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.
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 example of an ECG showing a slurred upstroke of QRS complex which is best appreciated in the precordial leads and a PR interval of less than 120 ms.
Shown below is an example of an ECG demonstrating a delta wave in lead V2 along with left axis deviation.
