Shown below is an EKG showing abnormal QRS form with delta waves seen best in the V leads.

• 

  The upstroke of the QRS-complex is 'slurred', resulting in a delta-wave (arrow).

• 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 Δ wave is clearly visible. The morphology of the Δ wave suggests a left posterior Kent bundle.
