1. Know Your Monitor
Normal means that the heart rate is between 50 and 100 beats per minute, there are no or very few abnormal beats, and the
shape, timing and duration of each beat is considered normal sinus rhythm. It is important to remember that there is a wide
range of normal variability among different individuals. Changes in the shape or timing of an ECG might be normal for a single
individual, but since the apps are used by a large and diverse population, the Normal detector 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 ECG (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 ECG is normal.
It is also important to note that the Normal detector looks at the entire signal 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 that ECG recording to be normal.
The Normal detector will not declare an ECG outside the heart rate of 50-100 beats per minute as normal, even if the ECG
has normal sinus rhythm. As a result, if you typically get normal results but take an ECG immediately after any
physical activity that raises your heart rate above 100 beats per minute, you may not get a normal result.
Unreadable detector
The Unreadable detector determines whether a recording can be accurately interpreted or not. After recording an ECG, if
interference is detected you will be notified within the app that your recording has "No analysis" and given some suggestions
for acquiring good quality ECG recording. You subsequently have the option to save the recording, or try again. If the
recording can be analyzed, the Atrial Fibrillation, Bradycardia, Tachycardia and Normal detectors will run on the ECG and
inform you as described previous pages.
Unclassified
The app may display the Unclassified message for an ECG recording that was not detected as normal, nor as possible atrial
fibrillation, nor as bradycardia, nor as tachycardia, and not as unreadable.
