Which of the following parts of an ECG represents the depolarization of the atria? Which of the following occurs in the cardiac cycle if the impulse triggered at the sinoatrial node never closes? What is the importance of the valves of the heart? a. regulation of heart...
In the ECG pattern of heart conduction, why is there no deflection of the atrial depolarization? O Because the 2 atrial chambers are in systole O Because the ventricles are in diastole O Because the SA node is inactive O Because the AV node is inactive O The c...
