@dr.ahmad_nabeel: ๐ซ T WAVE ON ECG โ QUICK GUIDE The T wave represents ventricular repolarization. ๐ Normal T wave โข Usually upright in I, II, V3โV6 โข Normally inverted in aVR โข Usually < 5 mm in limb leads โข Usually < 10 mm in precordial leads โข Smooth, asymmetric appearance โ ๏ธ Important T-wave abnormalities ๐บ Tall/peaked T waves โ Hyperkalemia โ Early STEMI (โhyperacuteโ T waves) ๐ป T-wave inversion โ Myocardial ischemia โ NSTEMI/unstable angina โ Ventricular strain โ CNS disorders โ Normal variant in some leads โฌ๏ธ Flattened T waves โ Hypokalemia โ Ischemia โ Nonspecific changes ๐ก Exam pearl: Hyperkalemia โ tall, narrow, peaked T waves Hypokalemia โ flattened T waves + prominent U waves ๐ง Remember: T = Ventricular Repolarization #ECG #drahmadnabeel #TWaves #Cardiology #MedicalEducation
