Common questions
Questions about POTS.
What should I track with POTS?
Symptoms like dizziness, racing heart, and fatigue, plus what you were doing, such as standing, heat, or eating. If you check your heart rate, logging it next to symptoms helps show the pattern.
How do I prepare for a POTS appointment?
Bring a record of your symptoms, when they happen, and what seems to trigger them. Specific notes help your doctor more than "I feel awful when I stand."
Can an app help me track POTS?
Yes. Valeska lets you log symptoms and triggers in seconds and builds a clear summary for your visits.
Is there a private POTS tracker that is free to start?
Yes. Valeska is free to start. It encrypts your local record and lets you control what is synced or shared.
Can I track my heart rate and symptoms together?
Yes. If you check your heart rate when symptoms hit, you can log both in one place, which helps show how they move together.
Is there a quick way to start tracking POTS?
Yes. Valeska has a searchable POTS starter pack. One tap adds what people with POTS often track, like dizziness, heart rate, and fatigue, and you keep only what fits you.
