Electrocardiogram (ECG): Definition & Wave Types

Overview of the ECG Waves, Deflections, Intervals, Durations –

🚨 Hyperkalemia : ECG Essentials 🚨 ✔️ HyperK: Peaked T → Sine wave → Cardiac arrest. Watch how increasing potassium levels affect the heart. As K rises, notice these ECG changes: Flattened P Wave: Impaired atrial depolarization. Widened QRS Complex: Delayed ventricular depolarization. These changes can lead to severe arrhythmias and potentially cardiac arrest if not treated promptly. #Hyperkalemia #Cardiology #ECG #MedicalEducation #CardiacArrest #Healthcare👇🏻 Save 📌 | Share 🔗 | Tag a colle

Abdallah Othman on Instagram: "Narrow QRS Tachycardias: A Visual Guide 🫀 A narrow QRS complex tachycardia (<120 ms) originates above the ventricles. Systematic ECG analysis is key to an accurate diagnosis. 1. Assess Ventricular Regularity A) Regular R-R Intervals: 1. Atrial Flutter: Sawtooth flutter waves (II, III, aVF); atrial rate ~300 bpm. 2. AVNRT: Most common paroxysmal SVT. P waves often buried in QRS. 3. Orthodromic AVRT: Retrograde P wave post-QRS → Short RP Tachycardia. 4. Sinus Tachyc
