STEP 1: DETERMINE IF THE RHYTHM IRREGULAR OR IRREGULAR Find the first cardiac complex in the ECG and locate the “QRS” complex. Identify the “R” waves throughout the remainder of the ECG strip. You can make small markers above each complex for ease of identification. Next you will take telemetry calipers to trace the “R to R” intervals from the first two cardiac complexes through the remainder of the ECG strip. Some variance is to be expected but if the variance in the tracing is greater than .12 seconds or greater than 3 small squares then that rhythm is considered to be irregular.
