Atrial fibrillation and other atrial tachyarrhythmias in hypertrophic cardiomyopathy

INTRODUCTION

Hypertrophic cardiomyopathy (HCM) is a genetically determined heart muscle disease most often (60 to 70 percent) caused by mutations in one of several sarcomere genes which encode components of the contractile apparatus. (See "Genetics of hypertrophic cardiomyopathy".)

HCM is characterized by left ventricular hypertrophy of various morphologies, with a wide array clinical manifestations and hemodynamic abnormalities (figure 1) . Depending in part upon the site and extent of cardiac hypertrophy, HCM patients can develop one or more of the following abnormalities:

These structural and functional abnormalities can produce a variety of symptoms, including:

  • Fatigue
  • Dyspnea
  • Chest pain
  • Palpitations
  • Presyncope or syncope
