Further Inpatient Care
Admit patients for testing and pacemaker placement when indicated.
Further Outpatient Care
Asymptomatic patients with SND should be observed for symptoms.
In patients with a pacemaker, the following should be performed on routine pacemaker interrogations:
- Monitor leads and battery status.
- Ensure adequate heart rate support at rest, during daily activities, and exercise.
- Monitor for pacemaker malfunction, such as pacemaker-mediated tachycardia.
- Ensure minimal right ventricular pacing.
- Monitor for atrial fibrillation and atrial flutter events.
Transfer
Transfer patients for complicated dysrhythmias and pacemaker implant.
Deterrence/Prevention
Treat heart diseases related to SND and extrinsic causes to delay and prevent SND.
Complications
- Sudden cardiac death (rare)
- Syncope
- Fall
- Thromboembolic events including stroke (especially in patients with tachy-brady syndrome)
- Congestive heart failure
- Arrhythmias
Prognosis
The incidence of sudden cardiac death in patients with SND is very low[8] . The mortality in patients with SND is primarily determined by underlying heart diseases. The patients with tachy-brady syndrome have a worse prognosis than patients with isolated SND. Pacemaker therapy does not appear to affect survival in patients with SND[5, 6, 7] and is, therefore, used primarily for alleviation of symptoms.
Patient Education
- Educate patients to recognize symptoms of SND.
- Educate patients on pacemakers.
- Family members should learn cardiopulmonary resuscitation (CPR).
