VitalSignum Oy assumes no responsibility for the correctness of the measurement
results or any procedures carried out based on said results.
1. Taking Beat2Phone into use for the first time
Charge the Beat2Phone device (heart sensor) with the Beat2Phone charger. Plug
e.g. a phone charger that has microUSB-B connector into the Beat2Phone
charger. Charging time is approx. 1h. The device is fully charged when the red
light turns off.
Install Beat2Phone application on your phone from Google Play Store. You phone
must have an Android operation system 4.33 or higher.
It is recommended that you keep the Bluetooth activated on your phone always.
Start Beat2Phone application. Grant the two permissions requested: in order to
run Beat2Phone must have permission to read and write files. If you want get
GPS data in outdoors spots, grant permission for location also.
In the initial menu, press SETTINGS and then Profile. Give the information by
pressing the items. The last item Username is important. Beat2Phone organises
the recorded data according to the Username. Every user must have an
individual Username. It is recommended that the Username has exactly three
characters; only a-z, A-Z, or 0-9 are allowed. If username is not given, nnn is
used. Press the back-button of the phone to go to the initial menu.
Shake the heart sensor to turn it on. (Heart Sensor has no switch.)
On Beat2Phone initial menu, press START RECORDING. Wait a moment until a
smaller window appears on the screen. The window lists the names and MAC
addresses of all the active Beat2Phone devices nearby (this may take even a
minute). As soon as device name b2p BLE 0.1 with MAC address identical with
that of your Heart Sensor given on its label tag appears, touch the name text. In a
few seconds, the phone should make a connection to the Heart Sensor and
signals appear on the screen. Now the Beat2Phone application is paired with your
Heart Sensor. Later it makes connection to your Sensor automatically after
pressing START RECORDING.
Press the phone’s back button twice to close Beat2Phone application.
2. Taking electrocardiogram, ECG
Adjust the length of the strap to fit around your chest. The strap should stay firmly.
Moisten the electrodes of the strap with tap water, saliva or ECG electrode paste.
This is necessary to obtain a high-quality ECG signal.
Tie the strap around your chest as the ordinary heart rate belts. Shake the sensor
to turn it on and attach it on strap’s snap fasteners. Check that the heart logo on
the sensor is not upside down. (See Fig. 1)
Start Beat2Phone application on the phone.
Press START RECORDING
You should see ECG in millivolts (white), Heart Rate in beats per minute (yellow), and
Heart Rate Variability (HRV) in milliseconds (RMSSD, Root-Mean-Square-ofSuccessive Differences) (red), see Fig. 2. You can select the curves you want to see
via SETTINGS button (at lower right). ECG may be zoomed in and out both

horizontally and vertically, HR and HRV only horizontally with two-finger gestures.
You can move ECG with one-finger sweeps up and down.
The data goes into files on the phone’s internal SD card. (Unfortunately, writing to the
external SD card is prohibited from Android 4.4 on). Each recording is labelled with
date, time (hour, minutes), Username, and 4 last digits of Heart Sensor’s Bluetooth
MAC address for later analysis. The data is stored into a folder
Beat2Phone/Recordings/nnn, where nnn is the Username given in the Profile. Each
recording creates in this folder a new folder named according to date and time:
yyyy_mm_dd-hh_MM_.
When recording, the following buttons on the right are active on the screen (from top
down, see Fig. 2):
Event button allows making an event on the recording if you have symptoms or want
to make a comment. You can select from the list four symptoms or by pressing
Comment you can type your own event. A light blue circle on the heart rate curve
indicates the time point the event was made at.
Stop button stops recording (alternatively press the back-button of the phone).
History button (magnifying glass) starts analysing the data.
Settings button (lowest one) opens a view to change Profile and select which data
are shown on the screen:
Heart Rate (When checked heart rate in shown.)
HRV (When checked heart rate variability is shown.)
ST analysis (ST segment levels of the ECG are computed; not active if
recording is on)
Posture (When checked, 3 acceleration signals are shown on the screen
indicating the posture and activity of the person. On the upper left corner is
shown the head (grey) and nose (red) of the user viewed from the right,
indicating the posture of the user.)
GPS data (When this is checked, Beat2Phone goes into sports mode and
GPS data (latitude, longitude, altitude, and speed) is also recorded. This
should not be checked if only ECG is taken.). The altitude is calculated from
the phone’s pressure sensor data if it is available.
Heart Rate Histogram (When this is checked, Beat2Phone shows histogram
of the HR in the analysis mode.)
Scales (When checked scales of the signals are shown on the screen. ECG
scales are not shown when Posture is checked.)
Grid (When checked vertical and horizontal scale lines are shown on the
screen. Small div = 1 mm.)
ECG 50Hz notch filter (50Hz noise is removed from the real-time ECG)
When you want to stop the recording press Stop button, confirm, and close the
Beat2Phone application by pressing back button of the phone on the initial menu.
