Conditions

Cardiomyopathies, Pacemaker, Artificial

Brief summary

The purpose of this study is to collect a saliva sample from patients with a pacemaker to study genes involved in cardiomyopathy, a condition where the heart muscle is abnormal.

Detailed description

DNA will be extracted from the saliva to test for changes in genes related to cardiomyopathy.
