May be heart rhythm: Causes for above episodes could include a heart rhythm problem, metabolic/endocrine problem, or possibly anxiety/panic related. An event monitor or holter monitor would be helpful to assess if was a rhythm problem. Your doctor can assess if lab testing or heart echocardiogram (to look at heart structure as a potential cause of rhythm problem) is needed.
