Our Story

Innovation Born from Clinical Need

Where emergency medicine expertise meets cardiac monitoring innovation

At C-Booth Innovations, innovation meets expertise. Our roots lie in San Diego, where a team of dedicated Emergency Physicians embarked on a mission to transform cardiac care.

We are not just a medical device company; we are innovators and caregivers committed to one crucial goal: to revolutionize the diagnostic quality and consistency of ECG performance. This commitment drives us towards one outcome — ensuring the right intervention is delivered at the right time, for every patient.

Our breakthrough: a state-of-the-art wearable ECG portfolio line designed for continuous 12-lead monitoring, with the capability to expand up to 18-lead for improved STEMI detection. Our technology is crafted to seamlessly integrate across the continuum of care, from prehospital to acute care settings.

Our Mission

Our Values

The Principles That Guide Our Innovation

Every cardiac monitoring solution we develop is rooted in these core values shaping how we serve emergency medicine and critical care

Clinical Excellence

Every design decision is driven by clinical need. We collaborate directly with emergency physicians, paramedics, cardiologists, and EPs to ensure our technology delivers superior diagnostic accuracy when it matters most.

Patient-Centered Innovation

Patient outcomes drive our innovation. We're committed to ensuring the right intervention is delivered at the right time, improving care quality across the continuum.

Speed & Precision

In cardiac care, seconds matter. Our EXG™ platform deploys in under 60 seconds with AHA-compliant electrode placement, delivering rapid, accurate 12-lead monitoring.

Regulatory Integrity

We maintain the highest standards of quality and compliance. Our commitment to regulatory excellence ensures clinicians can trust our technology in critical care settings.

Clinical Partnership

We're not just suppliers—we're partners. From implementation to ongoing support, we work alongside healthcare teams to optimize cardiac monitoring workflows.

Continuous Improvement

Innovation never stops. We leverage real-world clinical feedback to refine our technology, staying ahead of emerging needs in emergency and acute cardiac care.

Experience Our Values in Action
