Cardioversion Rate of Paroxysmal Supraventricular Tachycardia (PSVT) Treated by Blowing Syringe : A Pilot Study
Abstract
At present, there are several methods of valsalva maneuver for paroxysmal supraventricular tachycardia (PSVT) treatment, however there is no gold standard technique. Cardioversion rate is 5-20% in clinical practice. The new effective and evidence-based technique should be researched.
Objective: To study cardioversion rate of PSVT by blowing syringe technique.
Methods: A retrospective charts reviewing was conducted. The patients data (from March 2014 to August 2016) which were diagnosed as PSVT and treated by blowing 10 ml syringe in supine position for at least 15 seconds in strain duration were reviewed.
Results: Fifteen patients were enrolled. Six (40%) and nine (60%) were men and women respectively. Eight (53.3%) patients reverted to sinus rhythm by blowing syringe. No one had complication. Younger age related to higher cardioversion rate. [38.5±17.8 VS 47±6.2 years, (p-value 0.001)].
Conclusion: The pilot study indicates that valsalva maneuver by blowing syringe technique for paroxysmal supraventricular tachycardia treatment is effective; especially in younger age, convenient in clinical practice, non-invasive, economize and safe.
