sup][30] combined the QRS-T angle with the QRS score and identified high-risk patients with 1-year mortality of 8.
The Selvester QRS score can be applied to the 12-lead ECG once the acute ST-segment deviation has resolved to estimate infarct size in both anterior and inferior ventricular locations.
In this study, we applied the QRS score to patients surviving a first acute myocardial infarction.
Standard 12-lead electrocardiograms were recorded at a 25 mm paper speed for the patients who met the preceding entry criteria had a QRS score calculated from the discharge electrocardiogram on the basis of Q and R wave duration and R to Q and R to S amplitude ratios.
The relation between LVEF and cTnT concentration; LVEF and QRS score was studied using Pearson's correlation coefficient and by systemic analysis of sensitivity and specificity.
When we assessed the relationships between QRS score and the indices of LV function obtained by Echocardiography performed at the time of ICCU discharge, QRS Score was inversely correlated with LVEF (r= -0.
Table IV shows the relation between QRS Score and LVEF.
The QRS Score of > 6 predicted a left ventricular ejection fraction of < 50% with a sensitivity of 79.
The researchers used the total QRS score to take measures of parenting stress at Time 1, which indicated a mean score of 28.
The researchers took measures of parenting stress that used the total QRS score at Time 1, when the results revealed a mean total QRS score of 24.
Table 6 shows the semipartial correlations between parenting stress (as measured by the total QRS score and the total PSI score) and each of the child behavior problems (as rated by the DBC), autistic severity (GARS total score), intellectual functioning (BAS general cognitive ability score), and adaptive behavior (VABS composite score) at Time 1.
To obtain an indication of the possible temporal precedence between parenting stress and child behavior problems, the researchers split the sample into lower and higher parenting-stress groups on the basis of the total QRS score (lower stress, n = 46, mean QRS = 18.
