Survey Of How Irregularities In The Electrical System Of The Human Heart Link To Different Heart Arrhythmias, Jazmine Boloor
Survey Of How Irregularities In The Electrical System Of The Human Heart Link To Different Heart Arrhythmias, Jazmine Boloor
UNLV Theses, Dissertations, Professional Papers, and Capstones
This thesis explores the circuital pathway that a signal takes within the heart throughout a full heartbeat and provides a timing analysis. It then surveys the different pathways that could arise in the electrical system of the heart, and the associated heart diseases linked to the location of each pathway. Common heart arrhythmias such as atrioventricular nodal reentrant tachycardia, atrioventricular reentrant tachycardia, atrial flutter, and atrial fibrillation are surveyed, and their pathways are analyzed. Electrocardiograms are presented to aid in understanding of the timing analysis associated with irregularity in heart function. Finally, this thesis explores an avenue of the heartbeat …

Oxygen Consumption In Highly Skilled Baseball Pitchers, Jesse Clingman
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to describe the physiological demands of highly skilled baseball pitchers during pitching, along with pitch metrics. Three junior college and three professional (n = 6) baseball pitchers participated in this study. Participants completed a graded exercise test (GXT) to volitional exhaustion to determine maximal oxygen consumption (VO2 max) and estimated body fat percentage, height, and body mass were measured on day one of testing. Next, participants faced live batters on a baseball field while wearing a portable metabolic analyzer (Cosmed K5) to measure respiratory gases including oxygen consumption (VO2) and carbon dioxide produced (VCO2) …
