🫀 ST-Elevation ≠ STEMI always! 🚨

Convex + merges into T = STEMI ❤️
Coved + inverted T = Brugada 💜
Concave + tall T (ST/T 0.25) = Pericarditis 💙

بعض أساتذتنا وكتير من الزملاء طلبوا مني العودة للفيس
والحقيقة مكنتش حابب أرجع له تاني نهائي
لا طب ولا غيره بعد ما تم إغلاق جميع صفحاتي من الفيس بدون أي إبداء أسباب منهم
لكن لعله خير
عموماً بعيداً عن أي تفاصيل تانية
دي صفحة طبية عامة عملتها بحيث تكون مركزة على الجانب العلمي فقط ..
وربنا ييسر كل خير للجميع
والحمد لله كنا مستمرين في طريقنا على جروبات التليجرام
يعني مش واقفين على منصة واحدة سواء فيس أو غيرها

يعني الحمد لله جروبات التليجرام شغالين عليها باستمرار من فضل ربنا علينا
فمتشغلش بالك بالفيس كتير 😇

🫀 Atrial Fibrillation | Recognizing the ECG Signature

AF is the most common sustained cardiac arrhythmia. On ECG, look for two hallmarks: absence of organized P waves, replaced by fibrillatory activity, and a characteristically irregularly irregular ventricular rhythm due to variable AV nodal conduction.

Loss of coordinated atrial contraction eliminates the “atrial kick” and may impair ventricular filling.

🎯 ECG pearl: No organized P waves + irregularly irregular R–R intervals = think AF.
