The purpose of this research study is to understand more about various heart rhythms (electrical problems) in persons with hypertrophic cardiomyopathy with and without sleep apnea.
Adult patients with hypertrophic cardiomyopathy and without known atrial fibrillation or pacemaker/implantable cardiac defibrillation will undergo implantable loop recorder implantation. No direct interventions will be performed. Prospective observation of atrial and ventricular arrhythmia incidence and burden will be assessed, with additional analyses performed based on the presence or absence of obstructive sleep apnea.

Atrial fibrillation incidence in hypertrophic cardiomyopathy
Define the incidence ratio of newly diagnosed atrial fibrillation in hypertrophic cardiomyopathy, with and without sleep apnea
Time frame: Final incidence to be calculated at study conclusion, after 3 years of rhythm monitoring.
Atrial fibrillation recurrence in hypertrophic cardiomyopathy
Determine the frequency of recurrent atrial fibrillation in hypertrophic cardiomyopathy, with and without sleep apnea
Time frame: Final recurrence rate to be calculated at study conclusion, after 3 years of rhythm monitoring.
Ventricular arrhythmia incidence in hypertrophic cardiomyopathy
Define the incidence ratio of newly diagnosed ventricular arrhythmias in hypertrophic cardiomyopathy, with and without sleep apnea
Time frame: Final incidence to be calculated at study conclusion, after 3 years of rhythm monitoring.
