Re: Wife has a heart "squeak or tap."
I would first check her thyroid. The tests by doctors will not tell you much. You may want to take her basal temperature for one week. If her basal temperature is below 96 degrees she has hypothyroid, which leads to heart problems.
What is her diet? If she can be on raw fruits and vegetables that will help her with micronutrients to build her health.
Vomting everyday sounds some issues with the digestive system. Has she done any colon cleanses? I would also look in to Liver Flush. Apply warm castor oil on her abdomin two times a day with a light massage. And do the same for any pain areas. Dr. Christopher has a good heart health Hawthorn Berry syrup, which you can have her start right away.
You can also do stomach acid strength test. You can search here on CZ about that. If the stomach acid is weak, it can have domino effect on many other areas of our body.
If you can find an ND in your area that would be best. Conventional doctors are pill pushers and trial and error method experts.
I feel for you both.
