For the past 4 1/2 months, I have been blacking out. During episode, I Urinatie on myself, nausea, stopped breathing, shaking, heart racing.. Been hospitalized test ran EKG,EEG, heart ultrasound... No results except... EKG irregular... Heart cath done... Showed rhythm problem but not enough to place pace maker. Have loop in chest now... No diagnosis, very afraid. Last episode was driving. First three woke up from sleeping. Any insight appreciated
