The P-Wave indicates

• Depolarization of both atria

• Depolarization of right ventricle

• Depolarization of left ventricle

• Atria to ventricular conduction time

Ventricular muscle excitation is indicated by

• P wave

• The QRS complex

• U wave

What does the Depolarization of ventricles initiate?

• Atrial diastole

• Atrial systole

• Ventricular systole

• Ventricular diastole

What does the T-wave represent in an ECG?

• Atrial diastole

• Atrial systole

• Joint diastole

• Ventricular diastole

Counting the number of QRS complexes, which of the following can be interpreted?

• Rate of heartbeat

• Rate of breathing

• Cardiac output

• Stroke volume

What do Depolarization and Repolarization initiate in different chambers of the Heart?

ECG depicts the Depolarisation and Repolarisation processes during the Cardiac Cycle. In the ECG of a normal healthy individual one of the following waves is not represented, which one is that?

• Depolarization of atria

• Repolarisation of atria

• Repolarisation of ventricles

• Depolarisation of ventricles

In which part of the heart does deoxygenated blood from the body enter?

• Pulmonary veins

• Pulmonary arteries

• Aorta

• Vena cava

One of the four chambers of the heart that receives oxygenated blood from the lungs and pumps it through the mitral valve to the left ventricle.

• Right atrium

• Left atrium

• Right ventricle

• Left ventricle

What is the formula for Cardiac output?

• stroke volume x heart rate

• heart rate x end-diastolic volume

• stroke volume x end-systolic volume

• end-systolic volume - end-diastolic volume
