My husband just had to leave the store abruptly because he started experiencing dizziness, nausea, instant diarrhea, shaking, sweating, flushed skin, faintness. No pain associated with these symptoms. He experienced something similar to this a few days back, as well. He sees a cardiologist regularly for a family history of heart disease. He has a known LBBB. He is fine now. Should I take him to the hospital anyway?
