Table 1 Results of sensitivity, specificity and performance

From: Demonstration of value of optimizing ECG triggering for cardiovascular magnetic resonance in patients with congenital heart disease

  False positives False negatives Specificity (%) Sensitivity (%) Performance index (%)
old algorithm (N = 6811) 22 * 63 99.68 99.08 98.75
new algorithm (N = 6802) 0 16 100.00 ** 99.76 *** 99.76
  1. Specificity, sensitivity and Performance Index of detection increased using the new ECG-trigger algorithm compared to the old ECG-trigger algorithm.
  2. * 22 false positive trigger points in three of 35 patients.
  3. ** p = 0.104 vs. old algorithm.
  4. *** p = 0.043 vs. old algorithm.
