Overview of Wolff-Parkinson-White (WPW) Syndrome • WPW Syndrome refers to the presence of a congenital accessory pathway (AP) and episodes of tachyarrhythmias. The term is often used interchangeablely with pre-excitation syndrome • First described in 1930 by • Incidence is 0.1 – 3.0 per 1000 • Associated with a small risk of sudden cardiac death • PR interval 110ms • Discordant ST-segment and T-wave changes (i.e. in the opposite direction to the major component of the QRS complex) • Pseudo-infarction pattern in up to 70% of patients — due to negatively deflected delta waves in inferior/anterior leads (“pseudo-Q waves”), or prominent R waves in V1-3 (mimicking posterior infarction) • Aberrant conduction via an AP leads to early ventricular depolarisation (pre-excitation), which manifests as a short PR interval and slurred upstroke of the QRS complex • Conduction still occurs via the AV node, and is actually a brake on AP conduction, ceasing its propagation path in the ventricle • QRS duration is thus prolonged, but not to the same extent as in bundle branch block • Because there is an initial abnormal direction of depolarisation (e.g. originating from left ventricle in left-sided AP), there will be an abnormal direction of repolarisation. This produces appropriately discordant ST segment and T wave changes (see above diagram) Pathophysiology of pre-excitation and APs Pre-excitation refers to early activation of the ventricles due to impulses bypassing the AV node via an AP...

QTc intervals are pathological if greater than 460 ms in children under the age of 15, 450 ms in men, and 470 ms in women. Short QTc Interval Diagnostic criteria for Short QT syndrome are not entirely defined because it is a new clinical entity, described in 2000. A QTc interval less than 340 ms is usually accepted as pathological. More Information: We hope we have been able to help you. For further details on How to determine the Electrical Axis, click

PR Interval The PR interval is the time from the onset of the P wave to the start of the QRS complex. It reflects conduction through the AV node. • The normal PR interval is between 120 – 200 ms (0.12-0.20s) in duration (three to five small squares). • If the PR interval is > 200 ms, • PR interval < 120 ms suggests AV nodal (junctional) rhythm. • Second degree heart block, Mobitz type I (Wenckebach phenomenon). • Note how the baseline PR interval is prolonged, and then further prolongs with each successive beat, until a QRS complex is dropped. • The PR interval before the dropped beat is the longest (340ms), while the PR interval after the dropped beat is the shortest (280ms). Pre-excitation syndromes • • These involve the presence of an accessory pathway connecting the atria and ventricles. • The accessory pathway conducts impulses faster than normal, producing a short PR interval. • The accessory pathway also acts as an anatomical • Patients present with episodes of paroxsymal supraventricular tachycardia (SVT), specifically atrioventricular re-entry tachycardia (AVRT), and characteristic features on the resting 12-lead ECG. AV nodal (junctional) rhythm • Junctional rhythms are narrow complex, regular rhythms arising from the AV node. • P waves are either absent or abnormal (e.g. inverted) with a short PR interval (=retrograde P waves). • ECG: Accelerated junctional rhythm demonstrating inverted P waves with a short PR interval (retrograde P waves)

A Normal ECG Reading An An electrocardiogram is an image of electrical conduction in the heart. By examining normal changes on the electrocardiogram, clinicians can identify various cardiac processes. But what is a normal ECG reading? In this article, we’ll be discussing the things you need to know about reading an ECG and identifying a normal ECG. Why is an ECG reading important? An electrocardiogram(ECG or EKG) is often used along with other tests An ECG can help How to identify a normal ECG? How to identify a normal ECG? • Wave Positive or negative deflection relative to the baseline, indicating a specific electrical event. The waves on an ECG include P waves, Q waves, R waves, S waves, T waves, and U waves. T waves are usually rounded and asymmetrical, rising more slowly than falling, and Isolated T-wave inversion in asymptomatic adults is usually a normal variant. • Interval The time between two specific ECG events. Intervals commonly measured on an ECG include the PR interval, the QRS interval (also called the QRS duration), the QT interval, and the RR interval. Intervals are usually between 0.12 and 0.20 seconds. The duration of a QT interval is usually less than or equal to 0.40 seconds for men and less than or equal to 0.44 seconds for women. • Segment The length between two specific points on the ECG should be the baseline amplitude (not negative nor positive). The segments on the ECG include PR, ST, and TP segments. Segments in any lead typically do not depress ...
