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
