Can a portable EKG replace seeing a cardiologist?

No. Portable EKGs are screening tools that help detect potential issues. A positive finding (detected AFib, for example) requires confirmation with a clinical EKG and cardiologist evaluation. Use portable EKGs to capture symptoms when they happen — bringing a recording of your heart during palpitations is invaluable for your doctor's diagnosis.

How often should I record an EKG at home?

For general screening: once weekly or when you feel symptoms (palpitations, dizziness, chest discomfort). For diagnosed AFib: daily or as directed by your cardiologist. Always record during active symptoms — a 30-second recording during palpitations is worth more diagnostically than 100 recordings during normal rhythm.
