What does the EKG show?
+ EKG Interpretation
Dr. Ohlbaum's Explanation
This EKG was done on a 75 year old man who presented with episodes of facial numbness. His MRI showed multiple small, age indeterminant ischemic strokes. His initial EKG was normal sinus rhythm and he had a RBBB but look carefully at what happens on this one.
The first 2 beats have P waves, those are 2 SINUS beats. But then there is an early beat which may be a PAC and the rest of the ekg is afib (some areas may be aflutter, look at V1). We caught him going from sinus to afib (or fib flutter).
