Cardiovascular System and Cardiac Conduction Assessment

What is cardiac output calculated by?

• Heart rate multiplied by stroke volume
• Blood pressure divided by heart rate
• Stroke volume minus heart rate
• Systolic pressure times diastolic pressure

Which structure initiates the heartbeat?

• Bundle of His
• AV Node
• SA Node
• Purkinje Fibers

The ankle-brachial index is used to assess:

• Heart rhythm abnormalities
• Peripheral artery disease
• Cardiac output
• Blood pressure variations

Which pulse point is located behind the knee?

• Dorsalis pedis
• Femoral
• Tibialis posterior
• Popliteal

On an ECG, the P-R interval represents:

• Ventricular repolarization
• Atrial depolarization to ventricular depolarization
• Complete cardiac cycle
• Ventricular contraction only

The normal resting heart rate range for adults is:

• (40-50) beats per minute
• (60-100) beats per minute
• (100-120) beats per minute

Which pulse is commonly used to measure heart rate at the wrist?

• Carotid
• Brachial
• Radial
• Femoral

The Bundle of His is located:

• Between the ventricles
• In the right atrium
• In the left ventricle
• In the sinoatrial node

A cardiologist would most likely implant a pacemaker for:

• High blood pressure
• Tachycardia
• Bradycardia
• Hyperlipidemia

The QRS complex on an ECG represents:

• Atrial repolarization
• Ventricular repolarization
• Atrial depolarization
• Ventricular depolarization
