Simulation of Adenosine Push Methods for Treatment of SVT Using Agitated Saline Visualized by Ultrasound

Supraventricular tachycardia (SVT) is an abnormally fast heart rhythm arising from improper electrical activity in the upper part of the heart. SVT is commonly treated with adenosine using three different IV administration techniques. However, it is not well known which of these three techniques is the quickest or most likely to reach the heart in order to stop SVT. This study will simulate each of those techniques in an investigator-blinded procedure. Intravenous agitated saline, used as a surrogate for a dose of adenosine, will be administered to healthy volunteers using all three techniques and monitored using bedside ultrasound to observe their efficacy and speed in reaching the right side of the heart.
