When interpreting a telemetry strip, which is the first question to determine?

• A. Is it Regular? (R-R)
• B. P waves present?
• C. QRS width
• D. What is the Rate? (atrial, ventricular)

Answer: (D)

Determining the rate first sets the stage for interpreting the strip. Knowing whether the heart is tachycardic, bradycardic, or in a normal rate immediately guides what you expect to see and how aggressively to interpret the rest. To find the rate, you estimate how many beats occur per minute by counting R-R intervals (or using the 6-second method if the rhythm is irregular). Once the rate is known, you then assess regularity, P waves, and QRS width to classify the rhythm more precisely and identify underlying conduction or atrial/ventricular origin issues. Without establishing rate first, the subsequent analysis can be misleading because the rate influences how those other features present and what they imply for patient status.
