cardiac anomaly (1). SVA most commonly originates in the right coronary sinus of Valsalva (75-90%), the noncoronary sinus (10-25%), and rarely, in the left sinus (1, 2). Unruptured SVA usually remains asymptomatic, but it can sometimes cause cardiac arrhythmia, myocardial ischemia, or systemic embolic events (1-3). Multidetector computed tomography (MDCT) is a useful modality for examining the ...

To investigate the interindividual differences in respiratory sinus arrhythmia (RSA), recordings of ventilation and electrocardiogram were obtained from 12 healthy subjects for five imposed breathing periods (T(TOT)) surrounding each individual's spontaneous breathing period. In addition to the spectral analysis of the R-R interval signal at each breathing period, RSA characteristics were quant...

We applied the respiratory sinus arrhythmia (RSA) quantification algorithm to 24-hour ECG recordings of Chagas disease (ChD) patients with (G1, n=148) and without left ventricular dysfunction (LVD) (G2, n=33), and in control subjects (G0, n=28). Both ChD groups displayed a reduced RSA index; G1=299 (144-812); G2=335 (162-667), p=0.011, which was correlated with vagal indexes of heart rate varia...

Although suicide attempts (SA) occur across a broad range of diagnoses as well as in the absence of a diagnosable disorder, most studies to date have focused on them within a single, specific disorder. Consistent with the NIMH RDoC initiative to identify biobehavioral vulnerabilities that cut across diagnoses, the goal of the present study was to examine potential differences in resting respira...

to explore the abnormalities in iranian athletes' electrocardiogram and find any relation with body fat. 239 international athletes were involved in this cross sectional study. body-fat percentage and resting 12-lead ecgs were recorded from all participants. of 239 participant athletes, 212 were male and 27 female. 60% of participants had sinus bradycardia. a total of 84% of the athletes demons...
