Family History of Hypertension Impairs the Autonomic Balance, but not the Endothelial Function, in Young Soccer Players by Walter Vargas (6798635)

“…The significance level adopted in the statistical analysis was 5%. Results The standard deviation of normal RR intervals (SDNN; FM-N=314±185; FM-H=182.4± 57.8), the square root of the mean squared differences in successive RR intervals (RMSSD; FM-N=248±134; FM-H=87±51), the number of interval differences of successive NN intervals greater than 50ms (NN50; FM-N=367±83.4; FM-H=229±55), the ratio derived by dividing NN50 by the total number of NN intervals (pNN50; FM-N=32.4±6.2; FM-H=21.1±5.3) and the high (HF; FM-N=49±8.9; FM-H=35.3±12) and low-frequency (LF; FM-N=50.9±8.9; FM-H=64.6±12) components, in normalized units (%), were significantly lower in the FM-H group than in the FM-N group (p<0.05). …”

EFFECTS OF ADAPTED CANOEING ON THE CARDIOPULMONARY SYSTEM OF PARAPLEGICS by Elizângela Márcia de Carvalho Abreu (6147902)

“…Results: After training there was no significant increase in RR (12.7%), SDNN (24.3%), rMSSD (50.0%), pNN50 (478.6%), LF (ms²) (53.3%), HF (ms²) (158.8%) SD1 (50.6%), SD2 (23.2%) and SampEn (20.2%). …”

Supplementary Material for: Risk factors and heart rate variability associated with left ventricular enlargement in patients with frequent premature ventricular contractions by Yang Z. (4129039)

“…The values of SDNN, standard deviation of the averages of NN intervals in all 5-min segments, the square root of the mean of the sum of the squares of differences between adjacent NN intervals, pNN50, low-frequency power (LF), LF/high-frequency power ratio of patients were significantly decreased after ablation (all p<0.05). …”
