Qtc in wide qrs
WebA long QT interval is diagnosed by ECG showing prolongation of the rate-corrected QT interval (QTc). Normal QTc intervals are about 0.40 second for men and 0.41 second for women and are considered prolonged when > 0.47 second for men or > 0.48 second for women. However, given the multiplicity of factors affecting the QTc, a normal QTc does … WebNov 1, 2024 · Calculate QTc or JTc Ventricular conduction delay from bundle branch block or ventricular pacing manifests as widening of the QRS (QRS ≥ 110 ms) due to slowed, cell-to-cell depolarization of the myocardium rather than rapid conduction through the His-Purkinje system.
