Abstract
The present invention relates to a cardiovascular diagnostic system which enables early detection of cardiovascular diseases and defines their causes. Unlike known electrocardiographs, the cardiovascular diagnosis system can further measure elastic coefficient of blood vessels (the degree of arteriosclerosis), blood vessel compliance, blood flow, and blood flow resistance and velocity in blood vessel branches of the right and left coronary arteries. The elastic coefficient shows organic changes to blood vessels. The compliance shows organic and functional changes of blood vessels simultaneously. The blood flow shows blood flow resistance.
Claims72
A cardiovascular analyzer comprising:
- a bio-signal measurement system including a bio-signal measuring sensor unit which comprises an electrocardiogram (ECG) sensor, a phonocardiogram (PCG) sensor and one or more accelerated plethysmogram (APG) sensors, and a bio-signal reception and process unit which is connected to each of the sensors of the bio-signal measuring sensor unit for receiving and processing bio-signals measured by the sensors;
- and
- an analysis indicator calculation system including a main processing unit which is connected to the bio-signal reception and process unit for communicating and calculating biodynamic indicators of a coronary artery from the bio-signals, an input unit which is connected to the main processing unit for receiving control commends of user, and an output unit which is connected to the main processing unit for displaying the calculated results,
- wherein the main processing unit is configured to synthesizes an aortic arch internal pressure curve P from the bio-signals measured by the bio-signal measurement system and to calculates the biodynamic indicators from an area of the aortic arch internal pressure curve P.
