Left ventricle
Increased pressure in the ventricles means the heart has increased stress pumping blood to the respiratory system/ body.
Stress can cause an increased heart rate and increased blood pressure. Continued stress can lead to tachycardia and continued high blood pressure. You first need to have a doctor examine you to make sure the tachycardia is from stress rather than a physical cause. If from stress, build in ways to relax during the day. Get exercise; walking helps reduce stress. Do meditation or listen to soothing music. Even a warm bath can help some people feel less stressed.
Your heart beats fast because when your brain gets a sudden fright it contracts all muscles and that uses oxygen and it also contracts the heart and so the heart needs to pump blood around more often so the muscles can continue to react in the state of emergency in rapid speed. I hope this answers your question.
No, dead muscle is dead muscle - however the genius of the human body is that it can adapt. If there is enough of the heart sill alive it will increase its effort to compensate for what died. Many people live long lives after heart attacks. It is best to catch an attack before the muscle dies and have surgery to rework blood paths to the starved muscle. Bypass and shunts have worked restoring blood flow to struggling hearts restoring health and longevity. But a dead muscle is a dead muscle so treatment before a major attack is critical.
Sounds like you have lack of oxygen. If you have sleep apnea this can severly hinder the oxygen level in the blood and possibly lead to a heart attack because of the stress that the heart is under during the sleep process. If you have apnea, you actually stop breathing for a duration of time, usually 5-20 seconds, then your body kicks into a response which forces you to breath. The heart works harder to get the oxygen to the body, but beause the oxygen is lacking, it adds undue stress to the heart. I would contact your Dr. about this or maybe another possibility is Chronic Fatigue Syndrome...
The hyperglycemia caused by stress would lead to an increased secretion of insulin, which would than lower blood glucose. As a consequence, the blood glucose would not be sustained to deal with continued stress.
increased
When the stress remains constant even when the time is increased is known as instantaneous stress.
Stress can produce chronic increases in adrenaline levels, and have related those changes to an increased risk of heart disease. It can constrict the coronary arteries in such a way that blood flow to the heart muscle is reduced. Finally may lead to death
yes it does. If you do what you like then you are happy and thus by the power of all that is you.... Your stress is reduced
Hypertension means high blood pressure, which can be increased by stress.
sometime increased HCl secretion with acute stress but chronic stress causes HCl production to decrease
Toxic
When stress is linked to increased psychological disorders, it is referred to as a stress-related mental health issue or a stress-induced psychological disorder.
The stress level will be increased. In this case, the word "affect" should be used.
This would be cortisol, which is released in increased amounts when an organism is under sustained stress.
If you use your schedule properly, you can gain better time management skills, increased productivity, reduced stress from feeling more organized, and the ability to prioritize tasks effectively.
