Delta Wave

Delta Wave Overview

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.

The characteristic ECG findings in Wolff-Parkinson-White syndrome are:

Short PR interval (< 120ms)
Broad QRS (> 100ms)
A slurred upstroke to the QRS complex (the delta wave)

ECG Interpretation: Tachyarrhythmias

Part four of a 5 part lecture series on ECG/EKG Interpretation on tachyarrhythmias with Dr Theo Sklavos and cardiologist A/Prof William Wang. This lecture series is aimed primarily at medical/nursing/paramedicine students and junior trainees, but will hopefully be useful as a refresher course for the more experienced.

Tachyarrhythmia

Identify the common types of tachycardia. Split into wide vs narrow complex.
