Gabi Waite, PhD, is professor of physiology and immunology in the Department of Basic Sciences at Geisinger Commonwealth School of Medicine. Prior to joining Geisinger Commonwealth, Dr. Waite spent 15 years on the faculty at Indiana University School of Medicine (IUSM), where her career has encompassed most aspects of the delivery of medical education, including program and curricular development, basic science simulation teaching and competency assessment. She is a passionate educator and received four trustee teaching awards from IUSM and five teaching excellency awards. Prior to Geisinger Commonwealth, Dr. Waite studied the biophysical and redox regulation of inflammatory T lymphocytes by therapeutic electromagnetic fields. She spent a research sabbatical year at the University of Heidelberg, Germany. Her recent research focuses on the improvement of heart rate variability as a diagnostic and prognostic clinical tool. Dr. Waite is the editor or author of several books and book chapters, and over 60 other publications. Dr. Waite is also a research ambassador for the German Academic Exchange Service.
Heart rate variability (HRV) is a cardiology assessment derived from inexpensive electrocardiograms (ECG). It indicates the physiological state of the autonomic nervous system, which monitors and regulates the health of most body organs. In retrospective studies, it has been shown that convolutional neural networks can evaluate HRV to accurately diagnose a variety of human diseases and hence potentially lead to vastly improved and less costly healthcare. In prospective studies, HRV has been used for cardiovascular risk assessment and as health indicator for a variety of other diseases. However, HRV has not yet attained its clinical potential. Dr. Waite’s research employs a new big data platform to extract HRV from dis-structured archived ECGs and will apply deep learning based algorithms to determine a prognostic relationship between HRV and health. In the Human Performance Laboratory at Geisinger Commonwealth, studies are ongoing to determine clinically meaningful physiological HRV states and to better understand rhythmic HRV events. This knowledge is applied to clinical community studies, in order to develop HRV into a potent monitor of disease, of patient compliance to therapeutic instructions, and of lifestyle factors, all of which strongly influence HRV.
The 2017 implementation of the U.S. Medicare Access and CHIP Reauthorization Act (MACRA) expects clinical facilities to optimize therapeutic outcome, maximize economic efficiency and improve patient satisfaction. One path to all of these goals is to develop and deploy diagnostic tools that are accurate, have broad diagnostic applicability and are ideally noninvasive and economic. Dr. Waite is evaluating whether analysis of the very small differences in time between each heartbeat, known as heart rate variability (HRV), can be developed into such a clinical tool. This is likely since HRV is a monitor of the autonomic nervous system, which controls many critical organ functions. Thus, Dr. Waite’s research implements technologies to extract HRV data from stored electrocardiograms of normal and diseased individuals to determine whether there are specific changes in HRVs values that signal specific diseases. Similar, ongoing studies in the Scranton area measure HRV of normal and ill volunteers and patients. This work will ultimately help determine the role of HRV analysis in healthcare.
