INDUCED HYPOTHERMIA AND ITS EFFECTS ON CARDIAC ARRHYTHMIAS.
Creator

Abstract / Description
The purpose of this integrated review of the literature was to determine the relationship between therapeutic hypothermia and cardiac arrhythmias. The reviewed literatures were English based articles from year 2003-2013. Relevant information from the American Heart Association and the International Liaison Committee on Resuscitation was used to further enhance research results. The results of this literature review showed hypothermia treatment propensity to prolong QT interval without...
Show moreThe purpose of this integrated review of the literature was to determine the relationship between therapeutic hypothermia and cardiac arrhythmias. The reviewed literatures were English based articles from year 2003-2013. Relevant information from the American Heart Association and the International Liaison Committee on Resuscitation was used to further enhance research results. The results of this literature review showed hypothermia treatment propensity to prolong QT interval without precipitating life-threatening arrhythmias. Although arrhythmias can be potentially increased under induced hypothermia, it has been shown that treatment is easier while under hypothermic conditions. The reviewed research also shows that hypothermia treatment should be expanded to include more circumstance besides ventricular cardiac arrest. It was suggested that the reason for lack of use of hypothermia treatment under the suggested conditions was due to the restricted circumstances in which it is suggested to be used. Other recommendations include increased monitoring for cardiac rhythms during cardiac arrhythmias and protocols for arrhythmia treatment.

AN AUTHENTIC ECG SIMULATOR
Title
AN AUTHENTIC ECG SIMULATOR.
Creator
Michalek, Paul, Weeks, Arthur, University of Central Florida
Abstract / Description
An ECG (electrocardiogram) simulator is an electronic tool that plays an essential role in the testing, design, and development of ECG monitors and other ECG equipment. Principally an ECG simulator provides ECG monitors with an electrical signal that emulates the human heart's electrical signal so that the monitor can be tested for reliability and important diagnostic capabilities. However, the current portable commercially available ECG simulators are lacking in their ability to fully...
Show moreAn ECG (electrocardiogram) simulator is an electronic tool that plays an essential role in the testing, design, and development of ECG monitors and other ECG equipment. Principally an ECG simulator provides ECG monitors with an electrical signal that emulates the human heart's electrical signal so that the monitor can be tested for reliability and important diagnostic capabilities. However, the current portable commercially available ECG simulators are lacking in their ability to fully test ECG monitors. Specifically, the portable simulators presently on the market do not produce authentic ECG signals but rather they endeavor to create the ECG signals mathematically. They even attempt to mathematically create arrhythmias (irregular heartbeats of which there are many different types). Arrhythmia detection is an important capability for any modern ECG monitor because arrhythmias are often the critical link to the diagnosis of heart conditions or cardiovascular disease. The focus of this thesis is the design and implementation of a portable ECG simulator. The important innovation of this prototype simulator is that it will not create its ECG signals mathematically, but rather it will store ECG data files on a memory module and use this data to produce an authentic ECG signal. The data files will consist of different types of ECG signals including different types of arrhythmias. The data files are obtained via the internet and require formatting and storing onto a memory chip. These files are then processed by a digital to analog converter and output on a four lead network to produce an authentic ECG signal. The system is built around the ultra-low power Texas Instruments MSP430 microcontroller.

Is Selective Mutism an Emotion Regulation Strategy for Children with Social Phobia? A Single Case Design Investigation
Title
Is Selective Mutism an Emotion Regulation Strategy for Children with Social Phobia? A Single Case Design Investigation.
Creator

Abstract / Description
To determine whether children with selective mutism (SM) withhold speech to regulate their emotional arousal and decrease automatic distress, the current study examines the behavioral and physiological responses of children with SM in comparison to children with social phobia (SP) and children with no psychiatric disorder (TD) as they participate in two social situations. A single case design strategy is used to compare behavioral and physiological responses both within and across groups....
Show moreTo determine whether children with selective mutism (SM) withhold speech to regulate their emotional arousal and decrease automatic distress, the current study examines the behavioral and physiological responses of children with SM in comparison to children with social phobia (SP) and children with no psychiatric disorder (TD) as they participate in two social situations. A single case design strategy is used to compare behavioral and physiological responses both within and across groups. Examining the temporal sequencing of behaviors and physiology provides a direct test of the utility of emotion regulation theory as it pertains to children with social phobia/selective mutism. The results indicate that children with SM show elevated arousal and emotional reactivity across all interaction segments relative to other children. Unique affective, behavioral and physiological responses occur between and within groups in relation to situational demands. The temporal sequencing of behavioral and physiological responses suggests that behavioral deficits may be related to underutilized and/or deficient physiological response systems and that not speaking represents a primitive avoidance strategy by children with SM to regulate extreme physiological arousal.

Does Virtual Reality Elicit Physiological Arousal in Social Anxiety Disorder
Title
Does Virtual Reality Elicit Physiological Arousal in Social Anxiety Disorder.
Creator
Owens, Maryann, Beidel, Deborah, Cassisi, Jeffrey, Bowers, Clint, Neer, Sandra, University of Central Florida
Abstract / Description
The present study examined the ability of a Virtual Reality (VR) public speaking task to elicit physiological arousal in adults with SAD (n=25) and Controls (n=25). A behavioral assessment paradigm was employed to address three study objectives: (a) to determine whether the VR task can elicit significant increases in physiological response over baseline resting conditions (b) to determine if individuals with SAD have a greater increase from baseline levels of physiological and self-reported...
Show moreThe present study examined the ability of a Virtual Reality (VR) public speaking task to elicit physiological arousal in adults with SAD (n=25) and Controls (n=25). A behavioral assessment paradigm was employed to address three study objectives: (a) to determine whether the VR task can elicit significant increases in physiological response over baseline resting conditions (b) to determine if individuals with SAD have a greater increase from baseline levels of physiological and self-reported arousal during the in vivo speech task as opposed to the VR speech task and (c) to determine whether individuals with SAD experience greater changes in physiological and self-reported arousal during each speech task compared to controls. Results demonstrated that the VR task was able to elicit significant increases in heart rate, skin conductance, and respiratory sinus arrhythmia, but did not elicit as much physiological or self-reported arousal as the in vivo speech task. In addition, no differences were found between groups. Clinical implications of these findings are discussed.
