Familial sick sinus syndrome with atrioventricular conduction disturbance.
A family with sick sinus syndrome is presented: a mother and her 2 daughters affected with sinus node dysfunction. Electrophysiological studies revealed abnormal atrioventricular conduction in the 2 daughters. All 3 individuals were implanted with a permanent pacemaker to relieve their symptoms. Endomyocardial biopsy from the right ventricle of one daughter showed disarrangement, degeneration, ...
متن کاملRole of autonomic regulatory mechanism in sinoatrial conduction and sinus node automaticity in sick sinus syndrome.
To assess the role of autonomic regulatory mechanisms on sinoatrial conduction and automaticity in patients with clinical evidence of sick sinus syndrome, electrophysiologic studies were conducted in 12 male patients, mean age 64 4 7 years. Heart rate, sinus node recovery time (SNRT) and sinoatrial conduction time (SACT) were determined before and after autonomic blockade with atropine (0.04 mg...

متن کاملSick sinus syndrome in children.
The ages of 6 male patients with the sick sinus syndrome ranged from 10-15 years when their symptoms began. At rest all had a heart rate of 60/min or less. Two had syncopal attacks which threatened life; 1 had only attacks of dizziness; the other 3 had no syncopal attacks but had recurrent attacks of supraventricular tachycardia ('brady-tachycardia syndrome') which were more resistant to drug t...
