Recording of Brugada electrocardiogram pattern by an implantable cardiac monitor.

A 51-year-old man with Brugada syndrome (BrS) electrocardiogram (ECG) type I pattern underwent implantable cardiac monitor (ICM) insertion. After pre-insertion potential mapping, we could observe the patient-specific repolarization abnormalities on the subcutaneous ECG provided by the ICM. A few weeks later, we received remotely a device recording with a higher ST-segment elevation and a longer duration of the interval between the onset of the coved elevation and its termination at the isoelectric line. Our observation supports the conceptual premise that ICM could add information on quantifying the amount of time with abnormal ECG patterns rather than only for the diagnosis of cardiac arrhythmias.
