This episode is part of ACC's ongoing educational initiative to enhance the recognition, diagnosis, and management of paroxysmal supraventricular tachycardia (PSVT). Faculty review contemporary acute treatment approaches, including established therapies, recent advances, and first-line emergency department strategies with attention to efficacy and safety. The discussion also addresses management of refractory or recurrent cases, decision-making across diverse patient populations and care settings, and criteria for hospital admission versus discharge. Additionally, it provides practical guidance on patient education, symptom recognition, and selecting treatments that balance effectiveness, safety, convenience, and patient confidence.
