What Are the Features to Look for Before Buying an ECG Machine?

There are different types of electrocardiography (ECG) machines on the market that provide various features – everything from the standard hand-held devices to machines with many more features used in hospitals. Regardless of size and capabilities, they all work in a similar manner to discover abnormalities in heart activity.

Some of the features to look for when purchasing an ECG machine include:

Number of Channels

Does the ECG operate with multiple channels? Also, does it have a minimum of three channels providing simultaneous data from the ECG? Does the ECG obtain all 12 standard leads at the same time? In the best scenario, the ECG unit should have the ability to print a minimum of three leads of the ECG waveform on a continuous basis, with switching manually between leads.

Keyboard for Entering Patient Demographics

Printing the patient’s demographics on the ECG printout can make it look more professional, which is a beneficial feature in terms of presentation.

ECG Print Size

Print sizes vary based on the ECG machine. Some print 8×11 sheets of paper. Others print strips of half-size sheets or 60 mm rolls of ECG paper. The former are preferable for handling and storage.

Computer Connectivity

If the ECG has computer connectivity, is the output compatible with the most available ECG and EMR management systems? Some machines are only compatible with the pricey ECG management systems the manufacturer provides.

Screen for Viewing ECG Before Printing

A screen for view the ECG prior to printing ensures a stable baseline before the ECG is performed.

Battery Capacity and Charging Time

An ECG machine should charge up to maximum quickly – in seconds. If the unit is not intentionally charged, it should disarm automatically within two minutes. An ECG should be able to operate in battery power, including interpretation and reporting of results with no interruption when power has been disconnected.

PC Based ECG Machine

Some PC-based ECG machines provide all of the above features and can also provide various other benefits. These include the ability to connect to electronic medical records, print on regularly copy paper, search a database of ECGs performed, and incorporate other diagnostic tools, such as Holter monitoring, spirometry, vital signs monitoring, and stress testing. With a PC-based ECG machine, you can view all 12 leads in real time.
