Good question, so why don’t you ask that cardiologists? When the pericardium becomes inflamed, the amount of fluid between the heart and the pericardium increases. This squeezes the heart and restricts its action and in his case, may have caused the AF/Flutter.
Btw CAD has not been excluded and could yet be present, but I agree the focus should be on determining the cause of the pericardial effusion, which most likely will recur. Likewise the cause of AF hasn’t been examined (I’d guess the effusion). Further testing will be necessary and may well include a biopsy of his pericardium. In some cases most of the pericardium may need to be removed (pericardiectomy) to prevent further recurrences.
If you believe this answer helped, please consider making a charitable contribution to the Portland Community Free Clinic, which provides free medical care to needy patients in the area.
Hope this helps,
