Cardiovascular function detection method based on multi-channel pulse wave form analysis and device thereof

Abstract

The invention discloses a cardiovascular function detection method based on multi-channel pulse wave form analysis and a device thereof. A cardiovascular function evaluation index system suitable for health screening and personal dynamic detection is built by collecting blood pressure of upper limbs and lower limbs and multi-channel pulse wave form of neck, thigh, radio and ankle, and quality analysis and control can be conducted on evaluation index in the system. Simultaneously, the device is convenient to operate, low in cost and capable of well meeting requirements of large crowd for cardiovascular disease screening.

Description

technical field [0001] The invention relates to early screening and prevention of cardiovascular diseases in biomedicine, in particular to a cardiovascular function detection method and device thereof based on multi-channel pulse wave waveform analysis. Background technique [0002] Cardiovascular disease is the most important disease threatening human health today. At present, my country estimates that 3.5 million people die from cardiovascular disease every year, and 2 out of 5 deaths are caused by cardiovascular disease. In recent years, the mortality rate of cardiovascular disease is still relatively high. In 2010, the mortality rate of cardiovascular disease still ranked first, higher than that of tumors and other diseases ("China Cardiovascular Disease Report 2011"). Due to the high morbidity and mortality of cardiovascular disease, cardiovascular disease has become one of the most important public health problems in my country and even in the world. [0003] As an i...

Problems solved by technology

For example, when the PWV is accelerated, the reflected wave will reach the heart earlier, which will bring negative effects on the cardiovascular system in the following three aspects: First, aortic systolic blood pressure (SBPa) and aortic pulse pressure (aortic puls pressure (PPa) increases, increasing cardiovascular and cerebrovascular load and stroke risk

Second, the left ventricular afterload increases, accelerates the increase of left ventricular volume, and increases the incidence of myocardial hypertrophy

Third, coronary perfusion pressure decreases, increasing the risk of myocardial ischemia

At the same time, due to its high price and complicated operation, the measurement operation needs to be completed under the guidance of professionals, so it is difficult to be used for group screening and general surveys
