Immediate Effects of Intravenous Verapamil in Cardiac Arrhythmias

摘要: Verapamil was administered by intravenous injection to 181 patients with various cardiac arrhythmias. The automaticity of the pacemaker slowed in sinus, idionodal, and idioventricular tachycardia. In atrial fibrillation drug usually ventricular response often made it regular. some cases flutter converted sinus rhythm, being reduced remainder. Conversion paroxysmal supraventricular tachycardia rhythm consistently achieved. A favourable occurred four whom arrhythmias were associated pre-excitation syndromes. There no adverse clinical side effects.
