Built for the Fight.
Trained for the Heart.
Cardiac collapse can strike without warning, even among the best. At SRT Heart Doc, we’re building a tactical cardiology movement to train, equip, and protect those who serve under pressure.
What is Tactical Cardiology?
Tactical Cardiology is a new standard of cardiovascular readiness built specifically for first responders, law enforcement, military personnel, firefighters, and tactical medics.
It’s more than clinical theory — it’s a movement to prevent senseless cardiac-related deaths in the field through early detection, specialized training, mission-adapted protocols, and medically sound tools that work under pressure.
Whether you’re kicking in doors, fighting fires, or running toward gunfire, your heart should be just as ready as your gear.
