Instructions for Chapter 7 Worksheets

For each arrhythmia, examine the whole strip. Determine an atrial and ventricular rate. In the figure below, the atrial rate in indeterminate. The ventricular rate is irregularly irregular and consistent with atrial fibrillation. The correct way to calculate the heart rate in atrial fibrillation is to count the number of QRS complexes in a random six second sample and then multiply that number by ten to get the ventricular rate in beats per minute (bpm). The figure below shows 4 QRS complexes in a six-second interval. Four multiplied by 10 would yield a ventricular rate of 40 bpm.

Clinical Associations:

Hyperthyroidism, pulmonary embolism, COPD, hypertension, valvular heart disease, CHF.

Worksheet 7.1

For each arrhythmia, examine the whole strip. Determine an atrial and ventricular rate.

Atrial rate Ventricular rate Diagnosis

Atrial flutter. Three second pause demonstrates atrial flutter waves, but no QRS complexes.
