blood pressure cuff measures blood pressure data, blood pressure being measured by oscillometric method, with sampling intervals typically being 5 minutes to 2 hours.
In order to synchronously observe and analyze data of electrocardio, blood pressure and blood oxygen, the values of the electrocardio, the blood pressure and the blood oxygen saturation at any moment (accurate to seconds) are ensured to be observed. The electrocardio data and the blood oxygen data are continuously measured, but the blood pressure data are intermittently measured, the measurement interval is usually between 5 minutes and 2 hours, and no blood pressure value exists at other time except the measurement time, so the invention obtains dynamic blood pressure continuous data by using the intermittently measured blood pressure data, considers that the change of the human blood pressure is a gradual change process, assumes a linear relation of the blood pressure values between two adjacent measurement points, and based on the linear relation, the blood pressure value (systolic pressure S, diastolic pressure D) at any time is calculated by the actually measured pressure of the two adjacent measurement points. For example, the blood pressure values at the time t1 are measured as (systolic pressure S1, diastolic pressure D1), the blood pressure values at the time t2 adjacent to the measurement point are measured as (systolic pressure S2, diastolic pressure D2), and the blood pressure value at any time t between the time t1 and the time t2 is as follows:
systolic blood pressure S = (S2-S1) × (t-t 1)/(t 2-t 1) + S1;
diastolic pressure D = (D2-D1) × (t-t 1)/(t 2-t 1) + D1;
based on the above principle, the blood pressure value at any time between adjacent measurement points in the test period (for example, 24 hours) can be calculated, and finally, the blood pressure value at any time in the test period (for example, 24 hours), that is, the dynamic blood pressure data can be obtained. Thus, the data of the electrocardio, the blood pressure and the blood oxygen saturation at any moment can be provided for clinical use.
The above-mentioned 3 parameter data can be analyzed and counted by using 3 parameter analysis software, and a fusion analysis report of dynamic 24-hour ECG blood pressure and blood oxygen is formed, for example, the pole and mean values of the occurrence of each parameter and the occurrence time thereof, the frequency of occurrence of various abnormal events, the time and time sequence relationship are analyzed, so as to provide various statistical data required for clinical judgment and analysis of the etiology of the patient.
In conclusion, the continuous blood pressure data in the whole time period of 24 hours is obtained based on the blood pressure data measured intermittently, the electrocardio, blood pressure and blood oxygen data at any time can be observed in the data analysis result, and complete data are provided for the synchronous analysis of the 3 parameters.
