πŸ’“βš‘ Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) – The Stress-Triggered Heart Storm

1️⃣ What is CPVT?

β€’ A genetic disorder of the heart’s calcium channels 🧬 – the cells that control the heartbeat can’t handle calcium properly.
β€’ Leads to calcium overload inside heart cells πŸ’₯ (similar to what happens in digoxin toxicity).
β€’ The heart is structurally normal, but electrically unstable.

2️⃣ When does it strike?

β€’ Triggered by stress, either physical exercise πŸƒβ€β™‚οΈ or emotional excitement 😱.
β€’ Catecholamines (adrenaline & noradrenaline) are the triggers ⚑.
β€’ At rest, the heart often behaves normally πŸ›Œ.

3️⃣ What happens in the heart?

β€’ Calcium overload causes early afterdepolarizations, which are abnormal extra beats leading to dangerous rhythms.
β€’ On ECG: bidirectional VT (classic) or polymorphic VT.
β€’ Can cause fainting, palpitations, or sudden cardiac arrest.

4️⃣ Who is affected?

β€’ Mostly children and young adults
