### How do you interpret an EKG paper?

EKG Interpretation 1 Heart rate: The standard paper speed is 25 mm (5 large squares)/sec. … 2 Rhythm: The cardiac myocytes have an inherent automaticity and can generate an electric impulse. … 3 Axis: Determine both P wave and QRS axes. … 4 Durations/Intervals: a) P wave: Represents atrial depolarization. … More items…

### What do the squares on the ECG paper mean?

On the standard ECG paper, with standard calibration, the squares represent: The standard calibration signal will look like this: This will be present at the beginning or end of all four rows of the trace, and shows: Alterations to calibration can be made for a number of reasons.

### What is the standard paper speed of EKG?

Basic EKG interpretation 1. Heart rate: The standard paper speed is 25 mm (5 large squares)/sec. This means that if the interval between two beats (R-R) is 5 large squares, the HR is 60 beat/min.
