A rapid approach to assess cardiac contractility by ballistocardiogram and electrocardiogram

A rapid approach to assess cardiac contractility by ballistocardiogram and electrocardiogram AbstractIn this paper, we propose a rapid assessment on cardiac contractility by using the time interval between the I wave of ballistocardiogram (BCG) and the R wave of electrocardiogram (ECG) which is referred to as the RI interval. The whole work can be divided into two parts. First, the correlation between the RI interval and the ejection fraction (EF), which is a clinical index to assess systolic performance, was computed. For 39 subjects, the correlation coefficient is −0.54 (p<0.001). Moreover, RI intervals of heart failure (HF) patients and healthy subjects were measured, and a significant difference was found among different New York Heart Association (NYHA) classes and the healthy group. Second, the beat-to-beat correlation analysis between the RI interval and the pre-ejection period (PEP), which is a parameter of systolic time interval to evaluate the cardiac contractility, was calculated. For 4578 heart beats across eight healthy subjects, the correlation coefficient is 0.85 (p<0.001). As a conclusion, these results indicate that the RI interval can be used as a noninvasive assessment of cardiac contractility. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Biomedical Engineering / Biomedizinische Technik de Gruyter

Abstract

AbstractIn this paper, we propose a rapid assessment on cardiac contractility by using the time interval between the I wave of ballistocardiogram (BCG) and the R wave of electrocardiogram (ECG) which is referred to as the RI interval. The whole work can be divided into two parts. First, the correlation between the RI interval and the ejection fraction (EF), which is a clinical index to assess systolic performance, was computed. For 39 subjects, the correlation coefficient is −0.54 (p<0.001). Moreover, RI intervals of heart failure (HF) patients and healthy subjects were measured, and a significant difference was found among different New York Heart Association (NYHA) classes and the healthy group. Second, the beat-to-beat correlation analysis between the RI interval and the pre-ejection period (PEP), which is a parameter of systolic time interval to evaluate the cardiac contractility, was calculated. For 4578 heart beats across eight healthy subjects, the correlation coefficient is 0.85 (p<0.001). As a conclusion, these results indicate that the RI interval can be used as a noninvasive assessment of cardiac contractility.
