Genetic Basis of Pacing-induced Cardiomyopathy

Genetic Basis of Pacing-Induced Cardiomyopathy

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.

Study Overview

• Status: Completed
• Conditions: Cardiomyopathies; Pacemaker, Artificial
• Intervention / Treatment: Other: Saliva sample

Detailed Description

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