Questions Related to cardiac regulation and disorders
Which of the following is correctly matched for diseases in humans?
-
Hypertension increase in sytolic blood pressure about 130-140 mm hg and diastolic blood pressure 90-100 mm hg.
-
Arteriosclerosis hardening of arteries due to deposition of calcium salts resulting in plaque formation.
-
Atherosclerosis inelastic arteries.
-
All of the above.
A. The systolic blood pressure is the pressure that develops in arteries when the ventricles contract and the diastolic pressure develops when the ventricles relax. The normal range of blood pressure is 120/80 mm Hg. In hypertension, the blood pressure elevates to 130-140 mm Hg systolic and 90-100 mm Hg diastolic pressure.
Hypertension occurs when blood pressure is consistently above
-
120/180
-
140/180
-
120/85
-
140/90
Hypertension is caused due to an elevation in the pressure applied during the blood flow in the blood vessels. Blood pressure is expressed by two measurements, the systolic and diastolic pressures, which are the maximum and minimum pressures, respectively, in the arterial system. The systolic pressure occurs when the left ventricle is most contracted, the diastolic pressure occurs when the left ventricle is most relaxed prior to the next contraction. Normal blood pressure at rest is within the range of 100–140 millimeters mercury (mmHg) systolic and 60–90 mmHg diastolic. Hypertension is present if the blood pressure is persistently at or above 140/90 mmHg for most adults.
Hypertension occurs due to
-
Smoking
-
Obesity
-
Stress
-
All of the above
High blood pressure is called as
-
Hypotension
-
Hypermetropia
-
Hypertension
-
Myopia
Hypertension is the term for high blood pressure when blood pressure is higher than normal (normal 120/80 mmHg). In this measurement 120 mm Hg (millimeters of mercury pressure) is the systolic, or pumping pressure and 80 mm Hg is the diastolic, or resting pressure. If repeated checks of blood pressure of an individual are 140/90 (140 over 90) or higher, it shows hypertension. High blood pressure leads to heart diseases and also affects vital organs like brain and kidney.
Pace maker of the heart is
-
S.A. node
-
A.V. node
-
A .V. septum
-
L A. septum
S.A node called as pacemaker ,node of keith and flack heart , brain of heart ,pulsation centre.
An artifical pacemaker is implanted subcutaneously and
connected to the heart in patients
-
Having 90% blockage of the three main coronary arteries
-
Having a very high blood pressure
-
With irregularity in the heart rhythm
-
Suffering from arteriosclerosis
When irregularity in the heart rhythm occurs, normal heart rhythm can be reared and maintained by surgically implanting an artificial pace maker, a device that sends out small electrical current to stimulate the heart to contract.
Increase in blood pressure is
-
Arteriosclerosis
-
Atherosclerosis
-
Hypertension
-
None of the above
What is correct regarding blood pressure?
-
105/50 mm Hg makes one very active
-
100/55 mm Hg is considered at ideal blood pressure
-
190/110 mm Hg may harm vital organs like brain and kidneys
-
130/90 mm Hg is considered as high and requires treatment
A patient was administered a chemical agent called Guanfacine hydrochloride after the patient showed the symptoms like shortness of breath and headache. Guantacme hydrochloride is a known stimulant of central $\alpha - 2 $ -adrenergic receptors of the medulla regulating the sympathetic nervous system. The patient in this case must be suffering from
-
Hypertension
-
Hyperslimulation
-
Hyperpolarization
-
None of the above
Alpha 2 receptors in the brain stem and in the periphery inhibit sympathetic activity and thus lower blood pressure.
Which of the following should a heart patient firmly avoid?
-
Cream
-
Mango
-
Rice
-
Milk
Heart diseases can be caused due to a number of factors such as age, gender, tobacco use, physical inactivity, excessive consumption of alcohol, unhealthy diet, obesity, family history of cardiovascular disease, hypertension, diabetics, high cholesterol levels , psychosocial factors and pollution, However, a patient with any form of heart disease should avoid cream as intake of dietary trans fat tends to perturb the body's ability to metabolize the essential fatty acids which lead to changes in the phospholipid fatty acid composition of the main artery of the heart. This tends to increase the risk of coronary heart disease.
