ECG changes in potassium disorders 🟢 HYPERKALEMIA (Elevated Serum K⁺) EKG changes evolve predictably with rising potassium levels: → Early (K⁺ ~6-7 mmol/L): Prolonged PR interval, Flattened P waves. → Moderate (K⁺ ~7-8 mmol/L): Tall, peaked ("tented") T waves. → Severe (K⁺ ~8-9 mmol/L): Prolonged QRS duration, ST-segment depressions. → Critical (K⁺ >9 mmol/L): Sine wave pattern, culminating in ventricular fibrillation or asystole. ⚫️ HYPOKALEMIA (Low Serum K⁺) Presents with a distinct pattern o

⚡Visual Atlas of ECG Waves & Conduction Pathways: ⚡️ P Wave: Atrial depolarization (contraction) — the initial upward deflection. ⏱ PR Segment: Post-P wave isoelectric line; denotes AV nodal conduction delay. 💥 QRS Complex: Ventricular depolarization — Q (initial ↓), R (prominent ↑), S (↓ post-R). 🚨 ST Segment: Post-QRS isoelectric phase; elevation/depression = critical pathology (e.g., ischemia/MI). 🌀 T Wave: Ventricular repolarization — gentle upward curve. #Cardiology #Electrophysiology #E

#Hypokalemia 📌Hypokalemia on ECG 🫀 ➡️Low potassium delays cardiac repolarization. ECG changes progress as levels fall: 3.5 -5.5 mEq/L: Normal baseline. 3.0 mEq/L: Flattened T-wave; U-wave appears. 2.0 mEq/L: Prominent U-wave; prolonged PR interval. 1.0 mEq/L: Critical. ST-depression and giant U-waves; high arrhythmia risk #ECG #nurses #doctor #medical | House of Medical Skills and Knowledge with Dr IsraelGi

Potassium changes show up early on the ECG especially in the T wave. I think of it like a landscape: ⛰️ High potassium → climbing the mountain → peaked T waves 🌿 Low potassium → down in the valley → flat T waves, ST depression, U waves Simple visual. Easy recall. Perfect for ECG exams and real-world recognition. Learn. Adapt. Respond. | The Medical Lounge

Characteristic ECG Findings in Hypertrophic Cardiomyopathy (HCM) 📈ECG is a screening tool. Findings necessitate echocardiography (or CMR) for definitive diagnosis, phenotyping, obstruction assessment, and risk stratification. 🔹 LVH: Elevated QRS amplitude in limb/precordial leads, signaling increased myocardial mass. 🔹 Q Waves: Deep, narrow Qs in II, III, aVF, I, aVL, V5-V6, mimicking MI due to septal hypertrophy. 🔹 ST-T Changes: Depression & T-wave inversion in lateral leads, hinting at rep
