Normal Heart Rate Variability in Colchicine-Resistant Familial Mediterranean Fever Patients.

Background: The relationship between autonomic nervous system (ANS) dysfunction and familial Mediterranean fever (FMF) is controversial. We recently reported normal heart rate variability (HRV), suggestive of normal ANS, in patients with uncomplicated FMF.

Objectives: To evaluate ANS function in colchicine non-responders by using the HRV tool.

Evaluating reliability of ultra-short ECG indices of heart rate variability in diabetes mellitus patients.

Our aim was to investigate the reliability of ultra-short HRV in patients with DM. A good correlation was found between the 1 minute and 5 minute parameters for maximal-RR, minimal-RR, average-RR, SDNN, RMSSD, pNN50, and total power. Also, a good correlation between 10 second and 5 minute parameters was found for maximal-RR, minimal-RR, average-RR, and RMSSD.

Normal QT dispersion in colchicine-resistant familial Mediterranean fever (FMF).

The association between familial Mediterranean fever (FMF) and subclinical cardiac disease remains controversial. The aim of the current study was to evaluate whether FMF patients, who do not respond to colchicine treatment, and thereby endure persistent inflammation, have increased QT dispersion (QTd) values. Twenty-two FMF patients and 22 age- and sex-matched control subjects were included in the study.

Medically treated anorexia nervosa is associated with normal P wave parameters.

Anorexia nervosa (AN) is an increasingly common medical condition. Some studies have demonstrated an increased prevalence of atrial premature contractions and anatomical changes in AN patients. Our aim was to investigate P wave parameters and P wave dispersion, an electrocardiographic marker for supraventricular arrhythmias, and its effect on AN.

QT interval variability in familial Mediterranean fever: a study in colchicine-responsive and colchicine-resistant patients.

The association between familial Mediterranean fever (FMF), early atherosclerosis, and electrocardiographic markers for arrhythmias remains controversial. There are conflicting results as to the occurrence of high QT dispersion in FMF. The aim of the present study was to further investigate repolarization dynamics and other repolarization-associated pro-arrhythmogenic markers in FMF patients.
