Answers
Answer:
option A
Explanation:
tachycardia is an abnormal condition where heart beats abnormally fast
Answer:
(A) The heart beats abnormally fast.
Explanation:
Tachycardia is shown by the heart which beats abnormally fast.
(A) The heart beats abnormally fast.
Tachycardia is the medical term for more than 100 beats per minute. Many irregular heart rhythms (arrhythmias) can cause tachycardia. A fast heart rate is not always alarming. For example, heart rate usually increases during exercise or in response to stress.
(B) The heart beats abnormally slow.
If you have bradycardia, your heart beats less than 60 times per minute. Bradycardia can be a serious problem when the heart rate is very slow and the heart cannot pump enough oxygenated blood around the body. If this happens, you may feel dizzy, very tired or weak and short of breath.
(C) The right atrium of the heart stops working.
When this occurs, the heart is unable to pump oxygen-rich blood from the lungs to the heart's left atrium, into the left ventricle and on through the body and the heart has to work harder.
(D) The left ventricle pumps less blood to the aorta.
The left and right ventricles are stronger pumps. The left ventricle is the strongest because it has to pump blood out to the entire body.
Therefore, option (A) is the correct answer.
