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

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.

The graph was a little small

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.

I'm a retired cardiac ICU NURSE so this information is very useful to me. I'm not sure how useful it is to those that are not used to reading heart rhythms and knowing the significance of what they mean. I know what needs immediate follow up.

WAY too small to read. highly disappointed. Nice information but just not readable, Yes it is credit card sized and would fit in wallet - if you have good eyes then this is ok.

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.

I had 3 Panic attacks one for each week. I mimicked a a heart attack so i thought. and I talked with my BFF who is in Nursing and she told me that she had one a year ago and was not a Heart attack. and i have not had one since. It was good to know. It is better to have and not need / than to need and not have.

I bought this for my brother because he has problems. It works very well so he is always in touch with his doctor.
