Delighted to share a concise update on the latest NEJM review of Long QT Syndrome 🫀📘 — a masterful synthesis by Schwartz & Crotti that reframes how we recognize risk, personalize therapy, and prevent sudden death in this genetically mediated disorder. The piece highlights ion-channel biology, gene-specific triggers, the impact of modifier genes, and the effectiveness of a tiered therapeutic approach including beta-blockers, mexiletine, and left cardiac sympathetic denervation ⚡️🧬🛡️.   For clinicians and trainees, it's a compelling reminder that precise diagnosis, careful QT interpretation, and yearly risk reassessment remain central to saving lives. Highly recommended reading for anyone involved in cardiac electrophysiology or inherited arrhythmia care 📚✨
