Key Treatment Considerations<br />

• Sinus bradycardia in the absence of key symptoms requires no specific treatment (monitor / observe)<br />

• Fluid bolus may address hypotension and lessen need for pacing or treatment with atropine<br />

• Sedation prior to starting pacing is not required. Patients with urgent need should be paced first.<br />

• The objective of sedation in pacing is to decrease discomfort, not to decrease level of consciousness.<br />

Patients who are in need of pacing are unstable and sedation should be done with great caution<br />

• Monitor respiratory status closely and support ventilation as needed<br />

• Atropine is not effective for bradycardia in heart-transplant patients (no vagus nerve innervation in<br />

these patients)<br />

• Patients with wide-QRS second- and third-degree blocks will not have a response to atropine because<br />

these heart rates are not based on vagal tone. An increase in ventricular arrhythmias may occur.
