Web20 de dez. de 2024 · An electrocardiogram, abbreviated as an ECG or an EKG, measures the electrical activity in the heart. This helps to find out any abnormalities in the activity of the heart. The process of EKG is based on the fact that every beat of the heart is accompanied by electrical impulses traveling through it. These signals which control the … WebTo help evaluate a QT interval independent of heart rate, the corrected QT interval (QTc) can be calculated: The normal range for the QTc is 0.36–0.44 sec.
