Hi,
Thanks for the query.
As your ECG etc are normal, the symptoms you are having could be due to physiological changes in
pregnancy.
During pregnancy, the
heart rate can increase.
Due to enlargement of the
uterus, abdominal organs will be pushed towards thorax.
This can lead to breathlessness, pain in ribs etc.

Gastritis, regurgitation of the food etc are common findings in pregnancy.
This can lead to heart burn etc symptoms.
By taking measures like:
-Taking the food at more frequent intervals
-Maintaining gap of around 2 hours between food and sleep
-Using antacids if needed etc,
the symptoms can be decreased to some extent.
Take care.
