ANSWER - True
An ECG accurately graphs atrial depolarization and atria re-polarization - CORRECT
ANSWER - False
The QRS complex shows the - CORRECT ANSWER - Depolarization of ventricles
The P wave shows the - CORRECT ANSWER - depolarization of atria
The T wave shows the - CORRECT ANSWER - repolarization of ventricles
The order of conduction through the heart is as follows: - CORRECT ANSWER - SA
Node->Atria->AV Node->bundle of HIS -> Bundle Branches ->Purkinje Fibers
Determine the R Wave axis of depolorization through the heart, given the following leads:
Lead l = +1
Lead 2 = +2
Lead 3 = +.5 - CORRECT ANSWER - +70 degrees
The PR segment of an ECG - CORRECT ANSWER - It indicates the period from atrial
systole to ventricular systole
