Clinical electrophysiological effects of propranolol on normal sinus node function.
In 35 patients aged 18 to 69 years (mean 48) with clinical, electrocardiographic, or electrophysiological evidence of normal sinus node function, the effect of intravenous propranolol (0.1 mg/kg) was assessed on 3 indices of sinus node function. The drug significantly prolonged sinus node cycle length (12%), slightly prolonged the corrected sinus node recovery time (15%), and slightly but insig...
متن کاملRemodeling of sinus node function in patients with congestive heart failure: reduction in sinus node reserve.
BACKGROUND Experimental and clinical studies have demonstrated diffuse atrial remodeling in congestive heart failure (CHF). We hypothesized that patients with CHF would demonstrate derangement of sinus node function. METHODS AND RESULTS Eighteen patients with symptomatic CHF (left ventricular ejection fraction, 26+/-5%) and 18 age-matched control subjects were studied. Under autonomic blockad...
متن کاملElectrophysiologic effects of disopyramide phosphate on sinus node function in patients with sinus node dysfunction.
The electrophysiologic effects of intravenously administered disopyramide (2 mg/kg) on three parameters of sinus node function were examined in 16 symptomatic patients with sinus node dysfunction. Based on their ECG data before study, patients were subdivided into group A (n = 8), those with sinus pauses and/or sinoatrial (SA) exit block; and group B (n = 8), those with sinus bradycardia. Disop...
متن کاملElectrophysiologic evaluation of sinus node function in patients with sinus node dysfunction.
Twenty patients of mean age 66.2 years, with suspected sinus node dysfunction, underwent extensive electrophysiologic study. Sinus bradycardia (18), sinus pauses (3), and sinoatrial block (1) were identified in their ECGs prior to study. Also 11 patients had some abnormality of atrioventricular nodal and/or intraventricular conduction prior to study. At the time of electrophysiological study, 1...
متن کاملElectrophysiologic effects of propranolol on sinus node function in patients with sinus node dysfunction.
The electrophysiologic effects of intravenously administered propranolol (0.1 mg/kg) on three parameters of sinus node function were examined in ten symptomatic patients with sinus node dysfunction. The patients ranged in age from 26 to 79 years. Symptoms ranged from fatigue to frank syncope. Sinoatrial (SA) block and sinus pauses were observed in one patient; sinus pauses alone were observed i...
