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.
