What is channel Ecg Machine? and what is ECG Machine Used for?

Posted by Tentabs Tech Solutions Pvt Ltd on

 

An electrocardiogram (ECG) is a medical examination that detects cardiac (cardiac) abnormalities by measuring the electrical activity caused by the heart when it contracts. The device that records the patient's ECG is called an electrocardiogram.

The electrocardiogram records the electrical activity of the heart muscle and displays this data as a trace on screen or on paper. These data are then interpreted by a practicing physician.

The healthy heart ECG has a distinctive shape. Any change in heart rate or damage to the heart muscle can alter the electrical activity of the heart so that the shape of the electrocardiogram changes.
Your doctor may recommend an ECG for people who may be at risk for heart disease because of a family history of heart disease or because they smoke, are overweight, have diabetes, have high cholesterol or high blood pressure.

When Doctors can prescribe an ECG if a person has symptoms such as:

  • chest pain
  • shortness of breath
  • dizziness
  • faint or
  • fast or irregular heartbeat (palpitations).


Usually, ECGs are conducted to monitor the health of people living with heart disease, to help determine artificial pacemakers, or to monitor the heart effects of certain medicines.

The three main types of ECG are:

Resting ECG-
For this sort of ECG, you lie down. During the test, no movement is permitted as the electrical impulses produced by other muscles can interfere with those generated by your heart.. It usually takes 5 to 10 minutes for this type of ECG.


Ambulatory ECG -
If you have an ambulatory or Holter, use a portable recording device for at least 24 hours. You can move normally while the monitor is connected. This type of ECG is used for people whose symptoms are intermittent (initial stop) and may not appear on a resting ECG, and for people who recover from a heart attack to ensure their heart is functioning properly. You record your symptoms in a diary and observe when they occur so that your own experience can be compared to the ECG.

Cardiac Stress Test -
This test is used to record your ECG while riding an exercise bike or treadmill. It takes between 15 to 30 minutes to complete this form of ECG.

An electrocardiogram (ECG or EKG) is the measurement and graphical representation, over time, of the electrical signals associated with the heart muscles. ECG applications range from heart rate monitoring to diagnosis of specific heart conditions. The basic principles of ECG measurement are the same for all applications, but the details and requirements for electrical components vary widely.

How ECG works?

All ECGs capture cardiac signals through electrodes connected externally to specific body locations. Heart signals are generated by the body and have amplitudes of a few millivolts. Specific electrode locations allow the electrical activity of the heart to be viewed from different angles, each of which is displayed as a channel in the ECG printout. Each channel represents the differential voltage between two of the electrodes or the differential voltage between one electrode and the average voltage of several electrodes.

Different electrode combinations allow more channels to be displayed than electrodes. Channels are commonly referred to as "leads," so there are 12 separate channels graphically displayed on a 12-lead ECG device. The number of leads, depending on the form, ranges from 1 to 12. Unfortunately, the wires that run to the electrodes are also occasionally called leads.

Types of ECG Channels

Single Channel ECG

There is one amplification channel and one recording panel in the single-channel ECG module. These devices usually have a multi-position switch, which can be used to pick the desired lead link. With this type of instrument, only one lead at a time can be registered

Three Channel ECG

On 3 channel machines, the ECG signals selected by the microprocessor are amplified, filtered and sent to a 3 channel multiplexer. The multiplexed analog signals are then given to an analog to digital converter which is then stored and sent to the digital to analog converter to reconstruct the analog signals and these signals are demultiplexed and passed to the video monitor or graphics recorder.

Six Channel ECG

6 Channel ECG System prints in one go 6 waveforms. So compared to 3 channel ECG Device, its paper width is wide. Six-channel ECG System print format would be 6x2. 6 Channel ECG The length of the reporting system is comparatively smaller as the width of the page is wide.

12 channel ECG
A 12-lead ECG is an effective clinical decision-making method and can provide a wealth of information such as diagnosis of developing MI; detect life-threatening arrhythmias; long-term effects of persistent hypertension; or acute pulmonary embolus symptoms. Unlike cardiac monitoring, the 12 lead ECG displays the heart's 3-dimensional electrical activity captured from twelve separate leads or points of view. It gives the entire photo. So it's also called an ECG system multichannel. Most of the 12 channel ECG machine is known to print on A4 size paper ECG sheet. And the report is broad and low. It makes it easy for doctors to examine the ECG waveform and compare it.

Use of ECG Channel machine

ECG electrodes are positioned in fixed locations on particular areas of the body so that various images of the electrical activity of the heart can be reliably captured and repeated across records.
  • Check your heart rate
  • See if you have weak blood flow to the heart muscle (this is called ischemia)
  • Diagnose a Heart Attack
  • Check for abnormal things like thickened heart muscle
  • Detect if there are significant abnormalities in the electrolyte such as high or low calcium potassium.
  • If clogged or narrowed arteries in your heart (coronary artery disease) are causing chest pain or heart attack
  • Structural Problems With Your Heart's Chambers
  • A previous heart attack
  • To what extent are ongoing heart disease treatments, such as a pacemaker, working
