the frequency of reversion of paroxysmal supra-ventricular tachycardia with valsalva maneuver.
Pak J Surg Jan ;34(3):219-23.

Background: Paroxysmal supra-ventricular tachycardia (PSVT) is a type of supra-ventricular tachycardia. PSVT is an episodic condition with an abrupt onset and termination. Studies show that Valsalva maneuver is the most potent physical maneuver to revert PSVT. Reversion rate of valsalva maneuver is satisfactory, but controversial evidences have been noticed in literature. This study was conducted to assess the frequency of reversion of paroxysmal supraventricular tachycardia with valsalva maneuver. Study design: Descriptive case series Setting: Emergency department, Punjab Institute of Cardiology Duration: 4th August 2016 to 3rd February 2017 Material and Methods: One hundred patients admitt ed with supra-ventricular tachycardia were recruited and were given a trial of valsalva maneuver for a minimum duration of 15 seconds. Repeat ECG was done 1 minute after performing valsalva maneuver. If normal sinus rhythm was observed <100 beats/min assessed on ECG, then reversion of tachycardia was labeled. All the collected data was entered and analyzed on SPSS version 21. Results: Total number of patients were 100,74 % were male and 26% were female. The mean age of patients was 56.48±15.57 years. The success rate of valsalva maneuver in reversion was noted in 23(23%) patients. Statistically significant difference was observed between reversion of SVT and gender. Conclusion: the success rate of valsalva maneuver in reversion of paroxysmal SVT was satisfactory and this method can be performed in emergency to revert SVT as it is easy and cost effective.
