Welcome to Health Care Magic
Gurgling sounds usually emanate from the intestines.
They are at times heard / felt - in the abdomen - at times in the chest...because the chest and abdomen are just separated by the diaphragm. The liver
is immediately below the diaphragm on the right / stomach (& colon
) on the left - hence the feeling more on left.
There could be other causes for chest gurgling, but they are rare and have other associated pointers...
Go ahead with the EKG, Stress test
and Holter for definite conclusions
Wishing speedy recovery
