Free text: Pre-syncopal, hypotensive episode this AM around 9:10 AM for which we called 911 because I had shaded vision and diminished hearing along with a massive wave of nausea, dizziness, and a feeling like I was going to pass out. It lasted maybe 5 minutes, and subsided after my husband helped me reclined against the couch. My systolic BP was 88, normally it is 100-120. My HR also bottomed out (per Garmin watch) for a few seconds at the time of the episode.

Systemic reaction (other): Pre-syncopal, hypotensive episode this AM around 9:10 AM for which we called 911 because I had shaded vision and diminished hearing along with a massive wave of nausea, dizziness, and a feeling like I was going to pass out. It lasted maybe 5 minutes, and subsided after my husband helped me reclined against the couch. My systolic BP was 88, normally it is 100-120. My HR also bottomed out (per Garmin watch) for a few seconds at the time of the episode.

Each entry is dated by the survey it was written in (the CDC re-sent the releases with survey dates in 2025); click a date to see that survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
