Question: If the Valsalva Maneuver is not a medically controlled act why would a PCP not be able to carry out this procedure for a symptomatic narrow complex, regular rhythm tachycardia that is symptomatic? PCP's are supposed to be able to identify sinus tachycardia, atrial fibrillation or atrial flutter which would be contraindicated and especially if no other immediate care is available. Why such be restricted to only ACP's, again especially if no other immediate care is available?
Good question. It seems to be a reasonable thing to try for a normotensive patient with symptomatic regular narrow complex tachycardia. It is important to be able to be able to recognize SVT in order to utilize this manoeuver.
Here is an excellent resource that outlines ECG features of SVT: https://lifeinthefastlane.com/ecg-library/svt/
Remember to document this procedure on your ACR.
