Abstract

Atrial flutter with 1:1 atrioventricular conduction is a cardiac arrhythmia difficult to diagnose, fatal in many cases, and unmanageable with drug therapy. A number of 17 patients presenting with this disease was studied. A percentage of 70.6 % presented with throbbings, 64.7 % with syncope and important symptoms such as dizziness, sweating, and angina pectoris. The episode was solved with the use of antiarrythmic agents by endovenous route or electrical cardioversion. Ten patients had associated cardiovascular diseases such as arterial hypertension, ischemic heart disease, and aortic stenosis. During the follow-up 5 patients were controlled with the use of antiarrythmic drugs. Eleven patients underwent electrophysiologic studies with diagnostic or therapeutic purposes. When the drugs failed to be effective or the crisis of 1:1 atrial flutter was execrable for the patient, an electrical fulguration of the flutter focus (five cases) was performed. Two patients needed antiarrythmic agents even after the procedure and are now asymptomatic. Three cases with nonsuccessful ablation of the focus or associated atrial fibrillation underwent a fulguration of the atrioventricular node. All patients had a satisfactory evolution. This entity is poorly tolerated presenting a great deal of symptoms and the diagnosis and prevention with drugs is very difficult with no pharmacologic therapeutic possibilities.
