congenital tricuspid valve deformity leading to pathologic regurgitation

Some heart attacks are sudden and intense. Most heart attacks start slowly, with mild pain or discomfort. Often people affected aren't sure what's wrong and wait too long before getting help. Women are less likely to know they are having a heart attack simply because they go through so many different aches and pains throughout their lifetime and they do not always get the same symptoms as men can. Symptoms of a heart attack can inlclude: Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain Rapid, weak pulse. Cyanosis (blue colour around the face and lips). Collapse without warning. Chest discomfort or pain that may be crushing or squeezing or may feel like a heavy weight on the chest, especially on the left side Sweating. Shortness of breath. Nausea or vomiting. Pain that spreads from the chest to the neck, the jaw, stomach, or one or both shoulders or arms, especially the left Dizziness or lightheadedness. A fast or irregular heartbeat. Loss of consciousness. Excessive sweating Heartburn or abdominal pain. Anxiety, nervousness and/or cold sweaty skin. Skin that is clammy. Pale skin. Unexplainable fatigue. Some heart attacks are 'silent attacks,' or attacks where the victim experiences no symptoms at all. If you think you're having a heart attack, call 9-1-1 or your emergency medical system immediately.

In layman's term, angina pectoris means (severe) chest pain due to the lack of blood and oxygen supply of the heart (ischemia). The chest pain is not more than 10-15 minutes. It can be described as a feeling of tightness or squeezing and can radiate to the neck area, shoulder and arm, (particularly the left), and even the epigastrium. It is usually relieved by rest, and nitroglycerin.

Many things including the short term/acute effects of exericse and the Long term effects which are; Musculoskeletal response: increased blood supply; increase in muscle pliability; increased range of movement; muscle fibre micro tears Energy systems: phosphocreatine; lactic acid; aerobic; energy continuum; energy requirements of different sport and exercise activities Cardiovascular response: heart rate anticipatory response; activity response; increased blood pressure; vasoconstriction; vasodilation Respiratory: increase in breathing rate (neural and chemical control); increased tidal volume Cardiovascular system: cardiac hypertrophy; increase in stroke volume; increase in cardiac output, decrease in resting heart rate; capillarisation; increase in blood volume; reduction in resting blood pressure; decreased recovery time; increased aerobic fitness Muscular system: hypertrophy; increase in tendon strength; increase in myoglobin stores; increased number of mitochondria; increased storage of glycogen and fat; increased muscle strength; increased tolerance to lactic acid Skeletal system: increase in bone calcium stores; increased stretch in ligaments; increased thickness of hyaline cartilage; increased production of synovial fluid Respiratory system: increased vital capacity; increase in minute ventilation; increased strength of respiratory muscles; increase in oxygen diffusion rate Energy systems: increased aerobic and anaerobic enzymes; increased use of fats as an energy source (taken from a website - not my own work)

The average total serum cholesterol level for a woman in her 30s is approximately 185. (Anything just over 200 should be treated dietarily, with restriction of sweets, saturated fats and fried foods. Anything over 220 should be treated dietarily AND medicated with cholesterol-lowering agents, ideally.)

Yes! One of my best friends has only half a heart. The left half! She has only her left atrium and ventricle, and had to be delivered months early so her "tubing" could be rearranged. It's not easy, and extremely risky, but people can survive. She is 19 right now and will be getting surgery this summer to get some new parts to replace the old ones that she got when she was born. She has a really cool scar that goes all the way down the middle of her chest :D

Electrocardiograph (ECG, or EKG [from the German Elektrokardiogramm]) is a transthoracic interpretation of the electrical activity of the heart over time captured and externally recorded by skin electrodes.[1] It is a noninvasive recording produced by an electrocardiographic device. The etymology of the word is derived from the Greek electro, because it is related to electrical activity, cardio, Greek for heart, and graph, a Greek root meaning "to write". In English speaking countries, medical professionals often write EKG (the abbreviation for the German word elektrokardiogramm) in order to avoid confusion with EEG.

