Delta Wave • LITFL Medical Blog • ECG Library Basics
WEBFeb 10, 2022 · The Delta wave is a slurred upstroke in the QRS complex. It relates to pre-excitation of the ventricles, and therefore often causes an associated shortening of the PR interval. It is most commonly associated with pre-excitation syndromes such as WPW.
Wolff–Parkinson–White syndrome - Wikipedia
WEBA characteristic delta wave (above the blue bar), a short PR interval (red bar) of 80 ms, and a long QRS complex (blue bar plus green bar) at 120 ms are visible. WPW is commonly diagnosed on the basis of the electrocardiogram in an asymptomatic individual.
Wolff-Parkinson-White Syndrome - Part 1 - ECG Medical Training
WEBJun 29, 2015 · In WPW pattern Type B the delta waves are predominantly negative in leads V1-V3 and predominantly positive in leads V4-V6. It can be mistaken for left bundle branch block or left ventricular hypertrophy with strain.
Wolff-Parkinson-White (WPW) Syndrome - Medbullets
WEBDec 7, 2021 · ventricular pre-excitation results from an aberrant conduction tract from the atria to the ventricle, known as the bundle of Kent. this fast accessory tract bypasses the slowest-conducting AV node. ventricles then depolarize earlier than normal. this causes the classic delta wave and widened QRS.
Asymptomatic Ventricular Preexcitation (Wolff-Parkinson-White …
WEBFeb 17, 2022 · Wolff-Parkinson-White (WPW) syndrome affects 0.1-0.3% of the general population. 1 The characteristic electrocardiogram (ECG) features are (i) shortened PR interval (<120 ms), (ii) slurred QRS upstroke (delta wave), and (iii) prolonged QRS duration (>120 ms) (Figure 1A).
Patient education: Wolff-Parkinson-White syndrome (Beyond ... - UpToDate
WEBMay 15, 2024 · Conduction through the accessory pathway produces a characteristic ECG pattern. A classic finding is a short PR interval (the time for conduction between atria and ventricles) and a delta wave, which reflects early conduction (preexcitation) to the ventricles through the accessory pathway.
Wolff-Parkinson-White Syndrome - StatPearls - NCBI Bookshelf
WEBAug 7, 2023 · 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.
