Therefore, the criteria for diagnosing LAE on a 12-lead ECG is as follows: The length of the P wave in lead II is greater than 120 milliseconds OR The downward deflection of the P wave in lead V1 ...

A 76-year-old woman presents with a persistently rapid heart rate that she attributes to her pacemaker. What does the ECG ...

Because the atrial rate is so fast, and the action potentials produced are of such low amplitude, P waves will not be seen on the ECG in patients with atrial fibrillation. At times, the P wave ...

Multiple other ECG traits have also emerged as potential predictors of stroke, namely cardiac electrical/structural remodeling – Q wave, QRS/QT duration, bundle blocks, P wave duration/amplitude ...
