Dysfunction of sinoatrial heart node and clinical analysis of heart rate variability
Purpose of assessments was evaluation of peripheral autonomic dysregulation in sinoatrial heart node (SN) by high-resolution analysis of heart rate variability (HRV) in patients with coronary artery disease. Results of HRV analysis in Time-Domain and Frequency-Domain were compared in patients with regulative sinus dysfunction (DFSN) and in patients with sick sinus syndrome (SSS) -270 and 92 patients, correspondingly. There were found symptoms of autonomic dysregulation for difference between DFSN and SSS. HRV-analysis contains possibilities for evaluation of hemodynamics value of each cardioarrhythmic episodes, and also for evaluation of arrhythmogenic background.
