Rule out the Right Ventricular Hypertrophy-

[Pillai]

My son 14 years have an Pediatric ECG analysis. The values and analysis on ECG printout are as follows:-

Age - 14 years, Height - 65 in, Wegith - 146 lb

Vent. rate   -                    65 bpm
PR Interval                      106 ms             - sinus rhythm with premature atrial complexes
QRS duration                   078 ms            - Right Ventricular Hypertrophy
QT/QTc                       402/418 ms          - Possible Biventricular hypertrophy
P-R-T Axes                  70 50 11

I have not yet received the report/ result from the Pediatric Cardiologist.... We are very much upset after seeing the above ECG report... Kindly help as soon as possible ... Are these values within the parameters for a 14 year old boy...? Please advise ..Thank you..

I am wondering what the outcome of this is? Did they do an echocardiogram to confirm if he actually does have right ventricular hypertrophy?

The unfortunate clinical reality is that the ECG is not very accurate as a diagnostic tool for determining chamber enlargement. Even in the best of hands, the sensitivity for detecting LVH (Left Ventricular Hypertrophy) does not exceed 60%.  
That would indicate a false positive at 40%.

Diagnostic accuracy for determining RVH (Right Ventricular Hypertrophy) and atrial enlargement is even less.  Rarely will any one finding clinch the diagnosis.  Instead determination of RVH is most often made by deduction (i.e., from identifying a combination of the following ECG findings):  Such as; Incomplete RBBB (or an rSr' in lead V1), Low voltage (especially if emphysema present),Persistent precordial S waves. Tall R wave in lead V1. EKG requires clinical support and further testing for a diagnosis of an enlarged heart.
  
Echo-cardiography is far superior to the ECG for diagnosing enlargement of any cardiac chamber.
