Part I - ECG DEVICE
1. Introduction
The EMAY Portable ECG Monitor is a stand-alone device intended to record and store Lead I ECG signals, and display heart rate for home health care use. It records your 30 seconds’ ECG and heart rate easily between two hands. The intended users are adults above 20 years old. This device is not intended to substitute for a hospital diagnostic ECG device.
Users with implanted pacemaker are not recommended to use this device.
WARNING: This device is intended for heart activity performance reference for initial evaluation only, not for medical diagnostic use.
Please contact your healthcare provider immediately or go to nearest hospital if any cardiac symptom occurs.
2. Package Contents
The Package Contains:
- ECG Monitor * 1
- USB Cable * 1
- User Manual * 1
3. How to Use
3.1 Sketch
Choose one of the four ways to record your ECG.
W1 and W2 are the recommended ways.
|
IMPORTANT TIPS TO GET QUALITY AND ACCURATE ECG RECORDING: 1) Stay completely still during the recording especially your hands. We suggest you sit down and place your hands on the desk to keep them steady. Any movement might cause false diagnosis and artifacts (very important!!. 2) Ensure your skin is in full & consistent contact with the metal electrodes on both ends of the device untill recording completed. Don't let go of your finger or hand during the recording. 3) DO NOT press the electrodes too hard. Gentle touch and pressure would be just fine. 4) If your skin is too dry, wipe them with disinfectant alcohol, saline or gel to strengthen the electric conductivity and recording efficiency before recording. 5) Clean the metal electrodes if you haven't used the device for some time to avoid artifacts. |
(Do not use the device when it is charging)
• Turn on the device by pressing the power button firmly for 3-5 seconds.
• Hold the device using one of the fours ways mentioned to start your personal ECG journey.
• Once you touch the metal electordes on both ends of the device, a few seconds of "Orange" ECG rhythm will display, which means it's preparing.
• When the signal becomes stable, the rhythm will trun to "Green" and the real recording begins. It will record a 30 seconds' ECG each time.
| Note: We provide two ways for you to download the data, view the ECG rhythm and share the reports with your doctor. 1. APP (iOS & Android) on smart phone -> refer to Part 2. 2. PC Software (Windows & Mac) on computer -> refer to Part 3. |
4. Diagnostic Results
There are 12 kinds of cardiac situations that could be detected:
| No abnormalities | Cardiac performance is normal, no abnormality was detected |
| Arrhythmia | An arrhythmia is an abnormal heart rhythm, during which the heart can beat too fast, too slow, or with an irregular rhythm. Some arrhythmias are harmless, but some can be serious or even life threatening. Atrial fibrillation (A-Fib) is one of the most common arrhythmia. When the device detects Arrhythmia, it doesn't necessarily mean you have A-fib. It could be something else. Please turn to your professional healthcare provider for further diagnosis if it was detected. |
| Tachycardia | A heart rate that's too fast - above 100 beats per minute |
| Bradycardia | A heart rate that's too slow - below 60 beats per minute |
| Missed beat | Skipped beat, the heart's regular rhythm is interrupted by a premature or early beat, it can be caused by premature atrial contraction (PAC) or premature ventricular contraction (PVC) |
| ST elevation | ST elevation refers to a finding on an electro-cardiogram wherein the trace in the ST segment is abnormally high above the baseline |
| ST depression | ST depression refers to a finding on an electro-cardiogram wherein the trace in the ST segment is abnormally lower than the baseline |
| Accidental VPB VPB trigeminy VPB bigeminy VPB couple VPB runs of 3/4 VPB RonT | Different kinds of Ventricular Premature Beat (VPB), also known as Premature Ventricular Contraction (PVC), which is is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node, the normal heartbeat initiator. |
5. Battery

6. Trouble Shootings
6.1 How to set the time/date of the device?
Connect the device to the app or pc software, its time/date will be updated automatically
6.2 Device is hard to turn on?
Keep pressing firmly right at the center of the power button for 3-5 seconds.
6.3 It's difficult to pick up the heart rate and waveform?
Or it takes long time to turn to "Green" official recording?
Please follow below instructions :
a. Dampen your hand or contact spot with alcohol or saline before using.
b. Calm and relax for 5-10 mins before using (If possible)
c. Stay still as much as you can during recording.
d. Do not press the metal electrodes too hard, just gentle and full touch/pressure would be fine.
6.4 The results seem inaccurate, inconsistent or too many artifacts?
Please follow "IMPORTANT TIPS" on page 4 and measure a few times in a row to analyze comprehensively.

2. Trouble Shootings
2.1 Software can't recognzie/detect the ECG device?
Please turn on the device by pressing the play button for 3 second and click "New search" quickly within 10 seconds. Only when the device & screen is ON can it be recognized and operated.
If above instruction doesn't work, plug and unplug the cable for 2 times OR use another usb cable to try again. If neither of above helps, please contact us immediately at service@emaycare.com, we will help you fix it.
2.2 Waveform/Tracing Disappeared
If you have started the software, downloaded the recordings, and found that there's only heart rate data without any waveform, please contact our service team immediately and we will fix it for you.
2.3 Download failure or only part of the reports was downloaded?
There are multiple reasons for this, please try below measures:
- use another USB cable to connect the device to the PC software to avoid a USB cable defect. Any standard micro USB for smart phone should be fine.
- try another USB port on the computer in case the one you ofenly used is loose or defective.
- Uninstall and reinstall the software to make sure the software is well installed
- it could also be hardware defect, if all above methods do not work, please contact us for replacement or return.
2.4 The "Check time" shows "2015-01-01"?
The "Check time" of the first couple recordings might show "2015-01-01", but once the device is initially connected to your computer, the time & date of your future recordings will be correct.
2.5 Can I download the same report to both phone app and PC software?
If you donwload the report to the app on phone first, you can still download it again on pc software, just remenber to tick "All" button on the top of the interface on pc software. However, if you download the report to pc software first, then you won't be able to download again on phone app.
That's why we suggest downloading all reports to your smart phone first.
