ECG Machine

What is a Resting ECG Machine ? 

An ECG Machine is a cardiology diagnostic instrument that is used by trained operators in a hospital or medical professional’s facility environment, as well as used in clinics, physician offices, outreach centers, or wherever an ECG Test is performed for ECG acquisition, analysis, and recording system. 

What is ECG Test? 

It is a non-invasive method of collecting the data about the heart rate and rhythm of the heartbeat, the presence of any abnormalities or irregularities, and the overall function of the cardiac conduction system by measuring the electrical activity of the patient’s heart. 

How Does an ECG Machine Work, Or What is the Function of an ECG Machine?

Performing an ECG test with modern advance devices is become very easy. 

After setting up an ECG machine according to the instruction manual, which includes machine installation, ECG lead placement on the patient, and entering patient information like age and name into the device, the procedure of taking an ECG test begins with just the press of start button.

The procedure includes:

• Placed ECG Leads detect the electrical signals produced by the heart as it beats.
• The machine filters out noise and interference to isolate the heart's electrical activity.
• After that, the filtered and amplified signals are graphically represented on a display screen or paper strip (ECG Paper) as an ECG tracing.
• Healthcare professionals interpret the ECG tracing to diagnose heart conditions like arrhythmias and ischemia.

Use of purpose of an ECG Machine: 

The main purpose of an ECG device is to acquire, analyze, display, and record information regarding like how the heart is functioning by analyzing heart rate and heart rhythm (condition how regularly heart beats) for patients in a hospital, medical professional’s facility, clinics, physician’s office or outreach centers.

A healthcare provider can ask for an ECG Test to their patients in following cases:  

• To assess Cardiac Health 

• Diagnose heart conditions like arrhythmias, conduction disorders, myocardial infarction, and ischemia.

What are the Channels in an ECG Machine ? 

ECG channels refer to the number of electrical signals recorded simultaneously by an ECG machine.  

Mostly devices come in variant of single-channel, three-channel, six-channel, and twelve-channel.  Some ECG Machine like Rms Vesta 305i and Clarity Truebeat come with 4 channels. Each Device records total 12 leads. 

Single Channel:  Devices with single channel can print one lead at one time. To Print total 12 leads, it prints one by one lead, on the paper. 

They are ideal for routine screenings of a patient. 

3 channel: Machine with 3 channels can print total 12 leads in group of 4x3 at same ECG report means 3 leads at a time.  

They come with more features compare to a single channel ECG machines.

6 channel:  6 channel ECG devices can print the 6 leads at a time and total 12 leads in two slots. 

12 channel:  Most advance ECG Machines, Can print all 12 leads or channel at a time (1x12 Format). Also, can print 3x4, 6x 2 format. Come with advance features like large display, size, large internal memory, arrhythmia detection, multiple printing modes and more.

How much budget do you need to buy an ECG Machine in INDIA:

Cost of a hospital ECG machine vary between Rs. 19000 to Rs. 194000 depending on the desired ECG channels, brand, features.

For Example, a single channel ECG machine will cost you less than a 3 channel and 12 channel ECG device. 

Machine from premium brands will cost you higher, such as BPL 12 channel ECG machine cost you around Rs 98k while Contec 1200G will cost you only Rs, 49500.

And features like high sampling rate, interpretation technology, large display, more filters for noise reduction can increase the cost of an ECG machine. 

Here below categorized the price list of resting ECG machine according to brands and types:

Price List According to the Brands in India: 

 Price List according to channels in India: 

Technical specifications you should keep in mind while buying ECG Machine: 

• Should provide 12 Lead Acquisition 
• Number of Channels
• Check Sampling Rate and AD convertor, More sampling rate and big AD Convertor means more accurate report. 
• Prior to ECG Machine with Screen for digital display of ECG Channel
• At least have Manual and automatic Modes, If it has Rhythm mode, than it butter on bread. Our recommendation is that if you go above single channel, give priority to all three modes. 
• Internal Storage 
• Heart Rate Measurement Range 
• Should have Good Battery Backup 
• Should have Adjustable Recording Speed 
• Should have Built-in interpretation software
• Should with Come automatic adjustable filter settings to minimize noise and interference, ensuring accurate ECG recordings.
• Warranty and Support
• Except these, you can consider Other features like Size, extended warranty and Compatibly with LAN/Wi-Fi/USB, Optional Features like Stress ECG it provides and more.

Buy ECG Machine From Popular Brands In India: 

Schiller Healthcare : You can consider their products as best ECG machines in the India. Their ECG products line include 3 and 12 channel devices which come with high sampling rate and large frequency band.

What are the filters in an ECG machine ?

During ECG procedure, the ECG machine also collects some noise along with heart signals, and it makes the ECG reading unclear. To remove this noise, ECG machines come with built-in filters that help to remove the noise that is outside the normal ECG frequency range, which is usually 0.5 to 150 Hz (Vary product to product). 

In short, ECG filters to remove the noise outside ECG frequency, either it can be low or high from ECG Frequency.

Maintenance and Cleaning of Your ECG Machine: 

Proper maintenance required for long life of your ECG equipment and their accessories. Follow the instruction manual guidelines.

Here are generic instructions:

• Regular cleaning with clean cloth or cleaning wet wipes & sanitization of device. 

• Do regular cleaning of ecg accessories according to instruction manual. 

Inspect ECG Cable and Electrodes regularly and before using ECG, if there is any damage, replace it with new one.
