The diagnosis is sinus rhythm with interpolated premature ventricular complexes, in a trigeminal pattern, with retrograde concealed conduction. The rhythm is irregular, but there is a repeating ...

2. Short PR interval and delta waves consistent with Wolff-Parkinson-White (WPW) syndrome Explanation: Wolff-Parkinson-White syndrome occurs when a person is born with an "accessory pathway" that can ...

The diagnosis is normal sinus rhythm, WPW pattern, PACs in bigeminal pattern, and pseudo inferior wall infarction. The rhythm is irregular and there is a pattern of group beating (ie, two QRS ...

The time from the beginning of the P wave, indicating atrial depolarization, to the beginning of the QRS complex, representing ventricular depolarization, is the PR interval. This represents the time ...
