Atrial Fibrillation (AFib)
Atrial fibrillation is an irregular rhythm that may cause palpitations or no symptoms. Treatment addresses stroke risk, symptoms, and heart health.

Dizziness and Fainting (Syncope)
Fainting can be harmless, but it can also signal a heart-rhythm or structural problem. The circumstances around an episode guide testing.

Palpitations and Arrhythmias
Palpitations describe what a heartbeat feels like. A monitor can help determine whether the cause is benign extra beats or a meaningful arrhythmia.

Postural Orthostatic Tachycardia Syndrome (POTS)
POTS is a form of orthostatic intolerance that causes excessive heart-rate rise and symptoms while upright without another sufficient explanation.
