ECG Cases

🟡 Case 34 🟡 👇👇👇👇

Sinus rhythm with left atrial abnormality. Most striking are tall right precordial R waves with pathologic inferior and lateral Q waves giving a "reverse" type R wave progression. There are also ST-T abnormalities in I, aVL, V6. Thus the patient has coronary artery disease (CAD), s/p large infero-(p…

64-year-old man with increasing pedal edema. What is the ECG diagnosis?

🟡 Case 33 🟡 👇👇👇👇

The ECG shows sinus tachycardia with an indeterminate (not "indeterminant") axis and prominent T wave inversions in V1-V4 with delayed precordial transition zone (R=S in V6). QT is at upper normal limits and there is an S wave in lead I with a minuscule R in III, aVF. P waves are peaked (well, almos…

39-year-old man with acute dyspnea and "muscle strain" in left leg.

🟡 Case 32 🟡 👇👇👇👇

Be careful here. This may look superficially like sinus but if you look in V1, you can see P waves just before the QRS (there is right bundle branch block (RBBB) and also P waves in the T wave (halfway in between) which are partly hidden. Atrial rate is about 150, ventricular rate 75. This is an atr…
