Further Inpatient Care

Admit patients for testing and pacemaker placement when indicated.

Next

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:

Previous
Next

Transfer

Transfer patients for complicated dysrhythmias and pacemaker implant.

Previous
Next

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).
