Kardia has three FDA-cleared algorithms to detect the following conditions and provide users with an Instant Analysis:
Possible Atrial Fibrillation
This is not a diagnosis, but a possible finding based upon algorithmic analysis of your heart rhythm. We encourage you to contact your personal doctor to share this recording, especially if this is the first time you have received this result.
Normal Sinus Rhythm
If no abnormalities are detected in your EKG, you will receive an Instant Analysis finding of “Normal.” This finding indicates that your heart rate is between 50-100 beats per minute and the shape, timing and duration of each beat is considered normal. There is a wide range of normal variability among different individuals, so the Normal algorithm has been designed to be conservative with what it detects as normal.
If you have been diagnosed with a condition that affects the shape of your EKG (e.g., intraventricular conduction delay, left or right bundle branch block, Wolff-Parkinson-White Syndrome, etc.), experience a large number of premature ventricular or atrial contractions (PVC and PAC), are experiencing an arrhythmia, or took a poor quality recording it is unlikely that you will be notified that your EKG is normal.
It is also important to note that the Normal algorithm looks at the entire 30-second recording before determining if it can be declared to be normal. If you experience a small number of PACs or PVCs in a recording of otherwise normal beats in normal rhythm, the Normal Detector will likely declare this recording to be normal.
There are many reasons why you may receive an Unclassified finding. Two common possibilities may be detection of a heart abnormality or arrhythmia other than Atrial Fibrillation, or a heart rate below 50 or above 100 beats per minute. We strongly encourage you to contact your personal doctor if you have questions or concerns about an EKG recording or Instant Analysis finding.
We do not currently have an algorithm that detects other arrhythmias or abnormalities, but your personal doctor or a medical professional trained to read EKGs may be able to detect and interpret another finding upon review of your EKG. You may also send your EKG out to our Clinician Review service where either a Board Certified Cardiologist or Certified Technician will review and interpret your EKG and send a report back to you with their findings.
To send an EKG out for Clinician Review, open the EKG and tap on the envelope icon. Tap on Clinician Review then choose the service you wish to utilize.
