After 100 years, the 12-lead electrocardiogram (ECG ... the lead axis perpendicular to the ST-segment vector, and then find the most positive or most negative ST-segment deviation to determine ...

We calculated metrics using 6-minute sliding windows over ECG data starting from treatment onset/offset and moving bi-directionally with a 3-minute step. To correct daily and between-subject variation ...

Several classical ECG changes could, however, not be ascribed to specific mechanisms ... This seems to be a paradox but may be ascribed to axis deviation reducing anterior QRS forces (Sokolow-Lyon) as ...

ECG Challenge: What's Causing This Long Pause? An older woman visits the hospital after fainting, and telemetry shows long pauses in her heart's rhythms. What does the ECG show?

After localization of the ablation site, RF ablation was performed at 30 W. If a sudden change in morphology, axis, and duration of the surface ECG (QS in V1, R in V6, widening of the QRS complex, and ...

we classified patients into three groups based on their AI-estimated ECG age: those who were ≥6 years older than the CA, those who were within 6 years of the CA, and those who were ≤6 years younger ...
