Figure 2: Suggested algorithm for genetic testing in AF
Legend: Stepwise approach to diagnosis and management of genetic AF. In addition to traditional one-time or ambulatory electrocardiogram and transthoracic echocardiogram, patients with newly diagnosed AF should have a detailed family history of AF (including time of onset), sudden cardiac death, and ICD taken. Patients with significant personal or family history should undergo genetic testing, and, if positive, be referred for further counseling by a cardiologist specializing in genetics.
