Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You are 47 years old female, got hypothyroid, and
mitral valve prolapse, experiencing palpitations in
gallbladder area since 2 months. present through out the day when lying down, or else getting some times. some times heart burn, one and half year back you had echo then everything is O.K.
One and half year back you had
echocardiogram ind it was O.K. means then it was compensated, but probably due to your diet habbits like excess salt, junk foods, oily foods, or increase in your weight, can cause decompensation of the heart, and palpitation. That you may feel in the stomach. Heart burn also may be due to enlarged
liver due to heart problem.
As you have heart burn it also can mimic palpitation.
I advise you to
consult a cardiologist for diagnosis and treatment. You may need to have echocardiogram besides other routine tests for confirmation.
Wishing for a quick and complete recovery.
Best regards.
