Dizziness and lightheadedness, made clear.

Lightheadedness feels like you may faint. Vertigo feels like spinning. Imbalance means feeling unsteady. Describing the sensation helps your clinician find the cause.

Slow heart rhythms are one possible cause, not the explanation for every dizzy spell.

Symptoms may occur after standing, during an abnormal heartbeat, or after a medication change. A monitor can look for a rhythm change during an episode.

Record what you were doing and how long the episode lasted.

Sit or lie down safely. Avoid driving, climbing, or walking unsupported while you feel unsafe. Ask your care team about recurrent or unexplained episodes.

Do not change heart medicines or start extra salt or fluids without checking your care plan.
