After writing this review, I got my hands on the full version. So this review continues here.

Studying ECG can be one hell of a mountain to climb, especially when you’re at the novice level of cardiac education. Due to how vital it is, it’s imperative that you can not only make the distinction between Mobitz II AV Block and sinus arrhythmia, but also understand the intricacies of the cardiac conduction behind them, and all of the other rhythm abnormalities. Learning these things like the back of your hand is one thing, but combining all that knowledge is, at times, overwhelming. So after 12 months of scouring the internet, trying to find a decent cardiac anatomy and 12-lead ECG simulation tool, I was over the moon to stumble upon Epicardio Simulation; a cardiac electrophysiology tutorial application, developed by Epicardio ltd.
The program is available in 3 main forms; Epicardio ECG, ECG and Pacing, and 3-day trial. As I don’t have £149 kicking around (the price of the basic ECGcentric offering), I can’t review the full version and all of its features, but the 3 day trial version (which is £0), is well within my price range. Thus, I shall only be commenting on the features with which I have been able to sample.
Thankfully, the collection of features available to trial version users is still extensive, so I have lots to cover, and perhaps I’ll spring for the full version when funds allow. The question is: does the trial impress enough to warrant the large expense? Let’s investigate further:
Almost as soon as you open Epicardio, the vibrant display hits you; a large, anatomically accurate heart fills most of the screen as colourful depolarisation waves travel across the atria, and down through the ventricles. The live single lead ECG tracks with concordance, and the right hand menu buttons are nicely presented and clearly display exactly what they do.
Depolarisation mechanics can be viewed through the heart as a whole, or each section on its own. Atria, ventricles, bundle branches and coronaries, can all be viewed independently whilst depolarisation occurs, so it’s possible to learn how the various components of the cardiac system operate during each cycle.
Further structural overlays can be added, in the form of the vena cava, thoracic cage and a translucent torso, further adding to the ability to understand the heart’s positioning in humans.
The electrical readout on the lower region of the screen comes with the option of cycling through all 12 leads on the standard ECG, individually, but as well the real time single lead ECG, users can also activate a live 12-lead, which again updates in real time with each cardiac cycle. This mode itself allows for different viewing styles, including the layout presented on most standard ECG printouts, which is perfect for students. It also features all the subtle morphology differences and minor, unavoidable muscle tremors that one would find on a real ECG recording. Calipers are a welcome feature, too, and they work well in Epicardio, allowing for measurements that students will definitely have to become proficient in throughout training.
Further customisation options are numerous; the colours of the depolarisation waves are changeable, as is the colour of the backdrop. Rather than simply offering pre-set rhythms, Epicardio allows you to manually alter heart rate, and, possibly more importantly, AV delay, so it’s possible to visibly alter the depolarisation wave on the beating heart in the centre of the screen, and see the live trace display a prolonged PR interval.
A most welcome feature is the electrode view option. A click on this button brings up a moving image of the heart within the thorax, and the standard precordial electrode sites. These electrodes can be moved anywhere and the real-time result displayed on the recorded trace, so it’s rather nice to be able to explore the difference in the voltage/time graph that occurs with electrode misplacement.
A defibrillator option allows you to shock the heart, although this was of limited use to me, as I did not have access to the fibrillatory rhythms that come with the paid version, but the artificial pacemaker below it allows the user to alter pacing pulses and observe the changes on the ECG.
My issues with Epicardio range from those that exist simply because the version I tried is restricted, to those that are nought but minor niggles, so I shall focus on those minor niggles, as oppose to content I simply have not paid to access.
The ECG trace, whilst being incredibly customisable, would feel much more authentic if it were set against a proportional image of standard ECG paper; being able to view the trace against the background most students will see throughout studies would be a great primer in the early days of study, and considering the trace speed is adjustable, I was disappointed it wasn’t a feature.
The option buttons look lovely, offer genuine function and, once you’ve been through the tutorial and played around with them, make perfect sense. It would perhaps be helpful if a brief explanation appeared when the mouse pointer was placed over each one, however, as it was a struggle remembering what the more vague options actually did, especially for the first few hours of using the program.
However, as I stated, these are only minor gripes. Epicardio is a wonderful and genuinely fun bit of software to use. I’ve got a feel for how beneficial having this in the beginning of my studies would have been. The layout, options, functionality and simplicity of using Epicardio are all near-perfect, so I can’t wait to get a hold of the full version, complete with pacemaker-specific options. If you have a spare weekend, then follow the link at the top of the page, and download the free trial. If you have a spare £149/£215, then follow the same link and download the full version, as if it’s provides even 50% more features than the demo, I can be certain it’s worth it.
I will review the full version as soon as I can.
