- The electrical axis of the heart (heart axis): ECG & physiologyThe electrical axis of the heart (heart axis) Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the…
- The T-wave: physiology, variants and ECG featuresThe 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 precordial and limb…
- The ST segment: physiology, normal appearance, ST depression & ST elevationThe ST segment: physiology, normal appearance, ST depression ST elevation The ST segment corresponds to the plateau phase of the action potential ( Figure 13 ). The ST segment…
- QT duration & corrected QT (QTc) duration: ECG features & implicationsQT 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 for…
- P-wave, PR interval, PR segment: physiology, criteria & ECG findingsPhysiology 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 is a small, positive…
- Answer to ECG quiz 5The ECG shows AV-block III (complete heart block) . P-waves are not related to QRS. PP-interval is constant, but independent of RR-interval, which is also constant. Atria and…
- The QRS complex: ECG features of the Q-wave, R-wave, S-wave & durationThe 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 waves may not be…
