Evaluation of the Efficacy and Safety of Wearable ECG (AT-Patch) in Patients With Hypertrophic Cardiomyopathy Requiring 48-Hour Holter MonitoringEvaluation of the Efficacy and Safety of Wearable ECG (AT-Patch) in Patients With Hypertrophic Cardiomyopathy Requiring 48-Hour Holter Monitoring

* Validation of validity, superiority, and safety of data analysis results using AT-Patch compared to 48-hour Holter test results * Number of subjects: 100 (including 10% dropout rate) * Performance and safety were verified by simultaneously attaching a 48-hour Holter and a wearable Holter device (ATP-C75 or ATP-C135).
