WebFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size. WebThe inverted (negative) T-wave. T-wave inversion means that the T-wave is negative. By definition, the T-wave is negative if the terminal portion of the T-wave is below the baseline. T-wave inversions are actually graded …

WebOne of the more frequent dilemmas in ECG interpretation is the differential diagnosis of an rSr' pattern in leads V1 -V2 . We often face this finding in asymptomatic and otherwise healthy individuals and the causes may vary from benign nonpathological variants to severe or life-threatening heart diseases, such as Brugada syndrome or arrhythmogenic right … WebAbstract. Background: T-wave inversions (TWI) can signify serious pathology, but may also represent a benign variant. One such variant has been termed the "persistent juvenile" T-wave pattern (PJTWP). It is characterized by TWI in the right precordium, and has been understood to represent an arrested stage of the normal electrocardiographic ...
Web5. ST segment elevation is a normal finding on the ECG of young men. In recent years, it has been realised that ST elevation is present on the ECG of the majority of normal young men. This ‘male pattern ST elevation’ is usually observed in the right sided chest leads and is no cause for concern. The ECG under consideration is a nice example.
