EKG / ECG Machines

12-lead electrocardiography is standard these days. Our clinical customers use it to manage things like infarction, ischaemia, arrhythmia, and implantable devices. We have a wide range of machines, from very basic to quite sophisticated. Increasing computational power and better signal processing is opening new options for analysis relevant to all fields of cardiology. For detecting myocardial ischaemia and infarction, coming improvements will include QRS morphology feature analysis, analysis of high frequency QRS components, and techniques that involve vectorcardiography and digital imaging. For spotting arrhythmias, there will be better P-wave analysis. For risk stratification and patient-selection for medical device therapy, there will shortly be new markers like automated QRS-score for scar quantification, the QRS-T angle, and the T-wave peak-to-end-interval.

Get in touch, and we’ll talk through your particular needs.  There’s a machine, new or reconditioned, that’s right for you. We stock all the brands, like GE, Marquette, HP, ACS, Burdick, Medgraphics, and Ivy.  

EKG / ECG Machines Questions & Answers

That depends entirely on what you want from your data. 250 – 500 Hz can work perfectly well in clinic. 1000 Hz is better, and it’s what’s in use these days, generally. More than this won’t necessarily add information for the classical assessment methods.
Keep an eye on robustness to noise, wavelet parameter choice, and simple things, like good electrode contact, good amplifers, and good filters. Some algorithms are better than others, too.
Yes. A 'pacemaker detection' feature is common. It uses specialized software that infers the presence of a pacemaker by band-pass filtering and an analog comparator circuit. It works as long as the machine has a high analog-to-digital conversion rate. That conversion rate is more important than sampling rate.
Some people don’t like them, and much has been written about this. Computers can get things wrong, mostly because people’s trace patterns, and their medical histories, can vary quite a lot. Computer diagnoses can also distract clinicians from doing careful readings themselves.
One’s German, and one’s English. They mean the same thing.
