The J point is the the junction between the termination of the QRS complex and the beginning of the ST segment. EKG J-point
QT interval is the time from the start of the Q wave to the end of the T wave, time taken for ventricular depolarisation and repolarisation
ECG PR segment is the flat, usually isoelectric segment between end of the P wave and the start of the QRS complex.
Assessment / interpretation of the EKG PR interval. ECG PR interval is the time from the onset of the P wave to the start of the QRS complex.
The characteristic ECG findings in the Wolff-Parkinson-White syndrome include a slurred upstroke to the QRS complex (the Delta 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.
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 morphology and interpretation. A Q wave is any negative deflection that precedes an R wave. LITFL ECG Library
Overview of normal P wave features, as well as characteristic abnormalities including atrial enlargement and ectopic atrial rhythms
ECG exam template with headings and prompts which can be used as template for ECG-based exam questions, such as the FACEM FRCEM OSCE
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
Worked examples of the three main methods to calculate ECG rate, along with an explanation of paper speeds and relevant clinical applications
