AI-Augmented ECG Interpretation Using Smartphone Technology (Mayo Clinic Cardiovascular CME Podcast, by Dr. Anthony Kashou)
In this Mayo Clinic Cardiovascular CME episode, Dr. Robert Herman explains how PMcardio, an AI-powered smartphone medical device, is transforming ECG interpretation. Validated on thousands of ECGs and across clinical trials, PMcardio enables any clinician to achieve cardiologist-level diagnostic accuracy, improving arrhythmia and acute MI detection while streamlining care decisions.
About the Podcast
The Mayo Clinic Cardiovascular CME Podcast delivers expert-led discussions on cutting-edge advances in electrocardiography. Hosted by Dr. Anthony H. Kashou, it provides practical education on the latest diagnostic tools, technologies, and best practices in cardiovascular care.
Summary of the Episode
In this episode, Dr. Kashou welcomes Dr. Robert Herman, Chief Medical Officer and co-founder of Powerful Medical, to discuss the development and validation of PMcardio, a web- and smartphone-based AI medical device for ECG interpretation.
- AI-powered digitization pipeline: Converts any ECG image — regardless of format, quality, or manufacturer — into a fully digital waveform ready for AI analysis.
- Current challenges in ECG interpretation: Lack of standardization, noise sensitivity in non-AI algorithms, limited datasets, and insufficient integration of patient context.
- PMcardio validation: Tested on over 12,000 ECGs and benchmarked against general practitioners and cardiologists. Results showed superiority over non-specialists and non-inferiority to cardiologists.
- Clinical impact: In a randomized controlled trial across 58 primary care centers with >800 patients, PMcardio improved arrhythmia detection fivefold and enhanced acute MI detection while supporting appropriate referral decisions.
- Future directions: Moving beyond subjective labels toward outcome-based training, predictive risk modeling, raw ECG data analysis, and expanding applications to heart failure, electrophysiology, and sudden cardiac death.
“In validation, PMcardio consistently outperformed non-specialists and matched the accuracy of cardiologists across all major diagnoses.”— Dr. Robert Herman, Mayo Clinic Cardiovascular CME

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.
