An ECG records the electrical activity of the heart. Most routine tests in clinics are resting ECGs: the patient lies still, electrodes are attached, and the machine records a short trace. A doctor then reads it.

What “12 channel” actually means

A standard ECG looks at the heart from twelve angles, called leads. A 3-channel machine shows three of them at a time and works through the rest. A 12 channel ECG machine shows and records all twelve together. That gives a doctor the complete picture on one printout and usually makes the test quicker.

What you see on the machine

• A colour LCD display that shows the live trace, so you can check that the electrodes are making good contact before you record. A digital ECG machine with LCD display saves a lot of repeat tests.
• A keypad with numbered lead keys, plus mode, speed and filter buttons and a start/stop key.
• Indicator lights for power, charging and battery.
• A paper compartment on the left for the printout.

Who it suits

It works as a resting ECG machine for clinics, physician’s rooms, diagnostic labs, nursing homes and hospital OPDs. Many cardiologists keep one in the consulting room, and many hospitals use one in the ward as well. If your work needs continuous heart monitoring or exercise testing, this is the wrong machine, because it records short resting traces only.

Before you buy any ECG machine

Ask the seller these things. They matter more than the channel count.

• Brand and model. Is it a known brand? Who does the service?
• Warranty. How long, and what does it cover?
• Accessories. Does it come with the patient cable, electrodes, paper and power cable?
• Battery. How many hours of use and how many recordings per charge?
• Paper. Which size of thermal paper does it take, and where can you buy it?
• Interpretation. Does it only record, or does it also give automatic measurements? Either way, the doctor makes the final reading.
• Regulatory papers. Ask to see the licence or registration documents.

Anyone comparing the 12 lead ECG machine price in India will find a wide range, from around ₹45,000 for budget units to over ₹1.5 lakh for well-known international brands. The price usually follows the brand, the service network and the software, not the number of channels.

Looking after it

Wipe the body and screen with a soft damp cloth. Do not use strong solvents on the screen. Clean the patient cable gently and do not bend it sharply, because cable damage is the most common cause

of noisy traces. Keep spare paper and electrodes on hand. If the machine has a battery, charge it fully now and then even if it stays plugged in most of the time.
