POTS is not diagnosed from dizziness or a smartwatch number alone. Learn which symptoms matter, how clinicians compare heart rate and blood pressure after standing, what can mimic POTS, when tilt-table testing helps, and why treatment must be individualized.

The most useful heart monitor is not necessarily the longest one; it is the device most likely to record the rhythm when the patient’s usual symptom occurs.

Living well with atrial fibrillation means reducing stroke risk, managing symptoms, understanding triggers, and knowing which rhythm changes need urgent medical care.
