For normal use in practice ensure the option of "Standard EKG" is selected as per the image above.

The screen will change to a simulated ECG trace paper. Ask the patient to hold the AliveCor mobile
ECG device with their thumbs resting on each of the pads. If the patient struggles with this, they may
rest their fingers on the pads with the AliveCor device resting on a desk.
However the patient holds the AliveCor device, ensure the device is near microphone of your
smartphone or tablet.
The device communicates with your phone or tablet via its built in microphone. This will be where you
speak if using a smart phone or if using a tablet is normally a small hole at the top or bottom edge of the
tablet.
The AliveCor device transmits ultrasonic signals which the phone or tablet listens to. This is then converted
into the ECG on screen.
Some devices may struggle to pick up the ultrasonic signal so try to ensure that you have the patient hold
the mobile ECG close to the microphone on the phone/tablet.
When working correctly you will see the screen change and the ECG trace appear.
In the top left hand corner of the screen you will see green signal bars depicting that the device is
communicating correctly and the quality of the signal. Move the mobile ECG closer if the bars are small to
improve the communication signal.
In the bottom right of the screen is a timer that counts down from 30 seconds. When the timer
reaches zero, the ECG will be interpreted and the results given on screen.
Interpreting the results
Upon completion of the 30 seconds recording, you will be presented with an automated assessment
of the patient's ECG, as shown below.
