Sinus arrhythmia is common and it may be detected by EKG at times. Borderline right axis deviation is also common at your age, nothing to concern.
Note that the word "unconfirmed" is added to the report. The second ECG states "rightward axis" when compared to the first ECG. An apparent change in the axis may have been caused by incorrect lead placement by the technician. Review of the ECGs by an experienced internist or cardiologist is necessary for further interpretation and resolution of this question. Good luck.
