Symptom narrative

On May 22, 2024 I experienced an episode of syncope with no prodrome and no apparent cause. I was seated at my desk typing (after eating lunch and drinking fluids), and then I was on the floor with coworkers calling my name to revive me from passing out. They let me know that I was out for ~30-60 seconds. This has never happened to me before. I was taken to the ER to rule out heart- and brain-related causes. No cause was found. One year and two months later, on July 19, 2025, I was sitting at a table eating lunch with friends. I was in the middle of telling a story, and I suddenly passed out with no forewarning or physical signs (e.g., lightheadness, sweating). I was out for ~30 seconds. I regained consciousness in response to my husband calling my name and shaking me. The episode was followed with a persistent headache for about a week. The EKG and brain CT scan with contrast showed no irregularities. I am in the process of being evaluated a cardiologist and neurologist.
