Unclassified
Your EKG does not fall into
the algorithmic classifications
of Normal, Bradycardia,
Tachycardia, or Atrial
Fibrillation. This result may
be caused by other
physiological condition (for
instance other arrhythmias,
very fast or slow heart rates)
or may be a result of poor
quality recordings.
This is not a diagnosis, only
a possible finding. Contact a
physician if you have
questions or are concerned
about any symptoms. Record
another EGK within hours or
days of this recording.
Unreadable
There is too much
interference in this recording.
Record a new EKG. Try to
relax and hold still, rest your
arms, or move to a quiet
location with less
interference.
WARNING:
After ECG analysis, the app may incorrectly identify ventricular flutter,
ventricular bigeminy, and ventricular trigeminy heart conditions as unreadable. Please
consult with your physician.
Heart Rate
Current heart rate is displayed during an ECG recording and the average heart rate is displayed
in completed ECG recordings along with the ECG Analysis.
The Kardia App has an internal QRS detector that is used to measure the heart rate, defined as
the inverse of the R-R time interval. During an ECG recording, the current heart rate is measured
from an average of this inverse calculation over the last 5 seconds.
For stored ECGs, the average heart rate is the average of this inverse calculation over the entire
30 seconds of the recording.
Previously Recorded ECGs
From the Kardia app home screen, tap
History
to access previously recorded ECGs.
