no. 1 Embodiment approach

[0064] Next, a first embodiment to which the present invention is applied will be described.

[0065] figure 2 It is a diagram showing an example of the system configuration of the left atrial pressure measurement device 800 in this embodiment. The left atrial pressure measurement device 800 of this embodiment is a computer system with the following parts, namely:

[0066] (1) Jugular venous pressure measuring device 810;

[0067] (2) Transthoracic echocardiography device 820;

[0068] (3) ECG device 830; and

[0069] (4) A processing device 840 that infers and calculates the left atrial pressure and stores it in time series.

[0070] The jugular venous pressure measuring device 810 of this embodiment is a known device that measures jugular venous pressure (JVP) through a jugular venous pressure measuring catheter 812 , and sequentially sends jugular venous pressure data to the processing device 840 .

[0071] The transthoracic echocardiography apparatus 820 is a heart u...

Abstract

The invention provides a new method for measuring left atrial pressure and a device for measuring left atrial pressure. The left atrial pressure measurement device includes a measurement unit that measures a first index value indicating the capacity of the right ventricle and a second index value indicating the capacity of the left ventricle; and a calculation unit that uses the first index value, the second index value and the The measured right atrial pressure is used to calculate the left atrial pressure.

Description

technical field [0001] The invention relates to a method for measuring left atrial pressure and the like. Background technique [0002] In evaluating cardiac function, in addition to blood pressure and cardiac output, left atrial pressure (left atrial pressure: LAP) is also important. Accordingly, various techniques for measuring left atrial pressure have been developed. For example, there is known a method that focuses on the passage of the esophagus through the front and back sides of the left atrium, inserts a catheter with a balloon at the tip into the esophagus, inflates it at a position adjacent to the left atrium, and measures the pressure in the balloon to measure the average left atrium pressure technology (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2006-142038 [0004] In the prior art described above, since it is necessary to indwell the balloon in the esophagus, a large burden has to be plac...
