摘要:
Disclosed is an arrhythmia diagnosing method and device for diagnosing arrhythmia such as fibrillation or tachycardia. The arrhythmia diagnosing method includes the steps of: (a) measuring a heart dimension; (b) measuring a frequency of a cardiac electric wave; (c) measuring a conduction velocity of the cardiac electric wave; and (d) determining occurrence or absence of arrhythmia using the heart dimension, the frequency of the cardiac electric wave and the conduction velocity of the cardiac electric wave measured in steps (a), (b) and (c). With the present invention, it is possible to predict and diagnose an electric wave tornado, one of causes of arrhythmia, through the use of a non-dimensional parameter, to find out patents who may possibly be died of arrhythmia or may possibly come to brain death due to arrhythmia and to significantly reduce the mortality rate of patients who suffer from arrhythmia.
摘要:
The present invention relates to a method for determining patient-specific blood vessel information. More specifically, the present invention relates to a method for determining patient-specific cardiovascular information by applying a simplified coronary circulation model thereto. Furthermore, the present invention relates to a method for determining a blood flow rate for branches of a blood vessel having originated from an artery of each patient. According to the present invention, the method for determining cardiovascular information by using a computer system comprises the steps of: receiving image data including a plurality of coronary arteries having originated from the aorta; processing the image data so as to generate a three-dimensional shape model of the plurality of coronary arteries; simulating a blood flow for the generated three-dimensional shape model of the plurality of coronary arteries; and determining a fractional flow reserve (FFR) of the respective coronary arteries with the blood flow simulation result. In the blood flow simulation step for the three-dimensional shape model of the plurality of coronary arteries, a computational fluid dynamics model is applied to the three-dimensional shape model of the coronary arteries, and a centralized parameter model to be combined with the computational fluid dynamics model uses a simplified coronary circulation model including coronary arteries, capillaries of the coronary arteries, and coronary veins.
