An novel potentially life-threatening cardiac arrhythmia syndrome identified with ECG The ECG may be used to diagnose several cardiac genetic disorders, such as Brugada syndrome, long
The electrical axis of the heart (heart axis) Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical
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 assessment of the QT (QTc) duration. The QT duration represents the total time for de-
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
