With continuous innovation for patient comfort, the next generation LifeVest WCD garment marks the third advancement of the LifeVest system over the last five years. Patients rate the newest LifeVest® garment as more comfortable and easier to use.¹

• Lightweight,  breathable fabrics, designed for performance 
• Flat seams, designed to be comfortable against the skin
• Soft, double-plush straps
• The most inclusive range of garment sizes from 26"–56"

20+ years of LifeVest design enhancements have led to a median real-world Wear Time® of 23.4+ hours/day.^2-4 

LifeVest® ranks #1 in patient compliance this decade at 23.4+ hours/day (median) based on peer-reviewed publications and real-world data.^2-4  

When early SCD risk is high, the modern LifeVest WCD delivers incomparable safety, as shown across nearly 20,000 patients in SCD-PROTECT (2025).²

• 0.5% inappropriate shock rate – the lowest reported in contemporary WCD literature
• 99.7% of patients experienced no skin irritation requiring discontinuation
• 0 deaths from VT/VF in the largest real-world study of LifeVest patients

SCD-PROTECT, which featured a modern version of the LifeVest WCD, confirms the urgent need for SCD protection in both NICM and MI/CAD populations. Early SCD risk remained high, even with widespread use of GDMT.² A recent study of >20,000 patients presented at AHA 2025 confirm these findings.⁵

When early SCD risk is high, trust the proven efficacy of LifeVest

• 97% first shock success rate^6-9
• >96% one-year survival¹⁰
• 100% VT/VF conversion in an RCT¹¹

1 in 14 patients experience an actionable arrhythmia during LifeVest use.⁶ Developed with machine learning, LifeVest ECG Classifier filters out noise and identifies arrhythmias that may require intervention — from ablation to ICD implant.

See how ECGs captured by LifeVest enabled physicians to modify their patient’s treatment path.

The LifeVest Patient App helps patients get the most out of their LifeVest experience.

• Track progress with access to their own Wear Time^® and Activity data.
• On-demand device education, success stories, and support resources – all at your patients’ fingertips.
