AI vs MD ECG-Reading for Cath Lab Activation (This Week in Cardiology, by Dr. John Mandrola)
In this episode of This Week in Cardiology, Dr. John Mandrola reviews a study comparing physicians with PMcardio’s Queen of Hearts™ AI. The results show the AI achieved 89% accuracy in detecting subtle STEMI equivalents—far surpassing doctors’ 66%—highlighting its potential to transform early heart attack triage.
About the Podcast
This Week in Cardiology is hosted by Dr. John Mandrola, a practicing cardiologist, writer, and educator known for his sharp commentary on clinical studies and cardiovascular care. The podcast highlights recent research and real-world cases that shape modern cardiology practice.
Summary of the Episode
In this episode, Dr. Mandrola reviews a study comparing physicians to PMcardio’s Queen of Hearts™ AI ECG model for identifying STEMI equivalents and mimics in critical ECGs. Conducted in San Antonio across community hospitals and EDs, the study presented 18 complex ECG cases to emergency physicians, cardiologists, and the AI.
- Results: Physicians (both EM doctors and cardiologists) achieved ~66% accuracy, while the AI reached 89% accuracy in determining when to activate the cath lab.
- The AI outperformed clinicians, particularly in subtle cases like de Winter pattern, transient STEMI, hyperacute T-waves, and bundle branch block presentations.
- Dr. Mandrola emphasized that while no one misses obvious STEMIs, it’s the subtle cases where AI can make a life-saving difference.
“No one misses the 3–4 mm tombstone ST elevations. It’s the subtle STEMI mimics that are tough. If you’re a patient with an occluded artery but not a conclusive ECG, you hope either for luck, a master ECG reader, or a really good AI algorithm.”

About PMcardio
PMcardio is a CE-marked Class IIb AI medical device that interprets any 12-lead ECG — from a photo or a digital file — in seconds. It detects 50+ ECG findings, including occlusion myocardial infarction (OMI) — the acute coronary occlusions that conventional STEMI criteria miss in over half of cases. Its Queen of Hearts™ OMI model holds FDA Breakthrough Device Designation, and PMcardio is already used by 100,000+ clinicians who have analyzed more than 2.5 million ECGs.
About Powerful Medical
Powerful Medical is a medical-technology company using artificial intelligence to transform how cardiovascular disease — the world’s leading cause of death — is diagnosed. Founded in 2017, it built PMcardio, the world’s first AI medical device to detect acute coronary occlusion (OMI) from an ECG. Its research is published in the European Heart Journal – Digital Health and validated across 25+ clinical studies, and its Queen of Hearts™ model earned FDA Breakthrough Device Designation. To date, PMcardio has supported the detection of 120,000+ heart attacks across 150+ hospital deployments worldwide.
