Overview

The study demonstrates the association of fragmented QRS with severe coronary stenosis in patients, suggesting diagnostic potential.

Key Points

  • The aim is to evaluate the association between fragmented QRS and severe coronary stenosis as observed in coronary CT angiography.
  • Analyzed ECG findings of patients undergoing coronary CT angiography.
  • Focused on the predictive value of fragmented QRS for significant coronary stenosis.
  • Identified stenosis levels of ≥70% as significant for the analysis.
  • Fragmented QRS is associated with ≥70% stenosis in coronary CT angiography.
  • The presence of fragmented QRS can help predict severe coronary artery blockages.
