Electrophysiologic effects of adenosine in patients with supraventricular tachycardia.
BACKGROUND We correlated the electrophysiologic (EP) effects of adenosine with tachycardia mechanisms in patients with supraventricular tachycardias (SVT). METHODS AND RESULTS Adenosine was administered to 229 patients with SVTs during EP study: atrioventricular (AV) reentry (AVRT; n=59), typical atrioventricular node reentry (AVNRT; n=82), atypical AVNRT (n=13), permanent junctional reciproc...
متن کاملAn electrophysiologic study of swallowing-induced tachycardia.
Electrophysiologic studies were performed on a 73-year-old man with swallowing-induced supraventricular tachycardia, in order to define the characteristics of this unique dysrhythmia in this patient. Swallowing reliably provoked an automatic atrial focus type of atrial tachycardia, which usually changed into an atrioventricular nodal reentrant tachycardia when a critical delay in atrioventricul...
متن کاملEfficacy and safety of intravenous and oral nadolol for supraventricular tachycardia in children.
The efficacy and safety of oral nadolol in supraventricular tachycardia were evaluated prospectively in 27 children (median age 5.5 years). Fifteen patients had an unsuccessful trial of digoxin therapy. Intravenous nadolol was given to seven patients during electrophysiologic study; five of these had an excellent response and two had a partial response (25% decrease in tachycardia rate). Six of...
متن کاملSyncope and supraventricular tachycardia.
A41-year-old man was referred for electrophysiological evaluation after recurrent syncope that occurred frequently during vigorous exercise. The patient had a complete, normal cardiological work up, including a resting ECG, an exercise stress test, and an echocardiogram. He reported that just before loss of consciousness, his heart was beating very fast. An electrophysiological study was perfor...
متن کاملDermatomyositis and supraventricular tachycardia
BACKGROUND Dermatomyositis is an idiopathic inflammatory myopathy, often associated with an underlying malignancy. Its prevalence rate is approximately one per 100,000 in the general population, and is even rarer without evidence of a cancer. Dermatomyositis rarely involves myocardial muscle fibers, but has shown to be associated with cardiac arrhythmias. CASE PRESENTATION We present a case o...
