Master the Concept in 90 Seconds: Prof. John (Nanomedicine & Cancer Researcher) deconstructs the Ventricular Repolarization mechanisms that define T-wave polarity. Stop memorizing and start decoding the Transmural Gradient Logic. ⚡

🎯 Core Physiological Mechanisms Covered:
✨ Epicardial-Endocardial Recovery: Why the T-wave is concordant due to the "First-In, Last-Out" action potential duration. 📉
✨ Vector Physics: Understanding why repolarization moving away from a lead creates a positive deflection. 📐
✨ Action Potential Dispersion: The biophysical science of Phase 3 differences and their role in diagnostic precision. 🔬

✝️ Closing Oblation
United in the Tridentine spirit and the coronation echoes of Charlemagne, this channel serves the global community—from Medical Students mastering the USMLE to seekers of the Counter-Revolution through the harmony of Faith and Science in its highest form.
May the Logos, the Word Made Flesh, guide every seeker toward the Social Kingship of Christ. All academic training, from basic medical research to the clinical exploitation of physiological mechanisms, is laid down as a lowly oblation before the throne of Almighty God, under the patronage of the Holy Martyrs who shed their blood for the Truth. 📿

“Illum oportet crescere, me autem minui.” — He must increase, but I must decrease. (John 3:30)

Acknowledging that apart from Him we can do nothing, the presenter considers himself but an unworthy servant—the least of all, and as one born out of due time—striving only to be a faithful steward of the mysteries of God.

Christus Vincit, Christus Regnat, Christus Imperat. ✠
