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. During ventricle contraction (QRS complex), the heart depolarizes.
網頁2024年9月22日 · Figure 7.1 The shape of the ST-segment elevation. The ST-segment elevations in Panel A appear reassuring; indeed, this smooth, upwardly concave … 網頁The 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 …
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.
