Sinus tachy rsr v1 and v2 likely normal variety interpretation limited by baseline wander throughout pr interval 122 p front axes 78 qrs duration 104 qt interval326 corrected qt 451 qrs front axis 88 t40 front axis 121 what does this mean is it bad?

Your EKG interpretation should come with an overall conclusion. You don't mention what your heart rate was on the tracing so I can't comment on your heart rhythm which is probably normal sinus rhythm. but I would conclude the following:: There is a right ventricular conduction delay or incomplete right bundle branch block. This is.most often a normal variant & not necessarily a sign of heart disor

All these are normal. Curious as to why an 18 year-old had an ECG? Was a heart abnormality suspected by your doctor?
