Re Cardiac evaluation. Gastro problem?

I went for a Cardiac evaluation as I used to feel palpitations, chest pain sometimes. So had the Echo, TMT done along with ECGs all of which came normal. That was in November. Again, a week ago, I started feeling palpitations while sleeping and on waking up I felt burning feeling or chest pain for a few minutes and then first day the pain was mild and stayed for whole day. So I had ECG, Echo again and current cardiologist prescribed some medicines as he said it might be due to oesophageal spasm. But now after taking medicines Rabprazole 20 mg, Aurinorm-D, Flavedon MR, Neopride since the past 2 days, I am not feeling any pain on waking up from sleep. My palpitations have also become almost neglibible. So, hopefully I don't have heart problem, it might have been just gastro problem?
