Clinical Question :When managing Paroxysmal Supraventricular Tachycardia (PSVT), we routinely utilize a 3-way stopcock to perform the two-syringe technique for Adenosine administration, as demonstrated in the video..Why must Adenosine be administered using the rapid two-syringe technique (drug + 20 mL saline flush)? And what physical maneuver should be performed on the patient's arm immediately after injection to enhance efficacy?🤔🤔
