📌Clinical Guide: Torsades de Pointes (TdP) & Long QT Syndrome (LQTS) --- Key Causes 1. Drug-Induced QTc Prolongation: - High-risk agents: Amiodarone, fluoroquinolones, macrolides, SSRIs, antipsychotics, antiemetics. 2. Electrolyte Imbalances: Hypokalemia, hypomagnesemia. 3. Inherited LQTS: LQTS1/2/3 mutations (confirm via genetic testing). Diagnosis - ECG: QTc ≥460 ms (women) / ≥450 ms (men). - Indeterminate Cases: Holter monitor, exercise stress testing. Acute TdP Management 1. Immediate Actio

ACLS Cardiac Arrest Algorithm:Shockable vs. Non-Shockable Rhythm Pathway · Shockable: VF/VT. Treat with immediate defibrillation. · Torsades de Pointes is a polymorphic VT. Defibrillate if pulseless. Correct underlying causes (e.g., hypomagnesemia, long QT). · Non-Shockable: PEA/Asystole. Treat with CPR, Epinephrine, and reversible causes (Hs & Ts). Cycle: 2 min CPR → Rhythm Check → Act. #TorsadesDePointes #PolymorphicVT #CardiacArrest #ACLS #ECG #VF #VT #PEA #Asystole #Resuscitation #Cardiology

Hypomagnesemia (⬇️ magnesium) can be caused by issues such as alcoholism, malnutrition, malabsorption, hypoparathyroidism, hypocalcemia, and diarrhea. One of the most important signs to look out for is the cardiac rhythm pictured here: Torsades de pointes. This arrhythmia is a type of rapid heart rate (tachycardia) that starts in the ventricles and can quickly become 🚨 life-threatening 🚨 if not treated promptly! ✨NCLEX® TIP✨ Initial treatment for this arrhythmia = magnesium via IV push!
