Rhythm Management

Boston Scientific CHARISMA™ X4 CRT-D

The CHARISMA X4 device is equipped with SmartCRT™ technology, which allows physicians to individualize pacing strategy in terms of “where, when, and how.”
EnduraLife™ battery technology provides long service life — approximately up to 13.3 years with MultiSite Pacing activated, and even longer when deactivated.
The device is ImageReady™ MR-conditional, meaning full-body MRI examinations (1.5T and 3T) can be performed without restrictions.
The X4 portfolio includes three-dimensional spiral electrode leads, enabling basal positioning and making it suitable for patients with high thresholds or phrenic nerve stimulation (PNS) issues.
MultiSite Pacing mode offers 216 vector combinations and helps optimize therapy through automated recommendations.
The device is compact (32.5 cm³) and slim (9.9 mm), improving patient comfort.

The CHARISMA EL device is equipped with EnduraLife™ battery technology, providing an estimated longevity of approximately 17.5 years (VR models) and 16.0 years (DR models).
Its compact size (29.5 cm³) and slim profile (9.9 mm) are designed to enhance patient comfort.
ImageReady™ MR-conditional design allows patients to undergo full-body MRI scans (1.5T and 3T) without restrictions.
The Atrial Arrhythmia Report feature monitors AT/AF status and helps evaluate the effectiveness of AF therapy.
PaceSafe™ automatic threshold management (for RV, RA, LV) automatically adjusts pacing output to ensure a safe margin.
AcuShock™ technology, along with advanced rhythm discriminators and sensing filters, helps prevent inappropriate or unnecessary defibrillation shocks.

The EMBLEM MRI S-ICD device is fully subcutaneous, meaning no leads are placed inside the heart or blood vessels.
It is ImageReady™ MR-conditional and allows MRI scans under specific conditions (1.5T).
The SMART Pass filter reduces cardiac oversensing, thereby minimizing inappropriate shocks.
The device includes AF Monitor functionality, which detects and reports atrial fibrillation even in silent or asymptomatic cases.
Battery life is approximately 8.7 years based on real-world data.
The EMBLEM MRI S-ICD uses INSIGHT™ technology, which analyzes overall rhythm patterns rather than individual beats to support predictive therapy decisions.
