Depression is a strong risk factor for chronic illness. It also increases the risk of morbidity and mortality associated with cardiovascular disease (CVD). Heart Rate Variability (HRV) analysis, which characterizes cardiovascular health and depression status can provide information on any pathophysiological effect of depression on CVD and also effect of CVD on depression. HRV measures provide additional information to the physician to improve the management of depression and prevent CVD-associated mortality. In this study time and frequency domain HRV measures were investigated for 67 cases with different levels of depression classified according to the Patient Health Questionnaire (PHQ-9). A new four-level depression range of PHQ-9 scores was then obtained by systematically modifying the standard ranges, to achieve the highest statistical HRV difference between the categories. In order to assist the assessment of depression, its progression and associated cardiovascular condition, an illustrative circular mapping of HRV measures was developed. This HRV infographic shows the normal range of HRV measures, and provides a simple graphical illustration for identifying abnormal HRV and stage of depression based on the modified PHQ-9 scale.

|Other||The overall theme of the conference is “Personalized Healthcare & Wearables”. The IEEE Life Sciences Technical Community (LSTC), which is supported by multiple IEEE member societies, is the sponsor of the conference. As such, the conference will cover diverse topics within the theme.|
LSC 2017 will include tutorials and a scientific program composed of plenary talks, invited sessions, and poster presentations of peer-reviewed papers. In addition, there will be a host of special events, including a Standards Track, an IEEE Women in Engineering event, a High School Competition, an e-textile style fashion show, and an IBM Big Data/Watson event in partnership with the IEEE Big Data Initiative. All are encouraged to submit papers containing original contributions to be considered for presentation at LSC 2017. Accepted 4-page regular papers will be published in the conference proceedings and included in IEEE Xplore. To communicate late scientific findings and to encourage attendance by a broader audience, LSC 2017 will provide additional presentation opportunities via a second track featuring posters.
