As a domain expert in emergency medicine, I can provide you with an informed response to your question about SVT, which stands for Supraventricular Tachycardia. SVT is a rapid heart rate that originates above the ventricles, typically in the atria or the atrioventricular (AV) node. It is not typically considered a shockable rhythm because it is not immediately life-threatening like ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). The treatment for SVT usually involves attempts to slow the heart rate through various maneuvers such as vagal maneuvers or the administration of medications like adenosine. In some cases, electrical cardioversion may be used, but this is not the same as defibrillation for shockable rhythms. Here's the response with the separation as requested: **SVT is generally not considered a shockable rhythm.** Treatment for SVT typically involves attempts to slow the heart rate through vagal maneuvers or the administration of medications like adenosine. Electrical cardioversion may be used in some cases, but it is not the same as defibrillation for shockable rhythms. read more >>

Patients in a supraventricular tachycardia will have a rapid rhythm with a heart rate greater than 150 beats per minute. ... The shock that is delivered in cardioversion for SVT is synchronized to occur at a precise time, one that avoids the vulnerable refractory period which could cause ventricular fibrillation.read more >>
