A patient recovering from an acute myocardial infarction has a heart rate of 30 beats per minute. Which area of the heart should the nurse consider as pacing this patient's heart rate?
The nurse calculates a patient's QRS interval as being 0.08 seconds. What should the nurse do for this patient?
Nothing since this is a normal finding.
