Welcome to Health Care Magic
Hearing the hear beats in only one ear may mean problem with the ear!
Have it checked!
Shortness of breath
may mean lung or heart problem.
If it is on lying down, left heart failure
has to be excluded first.
Of course, some others like asthma
, hiatus hernia
and diaphragm should also be subsequently considered...
Disturbed heart beats too point the need for looking at the heart.
They may at times be normal, but one has to be investigated to be sure.
In summary, you should see your Cardiologist or Internist as soon as possible and get yourself investigated.
Wishing speedy recovery
