The Relationship between Heart Rhythm Variability and the Heart Rate in Adolescents and Young Adults

Abstract

In this article, we study the degree of dependence of heart rate variability in healthy adolescents and young adults on the average rhythm frequency. In the study group, heart rate variability decreased as heart rate grew. Although there was no difference in the increase in the heart rate, the variability of the heart rate decreased less significantly in young women than in young men. An increase in the average heart rate by 10 cardiac cycles per minute reduced the heart rate variability by 25.6 ms in young men and by 14.9 ms in young women. We believe this to be a result of differences in the hormonal backgrounds within the study groups.

Accidental Detection of Cardiac Lipomas

Abstract

In this work, we present a clinical case. A woman (57 y. o.) was referred to echocardiography because of arrhythmia and a cardiac lipoma was accidentally detected. This case is of interest due to the rarity of this cardiovascular disease. The patient was not treated surgically because of high risks associated with such a treatment. This case emphasizes the importance of meeting the standards of specialized medical care when atrial fibrillation and flutter are concerned.
