HORLALA ECG 7 Step Ruler, ECG 7 Step Ruler for ECG/EKG Interpretation, ECG Ruler, Follow a 7 Step Plan, Transparent EKG Calipers Measuring Tool, Portable ECG Assessment Tool EKG Card(1 PC)

With a follow Follow a 7 Step Plan with reference points along the way for those hard to remember key points! 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 comes in handy when identifying the area of a myocardial infarction. Remember: V1-V4= Anteroseptal MI & V3V6= Anterolateral MI
