“Forced inspiratory suction and swallow tool” a novel instrument to convert paroxysmal supraventricular tachycardia (SVT) to sinus rhythm, a case report and introduction of the device

Paroxysmal Supraventricular Tachycardia (SVT) is an arrhythmia with sudden onset and termination, characterized by a fast heart rate and a narrow QRS complex. There are several remedies that have been described to convert the SVT, such as the Valsalva maneuver, holding the breath for a few seconds, or putting cold water on the face. Here we are presenting a case of SVT, which we converted to sinus rhythm instantly by using a novel tool that has been designed and patented at the University of Texas. This device is named “Forced Inspiratory Suction and Swallow Tool” (FISST) and is branded as “HiccAway,” which is primarily designed to stop hiccups and is available as an over-the-counter tool. It works by drinking water forcibly through a pressure valve, and it follows “Bernoulli's Principle”: applications of the law of conservation energy.
