[Analysis of cardiac rhythm variability in patients with sinoatrial node dysfunction].

Klinicheskaia meditsina, 2010
The study was designed to elucidate the wave structure of heart rhythm variability (HRV) for the assessment of vegetative regulation of pacemaker activity of the sinoatrial node in 362 patients with coronary heart disease. The results were compared with the data of routine cardiologic examination.

[Lengthening of the direct sinoatrial conduction time: a criterion of sinus node dysfunction].

Archives des maladies du coeur et des vaisseaux, 1984
In order to determine the significance of prolongation of the direct sinoatrial conduction time (DSACT), an attempt was made to record the sinus node potential in 110 patients which was successful in 84 cases. The DSACT was normal in 45 cases (Group A) and prolonged (over 130 ms) in 39 cases (Group B).
