Cardiac conduction in patients with symptomatic sinus node disease.
Cardiac conduction was investigated at the time of pacemaker insertion in 15 patients with symptomatic sinus node disease. Techniques included recording of His bundle potentials, atrial pacing at various heart rates, and atropine administration. Atrioventricular (AV) conduction was impaired in eight patients who manifested one or more of the following: P-R prolongation, P-H prolongation, and de...
متن کاملAssociation of sinus node dysfunction, atrioventricular node conduction abnormality and ventricular arrhythmia in patients with Kawasaki disease and coronary involvement.
BACKGROUND This study was performed to investigate the incidence of arrhythmias in patients with Kawasaki disease (KD). METHODS AND RESULTS Electrophysiologic studies (EPS) were performed in 40 patients (mean age: 10.3+/-5.1 years; 30 males, 10 females) with KD who had severe to moderate coronary artery disease. Clinical arrhythmias were documented in 4 patients (premature ventricular contrac...
متن کاملSymptomatic sinus node disease: natural history after permanent ventricular pacing.
Fifty-nine patients between the ages of 13 and 88 with sinus node disease, who received a permanent ventricular pacemaker between 1965 and 1976 at one institution, were followed to determine the natural history of the disorder after permanent pacing. Nineteen had ischemic heart disease, six had primary myocardial disease, and eight valvular heart disease. In 26, no etiology for the arrhythmia w...
متن کاملSinus node recovery time and calculated sinoatrial conduction time in normal subjects and patients with sinus node dysfunction.
In 61 patients sinus node function was tested by programmed (sinoatrial conduction time, SACT) and overdrive atrial pacing (sinus node recovery time, SRT). In the control group (N = 20), mean sinus cycle length was 773 +/- 140.2 msec, mean absolute SRT 1044 +/- 215.8 msec [corrected SRT (CSRT) 270 +/- 112.5 msec; mean +/- SD] and calculated SACT was 82 +/-19.2 msec. The upper limit of normal SA...
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...
