The right answer is Electrocardiography (or Electrocardiogram).
In a typical plot, one can notice five characteristic waves. They are called P, Q, R, S and T. The illustration below shows what a normal electrocardiogram looks like:
* the P wave marks the depolarization during the contraction of the atria;
* the PR interval indicates the time required to transmit the electrical impulse of the sinus node of the atria to the ventricular muscles;
* the QRS complex marks depolarization and ventricular contraction;
* the QT interval corresponds to the global ventricular repolarization;
* T wave refers to the end of ventricular repolarization.
The diagnostic test that records the electrical activity of the heart is called ECG or Electrocardiogram. An ECG is a painless and simple test, which uses electrodes arranged and attached to your skin, and records the activity of the heart. ECG detects any abnormal rhythm and pattern of the heart beat and this helps doctors in diagnosing arrhythmias.
Answer:
Acquired immunodeficiency Syndrome (AIDS) is a syndrome caused by the human immunodeficiency virus (HIV). Up till today, there is not a proper cure for the syndrome but specific drugs can be given to the patient to control or reduce the virus in the patient. Some of the medicines used are:
Lamivudine (Epivir, 3TC), Tenofovir (Viread, TDF), Abacavir (Ziagen, ABC), Indinavir (Crixivan, IDV) etc.
The treatment of AIDS is nowadays far better than the initial years in which AIDS became common. Scientists could not make medicines for reducing the HIV virus and also did not know how this virus spread from one person to another.
In the near future, scientists are working hard to produce vaccines for developing immunity against the virus and also looking for genetic engineering methods to treat AIDS.
The glycemic index predicts the way certain foods affect blood sugar levels.
The correct answer is B. because it's true that Capillaries are connected between the arteries and veins and that Pulmonary arteries transport blood low in oxygen from the right ventricle to the lungs. But veins carry blood towards your heart so B isn't true
