R-CAT for Arrhythmias EKG Pocket Reference Guide Plus EKG Badge – Great Study Card for ECG Interpretation - ACLS and PALS Training – Cardiac Rhythm Interpretation Made Easy

Useful, worth your money, good quality, easy to use and very flexible.

This is a must have for any medical student studying the heart. Not only does it show you the pattern but also the timing. Very worth the price.

This is a replacement. I either lost or someone accidentally took it. Great information with good pictures.

This little tool for monitor techs or those learning ekg is amazing. Unfortunately the book my trainer gave me to study was SO confusing...but this little guide has helped me more than the book. I would recommend this 100% if your having trouble comprehending the different rhythms. You won't regret it!

Exactly what I needed!

This is a great tool while going through cardiology

Very sturdy and easy to take with you

I teach EKG interpretation and I am impressed with this tool. It's sturdy, laminated, easy to read and covers many things. Examples of rhythms, arrhythmias and even ST depression, elevation and Q wave formation. Excellent tool for someone starting off.
