Practice Question
The nurse is measuring the client's ECG strip. What is the approximate ventricular rate noted on the six-second strip?
Answer Choices:
Correct Answer:
80 beats per minute
Rationale:
💠A 6-second ECG strip is used for quick rate estimation — each strip equals 30 large boxes (since paper runs at 25 mm/sec).
💠To calculate the heart rate, the nurse counts the number of QRS complexes within that 6-second interval and multiplies by 10 to approximate beats per minute.
💠In the provided strip, there are 8 QRS complexes in 6 seconds.
💠Thus, 8 complexes×10=80 beats per minute.
💠This rhythm shows a normal sinus rhythm, as both rate (60–100 bpm) and regularity appear normal, indicating stable cardiac conduction.
