Key result
Head-down deep breathing safely converts stable paroxysmal supraventricular tachycardia to sinus rhythm in two cases.
Why the study?
Does head down deep breathing convert paroxysmal supraventricular tachycardia to sinus rhythm in emergency department patients?
Case Report (n=2)
Does head down deep breathing convert paroxysmal supraventricular tachycardia to sinus rhythm in emergency department patients?
Head down deep breathing may serve as a simple, safe, and viable alternative vagal maneuver for treating stable PSVT in the emergency department.
May support testing head down deep breathing as a vagal maneuver in stable PSVT; leaves open efficacy and safety pending controlled trials.
The first-line recommended treatment for stable paroxysmal supraventricular tachycardia (PSVT) is the use of vagal maneuvers. Often the Valsalva maneuver is conducted. We describe two patients who converted to sinus rhythm without complications, using a head down deep breathing (HDDB) technique.

Lim et al. (2018) conducted a case report in Paroxysmal Supraventricular Tachycardia (n=2). Head down deep breathing (HDDB) was evaluated on Conversion to sinus rhythm. Head down deep breathing successfully converted two older female patients with stable paroxysmal supraventricular tachycardia to sinus rhythm without complications.
