[Sinoatrial node disease in cardiac amyloidosis. Description of 2 cases].
We describe two patients with probable amyloid infiltrative cardiomyopathy and episodes of syncope. A sick sinus syndrome was suspected by Holter monitoring in both patients. The diagnosis was supported by the finding of a marked prolongation of sinus node recovery time in one case. In both patients a permanent pacemaker was implanted which prevented recurrence of syncopal episodes.
