EKG examples
Shown below is an EKG depicting delta waves in V1, V2, and aVF, coupled with short PR interval suggestive of WPW syndrome.
Shown below is an EKG depicting delta waves (slurred up-stroking QRS complex) in precordial leads, aVL, and aVF, wide QRS complexes, short PR interval and left axis deviation suggesting WPW syndrome. There is an rsr1 pattern in the chest lead V1.
Shown below is an EKG of Wolff-Parkinson-White syndrome (antero-lateral pathway) depicting delta waves in leads V3, V4, V5, and V6, wide QRS complexes (>110 ms) and short PR interval.
Shown below is an EKG of type B Wolff-Parkinson-White syndrome depicting delta waves in leads I, aVL and V2-V6 and short PR interval.
Shown below is an electrocardiogram of Wolff-Parkinson-White syndrome (antero-septal pathway) depicting wide QRS complex and delta wave in II, III and aVF.
Shown below is an electrocardiogram of Wolff-Parkinson-White syndrome (antero-septal pathway).
Shown below is an electrocardiogram of Wolff-Parkinson-White syndrome (epicardial pathway) depicting delta wave in precordial leads.
Shown below is an electrocardiogram of Wolff-Parkinson-White syndrome (left posterior pathway) depicting in delta wave in V5 and V6.
Shown below is an electrocardiogram of Wolff-Parkinson-White syndrome (Posteroseptal pathway) depicting a delta wave in leads II and precordial leads.
Shown below is an EKG showing abnormal QRS form with delta waves seen best in the precordial leads and shortening of PR interval signifying aberrant conduction pathway.

Shown below is a 12 lead electrocardiogram of WPW syndrome type II.
WPW syndrome with an orthodromic circus movement tachycardia: Narrow complex tachycardia with a rate of 200 bpm (RR interval 320 ms). After 5 cycles, the tachycardia suddenly stops and four multiform complexes are seen without any P waves. These complexes should be regarded as a polymorphic ventricular tachycardia, which is not uncommon after an adenosine-terminated supraventricular tachycardia. A 5th complex is preceded by a P wave. The subsequent 4 complexes show a widened QRS complex and all are immediately preceded by a P wave. The initial phase of the QRS complex is slurred and positive in all available leads. Sinus rhythm continues thereafter with gradual abbreviation of the QRS complex until a 120 msec wide QRS complex remains.
The same patient's EKG during sinus rhythm. A discrete delta wave is clearly visible. The morphology of the delta wave suggests a left posterior Kent bundle. center|800px
The recording below shows sinus rhythm. The remarkable finding is the short PR interval (<120 ms) and the slurred upstroke of the QRS. This is best seen in leads I and aVL, V2 to V6. Of interest is that the delta wave is negative in the inferior leads and gives the false impression of an inferior wall myocardial infarction. This tracing show WPW ventricular pre-excitation.
Shown below is an EKG demonstrating WPW syndrome. The accessory pathway is located in the left posteroseptal region.
Shown below is an EKG depicting an atrial flutter in a patient with WPW syndrome. There is 1:1 conduction down a bypass tract.
