The normal T-wave Assessment of the T-wave represents a difficult but fundamental part of ECG interpretation. The normal T-wave in adults is positive in most…
The ST segment: physiology, normal appearance, ST depression & ST elevation The ST segment corresponds to the plateau phase of the action potential (Figure 13).…
QT duration and corrected QT (QTc) duration ECG interpretation always includes an assessment of the QT interval (QT duration). The QT duration represents the total time…
Physiology and ECG features of the P-wave, PR interval and PR segment The P-wave ECG interpretation usually starts with assessment of the P-wave. The P-wave…
The QRS complex (ventricular complex): normal and abnormal configurations and intervals A complete QRS complex consists of a Q-, R- and S-wave. However, all three…
