Clinical study of sublingual verapamil n paroxysmal supraventricular tachycardia

Objective To research the effect of sublingual verapamil on Paroxysmal supraventricular tachycardia (PSVT). Methods 42 patients with PSVT by electrocardiograghic diagnosis were randomly divided into 2 groups ,22 patients by Sublingual verapamil (A group) and 20 patients by intravenous verapamil(B group),and compared. Making notes of BP、HR、 symptoms before drug was used and after PSVT was converted,and acting(when HR descended beyond 20 bpm) and converted tme of PSVT. Results A group:acting time (7. 05±1. 79)min,converted time 1(1. 14±8. 82)min and succeeding rate 90. 90%. B group:acting time (7. 27±3. 13)min,converted time (9. 15±6. 81)min and succeeding rate 95. 00%. The effect of sublingual Verapamil is as good as compared with intravenons verapamil (P0. 05). Conclusion This is an easy rapid acting and effective way to treat the patients with PSVT,it has no obvious side effect. Therefore it has a promising future in clinical Practice.
