Delta Wave
The characteristic ECG findings in the Wolff-Parkinson-White syndrome include a slurred upstroke to the QRS complex (the Delta wave)

U Wave
The U wave is a small (0.5 mm) deflection immediately following the T wave, usually in the same direction as the T wave. Best seen leads V2 and V3.
R wave
On this page we will discuss and provide examples of R wave abnormalities such as Dominant R wave in V1, aVr and PRWP LITFL ECG Library
Q Wave
Q Wave morphology and interpretation. A Q wave is any negative deflection that precedes an R wave. LITFL ECG Library
P wave
Overview of normal P wave features, as well as characteristic abnormalities including atrial enlargement and ectopic atrial rhythms
ECG Exam Template
ECG exam template with headings and prompts which can be used as template for ECG-based exam questions, such as the FACEM FRCEM OSCE
ECG Rhythm Evaluation
Guide to ECG rhythm analysis. The rhythm is best analysed by looking at a rhythm strip. This is a 7 step approach to ECG rhythm analysis
High Lateral STEMI
ST elevation primarily localised to leads I and aVL, usually associated with reciprocal ST depression and T wave inversion in inferior leads
Brugada Syndrome
Brugada Syndrome - ECG abnormality with a high incidence of sudden death in patients with structurally normal hearts. Brugada - EKG Library
What is Brugada Syndrome?
Brugada Syndrome is an ECG abnormality (Brugada sign) in association with specific clinical findings
ECG Rate Interpretation
Worked examples of the three main methods to calculate ECG rate, along with an explanation of paper speeds and relevant clinical applications
Ashman Phenomenon
Ashman phenomenon (1947) aberrant ventricular conduction, usually of RBBB morphology, which follows a short RR interval and preceeded by a relatively prolonged RR interval.
