Anyone want to explain QRS complex thing?
QRS complex is a trace displayed on an ECG which is a result of ventricular depolarisation/contraction, a likely question would be regarding the use of ECG traces to diagnose problems with the heart: Such as an electrocardiograph shows P Waves not followed by QRS complexes what could this indicate. The answere would be that their may be a problem with the AVN as the ventricles are not contracting so waves of electrical activity are not being passed onto the ventricles.
