Designed with the scientific 7-step ECG interpretation method, it provides clear, intuitive reference points for those hard to remember key points with a step-by-step follow-through process Features: Crafted in an ID-sized, transparent format Fits seamlessly into badge holders, pockets, or toolkits Perfect for on-the-go use in workplaces, classrooms, or clinical settings Resistant to wear, waterproof, and easy to clean Maintaining its clarity and functionality over long-term use in demanding environments Allows you to measure the heart rate, and see if the PR interval, QRS complex, QT intervals are out of the normal range and ST elevation/ depression, The EKG ruler will be an excellent addition to your ID badge Suitable not only for healthcare professionals but also for anyone wanting to master ECG interpretation. With a follow Follow a 7 Step Plan with reference: 1.Heart rate- This will provide a quick but approximate heart rate. 2.Rhythm- Assess whether the heart rate is regular or irregular 3.Axis- A quick reference for normal, left or right axis deviation. The arrows pointing up indicate a positive deflection & arrows pointing down indicate a negative deflection. 4.PR interval- This gives you a reference of the PRI range in milliseconds. Also to the right side, are blocks you can measure the PRI. 5.QRS interval- As above this gives you the range of the QRS & QTc in milliseconds and again you can measure the QRS interval with the blocks. 6.ST elevation/ depression- Place the straight back line along the isoelectric line to assess if there is either ST elevation or depression also there is a ruler so you can measure the degree of either in millimetres. 7.T wave- Lastly, a quick reference for potential T wave abnormalities. Plus top right references the leads view of the heart which
