EMG-6L Portable ECG Monitor

1. Introduction

EMAY 6L is a stand-alone ECG recording device with screen and built-in memory.  That’s right, you don’t need a smartphone to make it work ! It allows you to record and review your ECG rhythms on the device itself, and gives you instant analysis in just 30 seconds.

We also provide free apps in case some users want to share ECGs or review details on smartphone/tablet (via bluetooth) or computer (via usb cord). 

What’s more, the device is capable of recording two ECG types:

  • Record a Six-Lead ECG (by placing left & right thumbs against the electrodes on the top surface, and left leg against the electorde on the bottom surface.)
  • Record a Single-Lead ECG (by placing left & right thumbs against the electrodes on the top surface only, without using the bottom electrode.)

Kind Reminder:

Below information is very important, please read them through before recording.

 Important tips to get accurate and quality ECG readings:
  • Stay completely still during the recording. Any movement or shaking might create artifacts and give false reading.
  • DO NOT press or push the electrodes too hard. Gentle touch and contact would be just fine.
  • DO NOT let go of your finger or contact untill the recording finished. There will be timer counts down from 30 to 0 second to complete a recording on the device.
  • If your skin is too try, dampen skin a little bit before recording.
  • Clean the electrodes if they are dirty.
  • Stay away from the other electronic devices such as computer, TV set… before recording ECG.
  • DO NOT use the electrode on a portion of the body with too much body hair or very dry skin, as a successful recording may not be possible.
  • DO NOT use with a pacemaker, ICDs, or other implanted electronic devices.
  • DO NOT use the device while you are charging it.

4. Recording a Six-Lead ECG

Analysis

Description

 

No Abnormalities

Indicates normal sinus rhythm with no rhythm or heart rate abnormalities detected. Your heart rates are from 50-100 beats per minute (bpm)

 

Atrial Fibrillation

 

Atrial Fibrillation (A-fib) is an irregular and often very rapid heart rhythm (arrhythmia) that can lead to blood clots in the heart. A-fib increases the risk of stroke, heart failure and other heart-related complications.

 

Arrhythmia

 

Indicates abnormal heart rhythm, which refers to any change from the normal sequence of electrical impulse. It means that your heart beats too quickly, too slowly, or with an irregular pattern. A-fib is one of the most common type of Arrhythmia.

 

Missed beat

 

Also known as skipped beat, it indicates the heart's regular rhythm is interrupted by a premature or early beat.

 

 

Occasional PVC

 

Premature Ventricular Contraction (PVC), which indicates an extra heartbeat originates in the ventricle and disrupts the heart’s normal rhythm.

Occasional PVC usually isn’t concern in people without heart disease. You might take attention or treatment if the PVC happens frequently.

PVC trigeminy

 

Two normal (sinus) heartbeats followed by one PVC (extra beat)

PVC bigeminy

 

One normal (sinus) beat followed by one PVC (extra beat)

PVC couple

 

Two PVCs in a row

PVC runs of 3

 

Three PVCs

PVC runs of 4

 

Four PVCs

 

PVC RonT

PVC beats so early in the cardiac cycle that it falls on the apex of the preceding T wave

 

Bradycardia

 

A heart rate slower than 50 beats per minute, which is slower than normal for most people.

(Notes: You are able to adjust the device’s threshold for Bradycardia through the EMAY app.)

 

Tachycardia

 

A heart rate faster than 100 beats per minute. There are many heart rhythm disorders (arrhythmias) that can cause tachycardia. However, sometimes this can be normal response to exercise, stress, anger, fear or anxiety.

ST Elevation

 

It refers to a finding on an electrocardiogram wherein the trace the ST segment is abnormally high above the baseline

ST Depression

 

It refers to a finding on an electrocardiogram wherein the trace the ST segment is abnormally lower than the baseline

Invalid ECG

 

The recorded ECG is invalid due to operation error
