3.1.3 EKG/Fibrillation Warm Up

What occurs in the conduction system of the heart during the P wave on EKG?

• SA node triggers depolarization in atria
• AV node triggers depolarization in ventricle

• Delay caused by the SA node
• Repolarization of the ventricle 

What is occurring in the conduction system of the heart during the QRS complex?

• SA node triggers depolarization in atria

• AV node triggers depolarization in ventricle

• Delay caused by the SA node

• Repolarization of the ventricle

What is occurring in the conduction system of the heart during the P-Q interval? Select all that apply.

• SA node triggers depolarization in atria
• AV node triggers depolarization in ventricle

• Delay at the the AV node

• Complete atrial contraction

Ventricular diastole occurs during which phase of the EKG?

• T - Q

• QRS - T

• S - T

• T - P

Heart rate cannot easily be determined. The ventricles are quivering/twitching. No consistent waves or complexes present on EKG.

• Atrial fibrillation

• Ventricular fibrillation

• Ventricular tachycardia

• Ventricular bradycardia
