Condition(s) studied

Post Tetralogy of Fallot Repair Arrhythmias and Echocardiographic Changes

Investigational drug(s) / intervention(s)

echocardiography , 12-lead ECG and Holter ECG

echocardiography , 12-lead ECG and Holter ECG: Holter ECG is used for recording electrocardiogram for long duration varying from hours to days. Echocardiography is used for detecting anatomical and functional defects in the heart.

Study summary

Aim of my study is to detect echocardiographic, ECG and Holter changes in children who have undergone surgical repair of Tetralogy of Fallot. It is a retrospective observational study which will be conducted in Sohag university hospital. Age group of patients included in the study varying from 1 day up to 25 years old.

Inclusion Criteria: * Children and adolescents up to age of 25 years old who have undergone surgical repair of Tetralogy of Fallot. Exclusion Criteria: * Ptients above age of 25 years. * Children with other medical diseases.

Primary outcome measure(s)

  • QRS duration on 12-lead ECG in patients post Tetralogy of Fallot surgical repair — Data will be collected over 1 year period starting after approval of protocol by medical research committee of Sohag faculty of medicine.
    QRS duration measured in milliseconds using a standard 12-lead electrocardiogram
  • Corrected QT interval (QTc) on 12-lead ECG in patients post TOF surgical repair — Data will be collected over 1 year period starting after approval of protocol by medical research committee of Sohag faculty of medicine.
    QTc is measured in milliseconds using standard 12-lead electrocardiogram to detect if it is prolonged or not.
  • Presence and frequency of arrhythmias on Holter ECG in patients post TOF repair — Data will be collected over 1 year period starting after approval of protocol by medical research committee of Sohag faculty of medicine.
    Holter ECG helps in detection of arrhythmias as presence of ectopics
  • Severity of pulmonary regurgitation by echocardiography in patients post TOF surgical repair — Data will be collected over 1 year period starting after approval of protocol by medical research committee of Sohag faculty of medicine.
  • Right ventricular function by echocardiography in patients post Tetralogy of Fallot surgical repair — Data will be collected over 1 year period starting after approval of protocol by medical research committee of Sohag faculty of medicine.
    Right ventricular contractility and enlargement measured by echocardiography to detect if patient is in heart failure or not.
