Ventricular pacing or dual-chamber pacing for sinus-node dysfunction.
BACKGROUND Dual-chamber (atrioventricular) and single-chamber (ventricular) pacing are alternative treatment approaches for sinus-node dysfunction that causes clinically significant bradycardia. However, it is unknown which type of pacing results in the better outcome. METHODS We randomly assigned a total of 2010 patients with sinus-node dysfunction to dual-chamber pacing (1014 patients) or v...
متن کاملCost-effectiveness of dual-chamber pacing compared with ventricular pacing for sinus node dysfunction.
BACKGROUND Compared with single-chamber ventricular pacing, dual-chamber pacing can reduce adverse events and, as a result, improve quality of life in patients paced for sick sinus syndrome. It is not clear, however, how these benefits compare with the increased cost of dual-chamber pacemakers. METHODS AND RESULTS We used 4-year data from a 2010-patient, randomized trial to estimate the incre...
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 Dysfunction
Sinus node dysfunction is de~ned as inappropriate sinus bradycardia or abnormal pauses in sinus mechanism. Sinus node dysfunction often coexists with atrial ~brillation, _utter, or tachycardia, and in such cases may be termed “tachy-brady syndrome.” Sinus node dysfunction may also be accompanied by abnormalities of AV conduction. Another term for sinus node dysfunction is “sick sinus syndrome.”...
متن کاملGenetics and Sinus Node Dysfunction.
Sinus node dysfunction (SND) is commonly encountered in the clinic. The clinical phenotype ranges from asymptomatic sinus bradycardia to complete atrial standstill. In some cases, sinus bradycardia is associated with other myocardial conditions such as congenital abnormalities, myocarditis, dystrophies, cardiomyopathies as well as fibrosis or other structural remodeling of the SA node.1-8 Altho...
