Anyway, before coming to this conclusion, I would recommend performing some tests:- an ambulatory 24-48 hours ECG monitoring in order to examine her heart rhythm trends for a prolonged time and exclude possible cardiac arrhythmia-pulmonary function tests in order to exclude a lung disorder-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance. You should discuss with her doctor on the above tests. Hope I have answered your query. Let me know if I can assist you further.
