The ‘p’ wave on the electrocardiogram corresponds to Correct Answer Atrial depolarization

Concept:-

  • Echocardiography is a test that uses sound waves to produce live images of your heart. The image is called an echocardiogram.
  • This test allows your doctor to monitor how your heart and its valves are functioning.
  • The images can help them get information about:
    • Blood clots in the heart chamber.
    • Fluid in the sac around the heart.
    • Problems with the aorta, which is the main artery connected to the heart.
    • Problems with the pumping function or relaxing function of the heart.
    • Problems with the function of your heart valves.
    • Pressures in the heart.
  • In this, a chart is obtained with certain waves namely P, Q, R, S, T.
  • Each wave has an importance which is explained below
  • The P wave represents Arterial depolarization
  • The QRS complex represents ventricular depolarization
  • R wave represents the initial positive deflection
  • S wave represents the negative deflection following the R wave
  • Q wave is the first downward wave of the QRS complex and is often absent

Additional Information

Significance of ECG

  • ECG gives information about the rate and rhythm of the heart
  • It is a diagnostic tool for various heart conditions like hypertrophies, ischemia, arrhythmias, infarction, conduction problem, and pacemaker activities

Mistake Points

  • ECG does not provide information about mechanical activities
