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 کاملSinus node paucity in hyperekplexia.
We report a newborn with hyperekplexia and uncontrolled tonic spasms which did not respond to intravenous phenobarbitone and phenytoin, and midazolam infusion. Serum biochemistry, electrocardiography, electroencephalography, lumbar puncture and neuroimaging were normal. Continuous cardiac monitoring revealed that tonic spasm episodes were accompanied by sinus node paucity and severe bradycardia...
متن کاملThe sinus node electrogram rediscovered.
In 1971 Cramer [1] reported the characteristics of unambiguous measurement of sino-atrial conduction time, unipolar electrograms recorded in vitro from the pacethe identification of pacemaker shifts and the extent to maker region of the rabbit sinus node and subsequently which atrial impulses penetrate the node and act on the published similar records from the sinus pacemaker of the pacemaker. ...
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...
