2024年10月8日 · Dominant R wave in V1 suggests a left-sided AP, and is sometimes referred to as “Type A” WPW; Tall R waves and inverted T waves in V1-3 mimicking right ventricular hypertrophy (RVH) — these changes are due to WPW and do not indicate underlying RVH

2015年6月29日 · Wolff-Parkinson-White (WPW) Syndrome. Described in 1930 by Wolff, Parkinson, and White as an ECG pattern found in young, otherwise healthy adults who experienced bouts of atrial fibrillation and atrial tachycardia; In 1932 Holzmann and Scherf proposed that the syndrome was due to an accessory pathway between the atria and ventricles

2022年2月4日 · Symptomatic ECG AV re-entrant tachycardia or AF AVRT: the re-entry impulse usually travels down the AV node and back up the accessory pathway (delta wave not present), occasionally the re-entry impulse may pass down the accessory pathway and up the AV node (wide QRS tachycardia + delta wave)

2023年8月7日 · The hallmark electrocardiographic (ECG) finding of WPW pattern or preexcitation consists of a short PR interval and prolonged QRS with an initial slurring upstroke (“delta” wave) in the presence of sinus rhythm.

2022年2月17日 · In the absence of a documented tachyarrhythmia or related symptoms, the ECG findings alone are referred to as WPW pattern. The chief fear of both WPW syndrome and pattern is the risk for sudden cardiac death (SCD) – presumed to result from rapid VPE precipitating ventricular fibrillation (VF).

2022年1月26日 · Electrocardiogram (ECG) Key features of WPW on an ECG in sinus rhythm include: Short PR interval <120ms; Delta wave: slurred upstroke of the QRS; Widened QRS complex >110ms; Incongruous ST segment and T waves changes; Prominent R waves in V1-3: this mimics a posterior infarction

Discover WPW Syndrome, including delta waves, EKG features, and Kent's bundle localization. Learn about Type A (left) and Type B (right) WPW pathways. ECG book.com

Although the ECG and an electrophysiology study are diagnostic, the characteristic features are not always seen on ECG. Treat like paroxysmal SVT. Treat like ventricular tachycardia. WPW with AFIB. ↑ Burns E. Wolff-Parkinson-White Syndromes. Life in the Fast Lane. http://lifeinthefastlane.com/ecg-library/pre-excitation-syndromes/.

ECG examples of pre-excitation (short PR interval, prolonged QRS duration, delta waves, secondary ST-T abnormalities). Click to zoom. Individuals with accessory pathways are at risk of developing atrioventricular reentrant tachycardia (AVRT).

2024年8月21日 · Three features must be present on the electrocardiogram (ECG) when a patient is in normal sinus rhythm to diagnose the Wolff-Parkinson-White syndrome. An estimated 1 in 2,000 people have an accessory pathway, most of whom will …
