Raises blood pressure, which causes the heart to work harder than normal. Increases pulse.

no he was not i have figured this out like this well in the author chat with the New York public library asked him he said no, then when i looked it up again i went to a different author chat with gary he also said no, in conclusion my answer s no because that is what he said.

This statement likely indicates that the vertebral arteries are open, with good blood flow traveling in the typical direction without any narrowing or blockages present. The term "codominant" suggests that both sides of the vertebral arteries are contributing equally to blood supply in the brain.

A fast heartbeat is called tachycardia. It is typically defined as a heart rate greater than 100 beats per minute at rest. Tachycardia can be caused by various factors such as stress, excitement, or underlying medical conditions.

The Guinness World Record for the most heart catheterizations performed in one minute is 9 and was achieved by Dr. Suresh S. Pujari (India) in Maharashtra, India on 27 June 2019.

In an echocardiogram, "echo" refers to the use of sound waves to create images of the heart. The sound waves bounce off the heart structures and are converted into images that show the heart's size, shape, and how well it is functioning. This non-invasive test helps evaluate the heart's overall health and diagnose various heart conditions.

HDL stands for high-density lipoprotein, which is commonly known as "good" cholesterol. HDL helps remove excess cholesterol from the bloodstream and transport it to the liver for processing and excretion. Having high levels of HDL is associated with a lower risk of heart disease.

The subclavian vein can be located by palpating the clavicle and the sternocleidomastoid muscle. The vein is typically located just above and slightly lateral to the midpoint of the clavicle. It can also be located by using ultrasound guidance.

T inversion in lead V3 on an ECG may indicate various conditions such as myocardial ischemia, ventricular strain, or electrolyte imbalances. It is important to consider the clinical context and the overall ECG findings when interpreting T-wave inversions in lead V3. Additional testing and evaluation may be necessary to determine the underlying cause.

A non-ST elevation myocardial infarction (NSTEMI) is a type of heart attack where the blood flow to the heart is partially blocked. It is considered a medical emergency and requires prompt treatment to prevent further heart damage. Treatment may include medications, such as antiplatelet drugs and anticoagulants, or procedures like angioplasty to restore blood flow to the heart.

There is no specific term "subclarian" in common use. It could be a misspelling or a specialized term not widely recognized. Can you provide more context or clarify your question so I can assist you better?

It's generally recommended to have someone accompany you to a nuclear stress test for support and to drive you home if needed. The stress test can be physically demanding, and having someone with you can make the experience more comfortable.

That is wrong

It is the Left Ventricle

When a person is starving, their body breaks down protein for energy, leading to an increase in urea production as a byproduct of protein metabolism. Urea is then released into the blood and its concentration rises due to the increased breakdown of proteins for energy in the absence of sufficient food intake.

Is this a trick question? Arteries carry oxygenated blood to the rest of the body but deoxygenated blood to the lungs. It is the veins that return blood to the heart, from body and lungs. The only difference is that the veins carry oxygenated blood this time whereas in the systemic circulation, the blood is deoxygenated.

1. Ineffective breathing pattern related to decreased lung expansion
2. Impaired gas exchange related to decreased lung function
3. Acute pain related to inflammation of the pleura
4. Risk for infection related to accumulation of fluid in the pleural space

The major signs of a heart attack are chest discomfort, discomfort of areas in the upper body, shortness of breath, cold sweat, nausea, or feeling lightheaded.

Acute cerebrovascular disease is the hardening of the arteries that supply blood to the brain. A cerebrovascular accident is when a stroke occurs due to a blood clot in the arteries leading to the brain.

They are essentially the same.

Cardiology is an internal medicine specialty dealing with the diagnosis and treatment of disorders of the human heart.

The left ventricle pumps blood into the aorta through the aortic semi-lunar valve.

Female sex hormones, such as estrogen and progesterone, have been found to have an impact on heart rate and palpitations. Estrogen, in particular, has been observed to increase heart rate, while progesterone has a more variable effect.

Estrogen, which is primarily produced by the ovaries, has been shown to have a direct effect on the cardiovascular system. It can stimulate the release of nitric oxide, a substance that relaxes blood vessel walls, leading to vasodilation. This dilation of blood vessels can result in an increase in heart rate. Additionally, estrogen has been found to affect the autonomic nervous system, which controls heart rate, by increasing sympathetic activity and decreasing parasympathetic activity.

Progesterone, on the other hand, has a more complex influence on heart rate. It has been found to have both stimulatory and inhibitory effects, depending on the concentration and the phase of the menstrual cycle. In the early stages of the menstrual cycle, when progesterone levels are low, it can have a stimulatory effect on heart rate. However, during the luteal phase, when progesterone levels are high, it may have an inhibitory effect on heart rate.

Palpitations, which are characterized by a rapid or irregular heartbeat, can also be influenced by female sex hormones. Estrogen has been associated with an increased risk of palpitations, particularly during times of hormonal fluctuations such as pregnancy, menopause, or during the menstrual cycle. This may be due to the effects of estrogen on the autonomic nervous system, which can lead to increased sympathetic activity and subsequent palpitations.

In summary, female sex hormones, specifically estrogen and progesterone, have a significant impact on heart rate and palpitations. Estrogen tends to increase heart rate, while progesterone has a more variable effect. Understanding these hormonal influences is important in managing cardiovascular health, particularly in women, and may help in the development of targeted interventions for heart-related conditions.
