It could be anything. Or sometimes it can also be normal without any abnormality.
Your blood pressure and heart rate are within normal limits. It is good that you dont consume alcohol or smoke.
However I would suggest you to get ECG, 2D ECHO and USG Abdomen done.
These test can rule out aortic regurgitation or abdominal aortic aneurysm.
