Final answer:
SVT is an arrhythmia treated with medications like verapamil and adenosine, and in severe cases, with electric shock cardioversion or defibrillation. In surgeries or chronic cases, an artificial pacemaker or defibrillator may be used for heart rhythm management.
Step-by-step explanation:
Supraventricular tachycardia (SVT) is a type of arrhythmia originating above the ventricles that lead to an abnormally fast heartbeat. Treatments for this condition include pharmacological interventions such as verapamil, a medication taken orally to help control the heart rate, and adenosine, an intravenous medication that can normalize heart rhythm. For severe cases, when medications do not suffice, treatments like electric shock cardioversion or defibrillation may be used to restore a normal sinus rhythm. In a hospital scenario, cardiovascular support might also involve the use of an artificial pacemaker or external automated defibrillators (EADs). During surgeries, protocols including the use of KCl to stop the heart and precise calculations of voltage for a defibrillator are enacted to manage arrhythmic events and maintain heart function.
