It appears that you have 3 problems:
1) low heart rate
2) low BP
3) frequent giddiness
Low BP and giddiness may be rather normal in many young Asian ladies (you didn't specify your age). Simple life style measures can improve the symptoms, prevent injury, and most of these young ladies grow out of them over time.
The combination of 3 is more of a concern, unless you are a keen athlete. In addition, there are different types of slow heart rate as shown on ECG; some are serious whereas others are less so.
I would agree with your doctor that you should seek a specialist consult (usually cardiologist).
