The Principle of Operation of an ECG machine:-

ECG is the waveform of bioelectrical changes on the skin which are caused by the successive stimulation from pacemaker to atrium and to ventricle in each cardiac cycle and which are detected and displayed by the electrocardiograph. ECG is the objective indicator of the generating, conduction and recovery process of cardiac stimulation.

The synchronous electrocardiograph is highly praised as the machine of detecting ECG by the clinic medicine at home and abroad, which can synchronously gather the ECG signal on skin from multiple channels and realize inputting multichannel signals synchronously, and therefore the electrophysiological characteristics of every part of the heart during each cardiac pulse can be observed easily, which is conducive to the diagnosis of diseases concerning cardiac nerve conduction and cardiac dynamics.

An ECG machine monitors and records the electrical activity of the heart. ECG machine, also known as an electrocardiograph.

ECG Machine Type and ECG Machine Price Range : 

There are many types of electrocardiogram machine, and it's important to know which one best suits your needs when looking for the best ECG machine for the hospital. Here's a guide to help you understand the various types of ecg test machine available in the market.

1) Single Channel ECG Machine:  Single Channel ECG machine is basic ECG Machine that prints single ECG waveform /channel at a time. Like this type ECG Machine's paper has space for only single trace at a time. So, All 12 channels  of ECG Machine report will be printed one by one on the paper. However, nowadays single channel ECG machine comes in automatic modes. So, it will print all 12 channel automatically one by one without manually changing the leads. Most single channel ECG machines use 50 mm paper width. BPL ECG Machine 6108 is example of the single channel ECG machine.  Single ECG Machine Price range is INR 15,000 to INR 35,000.

2)  3 Channel ECG Machine: As the name suggest, 3 Channel ECG Machine print 3 waveforms/channels at a time. It means the total 12 waveforms will be printed in 4 sections. This report format is called 3x4 format. 3 Channel ECG Machine also print a rhythm lead in some cases. Major 3 channel ECG machines use ECG Paper of 80 mm -90 mm width.   It depends on the ECG Machine model and price. 3 Channel ECG Machine Price range is INR 25,000 to INR 50,000.

3) 6 Channel ECG Machine : 6 Channel ECG Machine prints 6 waveforms in one go. So, its paper width is wide as compare to 3 channel ECG Machines. So, print format of 6 channel ECG Machines would be 6x2. 6 channel  ECG Machine report length is comparatively less because page width is large. 6 Channel ECG Machine Price range is INR 35,000 to INR 65,000. 

4) 12 Channel ECG Machine: 12 channel ECG Machines can print 12 waveforms simultaneously. 12 channel ECG can print in 6x2 and 3x4 formats. So, it is also called multichannel ECG machine. Most of 12 Channel ECG Machine are known to print ECG report on A4 size paper. And Report is wide and paper length is less. So it is easy for Doctors to analyse and compare the ECG waveform. 12 Channel ECG machine use 210 mm to 216 mm wide paper.   12 Channel ECG Machine Price range is INR 50,000 to INR 120,000.

ECG Machine working Modes types :

A conventional ECG Machine have 3-4 working  Mode .

1. Automatic : Under the automatic working mode, the lead groups will be switched in order automatically in the recording of ECG, which means that when the ECG signal of one lead group has been recorded in the set period, it will be switched to the next lead group automatically and start to record the ECG signal of the next lead group. Before the recording of the ECG signal, 1mV calibration will be conducted automatically and marked on the record paper.
2. Manual Printing Mode : Under the manual working mode, the user can select the lead group to record the ECG according to the need. When the user needs to record the ECG signal of another lead group, it needs to be switched manually. Under the manual working mode, the user can select the “Channel Mode” according to the need and set the record parameters or other parameters according to different channel modes.
3. Rhythm mode : Under the rhythm mode, the user can select the rhythm lead according to the need and record the rhythm waveform of the lead.  Channel format :3×4+1R, 3×4+3R, 6×2+1R.“3×4+1R” means that the mode of the lead waveform display on the screen is 3 lines and 4 columns and a rhythm lead.
