Advancing Cardiac Monitoring for More Accurate and Effective Arrhythmia Diagnosis

Extended Holter monitoring for cardiologists, clinics and IPS: up to 7 days of continuous ECG recorded while your patients go about their daily lives, with every study reviewed by cardiologists.

Why Extended Monitoring

Making Arrhythmia Diagnosis Accessible to All

Intermittent arrhythmias often don’t show up in a short recording, and patients can wait weeks for a standard Holter. Harmony Holter gives you longer, more comfortable monitoring and a clear report — without adding workload to your team.

Our Service

From recording to report

Cardiologist-Reviewed Reports

Every recording is interpreted by cardiologists and delivered to the referring physician as a clear, actionable report.
