From time to time, cardiac monitors will report an incorrect heart rate, too low or too high, due to inappropriate interpretation of pacing artifacts. Clinicians faced with this issue should first palpate the pulse and correlate with a pulse oximeter plethysmogram to verify the findings on a cardiac monitor. New monitors have settings to adapt for patients with pacemakers and provide more accurate heart rates.
