Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the average direction of ventricular depolarization during ventricular contraction. The direction of the depolarization (and thus the electrical axis) is generally alongside the...

The ECG does not record all the heart's electrical activity. The electrodes placed on the surface of the body record only the currents that are transmitted to the area of electrode placement. Therefore there are actually “silent” electrical areas of the heart. For example, the ECG is not ...
Must first exclude (on clinical grounds) other causes of right axis deviation such as cor pulmonale, pulmonary heart disease, pulmonary hypertension, etc., because these conditions can result in the identical ECG picture! The changes imposed in LPFB by MIs of different locations are depicted in...
On ECG, right axis deviation with normal sinus rhythm was seen. Ebstein Anomaly with Pregnancy: A Rare Case After an asystole episode lasting approximately 10-12 seconds, it was observed that the rhythm spontaneously turned back to normal sinus rhythm but as bradycardic. Atrioventricular Block in...
The normal has a heart rate of about 300 beats per minute and a mean electrical axis of + 86 degrees +/- 6.6 (SD). A 56% increase in right ventricular weight to body weight ratio was not associated with right axis deviation. The overall voltage produced on the ECG was increased in ...

High-speed 3D sensing and imaging are achieved via a parallel random LiDAR system that shows excellent resilience against cross-channel interference.Development and demonstration of...
