Incidental Cardiac Arrhythmia Identification With Consumer Grade Heart Rate Monitors: A Case Study, Neal C. Phifer
Incidental Cardiac Arrhythmia Identification With Consumer Grade Heart Rate Monitors: A Case Study, Neal C. Phifer
Theses and Dissertations
PURPOSE: The purpose of the study was to examine instances of using chest strap type heart rate monitor (HRM) data as a means of identifying otherwise asymptomatic individuals with possible cardiac arrhythmias as examined across four division one collegiate sports teams. METHODS: Heart rate activity was tracked across an entire season of four different division one collegiate teams (men’s basketball, women’s basketball, women’s soccer and women’s volleyball). A total of 65 athletes were equipped with heart rate monitors that were worn as allowed during practices and games. Data were collected using chest strap mounted activity sensors (Polar Team Pro sensors …

Deciphering The Consequences Of Yolk Testosterone Metabolism In Birds, Nicole A. Campbell

Maternal steroids transferred to eggs can elicit permanent effects on various aspects of offspring phenotype. Although, testosterone was thought to be a key mediator of maternal effects in birds, we now know that vertebrate embryos actively regulate their exposure to maternal testosterone through steroid metabolism, suggesting testosterone metabolites may elicit the observed phenotypic effects. To address the role steroid metabolism plays in mediating yolk testosterone effects, we used European starling (Sturnus vulgaris) eggs to characterize the timing of testosterone metabolism and determine whether etiocholanolone, a prominent testosterone metabolite in avian embryos, is capable of influencing early embryonic development. Tritiated testosterone …
