When observing an ECG, you will see many different deflections from baseline known as waves. These deflections represent various

electrical events taking place in the heart that give rise to the mechanical events that help move blood. In addition to the waves that can be observed, there are flat lines between waves and successive cardiac cycles called segments that also represent particular electrical events that take place in the heart. Finally, certain combinations of waves and segments, known as intervals, also identify important events recorded by the ECG. Match each of the following events with the correct phase of an ECG. Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
A. P wave
B. ST segment
C. QRS complex
D. PR segment
E. T wave
F. QT Interval
1. Atrial depolarization_____.
2. The ventricles are in their depolarized state____.
3. Total time it takes for the ventricular muscle to depolarize and repolarize____.
4. Ventricular depolarization____.
5. Conduction through the atrioventricular (AV) node____.
6. Ventricular repolarization____.
7. Conduction through the atrioventricular (AV) bundle____.

Answer:

1. Ventricular depolarization −−QRS complex

2. Total time it takes for the ventricular muscle to depolarize and repolarize −−QT interval

3. Atrial depolarization −−P wave

4. Conduction through the atrioventricular (AV) node −−PR segment

5. Ventricular repolarization −−T wave

6. The ventricles are in their depolarized state −−ST segment

7. Conduction through the atrioventricular (AV) bundle −−Q wave

Explanation:

ECG or electrocardiogram is the graphical representation of the heart's rhythm and electrical activity measured by electrical signals. The contraction of the heart shows electrical activity.

There are various deflections shows from baseline and known as specific waves and there are also some flat lines between waves called intervals. This atrial depolarization is called P wave and ventricular repolarization called T wave and the time between ventricular muscles depolarization ( QRS complex) and repolarization is QT interval. Conduction through the atrioventricular (AV) bundle is known as Q wave.

Is throwing a curve ball an example of potential or kinetic energy?
shutvik [7]
Throwing a ball is an example of kinetic energy. I do not have any proof or any reasons, but for now I just know that it's kinetic energy. You can also look it up and you'll see the answer automatically. Hope this helps :) If you want any proof, please feel free to ask me thru contact :)
