Effectiveness of Repeating Valsalva Maneuver in Paroxysmal Supraventricular Tachycardia patients Nonresponsive to Initial Valsalva Maneuver and a Single Dose of Verapamil.
J Sharif Med Dent Coll Jan ;5(2):80-4.

Objective: To determine the effectiveness of repeating Valsalva maneuver in paroxysmal supraventricular tachycardia (PSVT) patients nonresponsive to initial valsalva maneuver and a single dose of verapamil. Methodology: It was a descriptive case series conducted in the Emergency Department of the Punjab Institute of Cardiology, Lahore. The study was approved by the ethical committee of the institution. A total of 100 patients were enrolled by nonprobability consecutive sampling technique by taking informed written consent. The patients of any age or gender presenting with an acute episode of PSVT confirmed on ECG and nonresponsive to initial valsalva maneuver & a single dose of verapamil were included. Patients were given a trial of the valsalva maneuver. The heart rate and rhythm of the patients were continuously observed with a cardiac monitor. Repeat ECG was done 1 minute after performing the Valsalva maneuver. The data was analyzed using the Statistical Package for the Social Sciences (SPSS) version 24. Results: The mean age of the patients was 56.48?15.57 years. Seventy four (74%) patients were males and 26(26%) patients were females. Out of 100 patients nonresponsive to initial valsalva maneuver and a single verapamil dose, reversion of supraventricular tachycardia was noted in 27(27%) patients. There was a statistically significant association between gender, BMI, smoking and SVT reversion. Conclusion: The reversion rate of paroxysmal SVT with repeat valsalva maneuver after the failure of an initial trial of valvalsa maneuver and a single dose of verapamil is satisfactory. The reversion of supraventricular tachycardia was noted in 27% of cases in our study. Keywords: Valsvalva maneuver. Paroxysmal supraventricular tachycardia. Verapamil.
