Reliabliity assessment of cardiac parameter measurements

Abstract

A method () for assessing reliability of a cardiac parameter of a subject is disclosed. The method comprises receiving data () from a transesophageal echocardiography probe, a heart activity sensor, and a motion sensor, determining () a TEE cardiac parameter relating to the cardiac parameter estimated using data from the transesophageal echocardiography probe, determining a heart activity cardiac parameter relating to the cardiac parameter estimated using data from the heart activity sensor, determining () the cardiac parameter based on at least one of the TEE and heart activity parameters, assessing the reliability of the cardiac parameter based on the TEE and heart activity parameters and the data from the motion sensor, and transmitting to an output device, a feedback signal based on the reliability of the cardiac parameter. In accordance with the invention, the method further comprises determining () a cardiac parameter trend and whether the cardiac parameter trend exceeds a trend threshold, detecting motion of the subject () during a first time period, based on the data of the motion sensor, and assessing the reliability of the cardiac parameter based on whether the cardiac parameter trend exceeds the trend threshold and on whether motion of the subject has been detected. Also disclosed are a computer program and a system () for implementing such a method.
