Power spectral and Poincaré plot characteristics in sinus node dysfunction.
A salient feature of the normal sinus node activity is its prominent beat-to-beat variability, which shows self-similarity on different time scales (fractal dynamics). However, in patients with sinus node dysfunction, short-term time sinus cycles show exaggerated variability, the characteristics of which have not been analyzed. Therefore, Poincaré plots and power spectral analysis were applied ...
متن کاملClinical Characteristics of Hypervagotonic Sinus Node Dysfunction
BACKGROUND Sinus node dysfunction (SND) is caused not only by intrinsic sinus node disease, but also by the extrinsic factors. Among the extrinsic factors, autonomic imbalance is most common. Symptomatic SND usually requires permanent pacemaker therapy. However, the clinical characteristics and patient response to medical therapy for hypervagotonic SND have not been properly clarified. MATERI...
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...
