“…Secondly we examined it dichotomously at the highest amount of stress compared to the two lower tertiles. Cohen’s Kappa was used to assess inter-scale agreement on perceived stress in tertiles and dichotomously (32, 33). Due to the nonparametric distribution of the data, the Spearman’s rank correlation was used to assess the correlation between the scores of the Assessment of Partner/Other Support and Self Esteem scales from the PPP were tested with the total scores of the PSS and Perceived Stress score of the PPP.…”

Objective Assess the amount of agreement between the classification of stress from the Perceived Stress Scale (PSS) and the Assessment of Stress portion of the Prenatal Psychosocial Profile (PPP) among pregnant women. Methods A secondary data analysis on a cross-sectional study of 301 pregnant women from the New Orleans and Baton Rouge areas who were exposed to Hurricane Katrina was conducted. Women with complete data (219) were analyzed. Women scoring in the third tertile of each instrument were compared. The kappa statistic was used to assess agreement between instruments. Additional comparisons were made with three instruments that measure other important psychosocial constructs that could be related to stress: the Edinburgh Depression Scale (EDS) and the Assessments of Support (partner and other support) and Self-Esteem from the PPP. Results No significant difference was found between the two tests. The PSS and the PPP were both statistically significantly correlated to each other (ρ=0.71, p<.01). Thirty-five women were classified discordantly resulting in a Kappa Coefficient of 0.61 (95% CI 0.50-0.72, p<.01). No significant differences were found between these two instruments in correlation with the EDS (PPP, r=0.76; PSS, r=0.72; p<.01 for each), partner support (PPP, r=−0.47; PSS r=−0.46; p<.01 for each), other support (PPP, r=−0.31; PSS r=−0.32; p<.01 for each) and self-esteem (PPP, r=−0.41; PSS, r=−0.52; p<.01 for each), respectively. Conclusions Given the similarities between the PSS and PPP, researchers are encouraged to choose and administer one instrument to participants, or to use the instruments in combination as an external reliability check.

“…In our study all digital samples were displayed, and the on‐screen calipers measured durations and amplitudes down to 2 ms and 0.05 mV, respectively. Hence, small deflections as T‐wave inversions ≥ 1.0 mm and Q waves ≥ 3.0 mm were easier to detect (Berge et al., ). Third, the visual assessment both on paper and on‐screen has subjective components: where to start and end a measurement and in choice of lead.…”

Electrocardiogram (ECG) and echocardiography are mandatory in preparticipation cardiac screening in soccer players. Abnormal ECG findings usually require follow-up investigations. The main aim of this study was to compare the prevalence of abnormal ECG findings in male professional soccer players according to European Society of Cardiology's (ESC) recommendations and the Seattle criteria, and to assess the need for echocardiography. ECGs from 587 of 595 (99%) players were recorded with ClickECG, and measurements were derived with visually adjusted on-screen calipers on the computer-based averaged PQRST complex. Echocardiographic recordings were performed with Vivid 7/i and categorized according to reference values for athlete's heart. After the initial screening, 32 (5.5%) players were recommended for follow-up. The prevalence of abnormal ECGs was 29.3% vs 11.2% according to the ESC's recommendations and the Seattle criteria, respectively. None of the players with abnormal ECGs only according to the ESC's recommendations had abnormal echocardiograms. Echocardiography alone detected one player with abnormalities (athlete's heart). The Seattle criteria reduced the number of athletes with abnormal ECGs considerably compared with the ESC recommendations. Based on echocardiographic evaluations, this increased the specificity of the Seattle criteria, without increasing the number of false-negative ECGs. The need for mandatory echocardiography in soccer players seems limited.

“…Damit lassen sich sportbedingte EKG-Veränderungen zuverläs-siger erfassen und besser von pathologischen Veränderungen abgrenzen [18,21]. So werden falsch-positive und falsch-negative Befunde deutlich geringer, der prä-diktive Wert des Ruhe-EKG wird erheblich gesteigert [3,4]. Zusätzlich erweist sich die Software-gesteuerte EKG-Analyse anhand der Seattle-Kriterien mit einem entsprechenden EKG-Gerät als genauer (richtiger und präziser; [1, 18,24]) als die visuelle Interpretation [3,4,14].…”

Visual or computer-based measurements: important for interpretation of athletes’ ECG

Abstract: Abnormal ECGs were more than twice as common after computer-based than after visual measurements. Such a difference will markedly influence the number of athletes who need further examinations. Reference values may need adjustments dependent on measurement methods.
