Diagnostic Considerations

Other conditions to be considered in patients with suspected sudden cardiac death (SCD) include arrhythmogenic right ventricular (RV) dysplasia and Brugada syndrome.

Important considerations include the following:

  • Recognize and initiate early management of patients with ischemic heart disease. The importance of this cannot be overestimated, because approximately 80% of SCD cases can be attributed to ischemic heart disease.

  • Use appropriate medical therapy for ischemic heart disease (eg, beta-blockers).

  • It is very important to involve a specialist in cardiovascular disease in the care of patients who have had a cardiac arrest or have symptoms of ischemic heart disease, valvular disorders, or presentations with complex arrhythmias.

  • It is very important to educate patients about the consequences of noncompliance with medical therapy.
