EKG Rhythm Interpretation - Compact & Portable Reference Card – Rapid Interpretation Guide – Dual Horizontal & Vertical Layout

Informative, definitely tiny print, probably best for someone rather better acquainted with cardiac background who just needs a quick reference.

Yes, it is small, but they tell you that before you buy it. It does fit well in carry bag with Kardia mobile device, so small is good. I am old with not great eyes, but I can read it when I need to.

This reference card is very compact, which makes it convenient to carry as a badge buddy. However, the text and rhythm strips are extremely small—if you don’t have excellent eyesight or a magnifying glass, it’s hard to read and identify the rhythms clearly. While it’s marketed as a quick interpretation guide, I found myself spending more time trying to distinguish the waves than actually interpreting them. For basic portability, it’s fine, but if you’re looking for a more practical tool for rapid rhythm recognition, this card falls short.

The quality of the product is very good. It appears to be intended for attaching to the back of an ID tag, which would be convenient for medical professionals. The only drawback I see is that because of this the card is quite small and may be difficult for some to read.

These EKG charts are the best. They show all the common readings, and what they mean, even for A-Fib and other disorders. This is the chart to get if you have no medical training like me. Large cards and easy to read. I'm very happy with it, and the low price is an added bonus.
