No, every EKG gets an automatic and instant algorithmic result from our Kardia Instant Analysis. It can give you results like 'Possible AF' and just as important, "Normal".
Premium is not needed to take EKG readings and get Kardia Instant analysis results.
We do offer an optional service to additionally have your EKG sent to our Clinician Review service, where you can have your EKG read by a real life human Clinician. Clinicians can identify many more arrhythmias that Alivecor is cleared to give. (Offerings of review types vary country to country.
Note: If you are a U.S. user your first EKG (and only your first) will have a delay as we process your EKG with a Board-Certified Cardiologist through our Clinician Review service, free of charge. You will be blocked from EKGs for up to 24 hours until it complets. See here for more details.
