[Histographic analysis of the heart contraction rate during Holter monitoring of patients with arrhythmias].

Heart rate histograms were analyzed during 24-hour Holter monitoring in patients with cardiac rhythm and conduction disturbances. The profiles of histograms in the most common cardiac arrhythmias: extrasystole, chronic supraventricular reentry tachycardia, atrioventricular block, sinus tachycardia, sick sinus syndrome and those in patients with implantable pacemakers were shown. Approaches to analyzing histograms were defined in Holter monitoring, the histographic analysis was demonstrated to be of value in the comprehensive evaluation of Holter monitoring findings.
