Detection of Ventricular Tachycardia by an Implantable Cardiac Monitor 8 Months Post-myocardial Infarction.

Following a non-ST-elevation myocardial infarction (MI), a 68-year-old hypertensive, severely obese woman with 45% left ventricular ejection fraction underwent an implantable cardiac monitor (ICM) insertion. After 8 months, the ICM remotely transmitted multiple non-sustained ventricular tachycardia episodes. Symptomatic during these events, the patient underwent an invasive electrophysiologic stimulation, which induced ventricular arrhythmia.

Remote monitoring of implantable cardiac monitors in patients with unexplained syncope: Predictors of false-positive alert episodes.

Background: Remote monitoring is recommended for patients with implantable cardiac monitors (ICMs), but compared to other cardiac implantable devices, ICMs are less accurate and transmit a higher number of alerts.

Objective: The aim of this study was to investigate the predictors of false-positive (FP) arrhythmic alerts in patients with unexplained syncope who were implanted with ICM and followed by an automatic remote monitoring system.

Methods: We retrospectively evaluated all consecutive patients who received a long-sensing vector ICM for unexplained syncope between January 2019 to September 2021 at our Syncope Unit.

Remote monitoring of implantable loop recorders reduces time to diagnosis in patients with unexplained syncope: a multicenter propensity score-matched study.

Background: There are little data on remote monitoring (RM) of implantable loop recorders (ILRs) in patients with unexplained syncope and whether it confers enhanced diagnostic power.

Objective: To evaluate the effect of RM in ILR recipients for unexplained syncope for early detection of clinically relevant arrhythmias by comparison with a historical cohort with no RM.

Methods: SyncRM is a propensity score (PS)-matched study prospectively including 133 consecutive patients with unexplained syncope and ILR followed up by RM (RM-ON group).

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.

Remote assessment of QT interval: A new perspective for implantable cardiac monitors.

Background: There is an unmet need for simple tools for monitoring QT intervals. The feasibility of measuring the QT interval on the single‑lead subcutaneous electrocardiogram (subECG) recorded and transmitted by implantable cardiac monitors (ICMs) has never been tested.

Methods: We performed a standard ECG in patients who had already been implanted with a long sensing vector ICM (BIOMONITOR, Biotronik SE&Co.
