Real-time, non-invasive mapping to find where dangerous heart rhythms start
Development of an automatic real-time personalized non-invasive localization of the site of origin of the earliest ventricular activation
A computerized tool that uses your standard 12-lead ECG to quickly and automatically locate where ventricular arrhythmias begin to help people with recurrent dangerous heart rhythms.

What this research studies
This project builds a computer method that analyzes routine 12-lead ECGs in real time to pinpoint the origin of ventricular tachycardia (VT) or premature ventricular complexes (PVCs). The team will train and test the algorithm using patient ECGs and sites confirmed by invasive mapping or prior treatments. They will compare the automatic localizations to expert readings and to the known ablation or radiotherapy targets. The end goal is a patient-specific, non-invasive map that helps doctors focus mapping and treatment more quickly during procedures.
Who could benefit from this research
Good fit: People with recurrent ventricular tachycardia or frequent PVCs who are being considered for catheter ablation or noninvasive treatment options.
Not a fit: People without ventricular arrhythmias or those whose arrhythmia source cannot be seen on a surface 12-lead ECG are unlikely to benefit from this approach.
Why it matters
Potential benefit: If successful, the tool could speed up procedures and help doctors target ablation or noninvasive radiotherapy more precisely, potentially lowering recurrence rates and procedure times.
How similar studies have performed: Related ECG- and body-surface mapping approaches have shown promise, but a fully automatic, real-time, patient-specific localization tool is still relatively new.
