網頁2024年4月14日 · Prominent T waves are associated with diffuse concave upward elevation of the ST-segment in most of the leads (except leads aVR and V 1 ). There are no reciprocal ST-segment depressions. PR segment depression in leads II, V 5, and V 6 and elevation in lead aVR support the diagnosis of pericarditis. 網頁tion, the ST-segment elevation is most marked in V 4, there is a notch at the J point (the junction between the QRS complex and the ST segment), and the ST segment is concave. The T waves are tall and are not inverted. Early repolarization of atrial tissue is

網頁The T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the T peak –T end interval. [1] In most leads, the T wave is positive. This is due to the repolarization of the membrane.

網頁Figure 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.
