This ECG was kindly donated to the ECG Guru website by Dr. Ahmed for open discussion among our members. The patient was a 70+ year-old man who presented with a complaint of dizziness. His serum potassium level was found to be 6.5 (normal is 3.5 - 5.0). Upon correction of his K levels, his rhythm was atrial fibrillation at 130 / min.
WHAT DO YOU THINK ABOUT THIS INITIAL ECG? What is causing the slow rate? Is there atrial activity? Do you see QRS morphology changes? What about the anterior ST and T wave changes?
We look forward to hearing from our members! And thanks to Dr. Ahmed for donating this interesting ECG.
