Welcome to our Wolff Parkinson White Syndrome reference page.
This page provides a definition followed by an synopsis of EKG features.
Links to our practice drills, quizzes, lessons and interactive guides can be found below.
Definition of Wolff-Parkinson-White Syndrome
Wolff Parkinson White Syndrome can occur when there extra electrical pathway between the atria ventricles.
This causes tachycardia. Wolf Parkinson White syndrome can occur at any age but is usually diagnosed in younger patients.
- Chest pain or tightness
- Shortness of breath
Wolff Parkinson White Syndrome Electrophysiology
The second pathway that is present with Wolff Parkinson White Syndrome does not slow the electrical impulse as does the AV node.
Wolff Parkinson White Syndrome Rhythm Strip
The following table summarizes the key features of the Wolff Parkinson White Syndrome EKG rhythm strip.
|Rhythm||Regular unless atrial fibrillation present
|Rate||Normal (60-100 bpm)
|PR Interval||Can be short (<0.12 sec)
|QRS||Usually wide (> 0.12 sec)
|Notes||Look for short PR interval and/or delta wave
A delta wave (positive or negative) distorts the early part of the QRS complex
A good starting point for learning EKG interpretation is our EKG Basics training course. The course provides training on the key features of an EKG tracing. These features include observing P-wave forms, measurement of EKG intervals and segments, assessment of rhythm, calculating heart rate, and the evaluation of other relevant wave segments. The arrhythmia practice drills allow students to build skills interactively.
EKG Practice Drills
The heart arrhythmia practice drills provide a test EKG tracing and users are asked to identify the type of arrhythmia. Many of these drills include tachycardia EKG tracings. Each answer is immediately evaluated and the correct classification of the EKG tracing is provided, along with a detailed explanation. A directory of arrhythmias is also provided.
Arrhythmia Practice Drills
The quiz is structured like a classroom exam. The quiz present twenty EKGs. Users answer each question and at the end of the quiz, a fully graded report is provided. This graded report provides scoring as well as the correct answer to each question. Top scores and mean scores are also provided. This quiz draws its questions from a library of over 300 EKGs, allowing users to take the quiz multiple times.
ECG Monitor Challenge (beta version)
Try the beta version of our ECG monitor challenge. This quiz uses a simulated patient monitor with moving waveform instead of a paper tracing. As with the quiz described above, twenty questions are presented, then a graded report is available.
