Accepts healthy volunteers


The investigators thought to explore arrhythmias outcome - hidden arrhythmias, ECG features: Tp-Te interval and Tp-Te/QTc ratio, fQRS among patients with coronary artery ectasia as compared to normal coronary artery patients.


All patients will be subjected to:

  1. Full history taking:
    • Including age, sex, history of DM, HTN, dyslipidemia and Body surface area.
  2. Holter monitoring for 24 hours:
    • Heart rate variability
    • Hidden arrhythmias
    • Hidden ischemia by monitoring ST segment changes
  3. Twelve lead ECG:
    • fQRS in baseline ECG
    • QT dispersion.
    • Tp-Te interval and Tp-Te/QTc ratio
    • Tp-Te dispersion