In animals such as Alligators or Turtles, the intercardiac shunt is a section of the heart that allows them to not have to breathe underwater for days at a time. Exactly how, i don't know.

i think that's a good thing... i know someone who recently did a fitness test for a job n had to get his resting heart rate checked and it was 56, apparently for this, the lower was better

In the right hand side of the heart at the junction of the right ventricle and the pumonary artery. Its function is to make sure that deoxygenated blood goes to the lungs and does not flow back into the heart. It's also known as a semi-lunar valve.

90% blockage is not a heart attack (myocardial infarction) but could verly likely lead to one. The arterial plaque can "flake" off causing a disruption in the arterial wall thus activating platelets to form a "platelet plug". This aggregation (gathering) causes a thrombus (blood clot) which can become an embolus (traveling blood clot) which can make its way, via the blood stream, to a coronary artery. This in turn would block O2 rich blood from entering the heart muscle. This is an example of how blockage can lead to a heart attack! . Nick J.

When a person is evaluated for high blood pressure), 2 values are recorded: systolic and diastolic blood pressures. Systolic (the higher number) is the pressure in the arteries when the heart contracts; diastolic (the lower number) is the pressure when the heart rests between contractions. A blood pressure reading is recorded as systolic /diastolic pressure, or "systolic over diastolic." Both systolic and diastolic blood pressures are measured in millimeters of mercury (mmHg). An example of how to read a blood pressure measurement is "120 mmHg/80 mmHg" or "120 over 80." High blood pressure in adults is defined as having either a systolic pressure of 140 mmHg or more, or having a diastolic pressure of 90 mmHg or more. In some people with high blood pressure, both systolic and diastolic pressures are high. However, older people often have a higher systolic pressure with a normal. This condition is called isolated systolic hypertension, which is still considered high blood pressure. In older adults because the arteries reduce in elasticity, they do not expand as easily causing an increase in the systolic blood pressure (Imagine the same quantity of blood flowing through a vessel that doesn't expand. It gets really crammed in there causing systolic blood pressure to increase). But because diastolic pressure is the minimum pressure exerted on the arteries during diastole, there isn't much distension and contraction of the arteries. Thus, reduced elasticity does not effect diastolic pressure causing a normal blood pressure reading.

underactive contracyin of heart muscle

My father has had blood clots and is still high-risk to getting more. He has had no issues with flying while he has had blood clots. His has been in his legs, and all he said to do was wiggle your toes. If it is a longer flight, be sure to get up and move around when you can. The longer you sit, the worse it is.

No. Could be quite dangerous to take it too, so don't!

It is known that dengue fever can affect the heart in several ways, including weakened force and speed of contraction and slowed pulse rate. Along with some other febrile illnesses ( illnesses with fever) dengue may demonstrate "relative bradyardia", that is, heart rate lower than would be expected for a given level of fever. The mechanism is not clear but may be mediated through the immune system or may be related to an inflammation of the heart. The presence of a relatively slow heart rate in the presence of a high fever is not diagnostic for dengue but indicates the need for testing for dengue, or if testing is not available is probably sufficient indication to treat for dengue. Finally, in the terminal stages of many conditions, including severe hemorrhagic dengue fever, massive loss of fluids out of the circulatory system into the tissues may result from damage to the capillaries (the smallest blood vessels). In these circumstances the body may not be able to compensate for the low circulating volume and blood flow to the vital organs, including the brain and the heart itself may be diminished to critical levels resulting in slowing of the heart, usually as a precursor to death. This cause of bradycardia is more properly regarded as part of the complex process known as "shock" rather than as a symptom of any specific disease.

QRS in the context of cardiovascular health has reference to the electrical pattern of the heart. This is readily seen on an ECG (electrocardiogram). The Q wave is the first downward deflection after a P wave, the R wave is the first upward deflection following a P wave, and the S wave is the downward deflection following the R wave. Taken together the QRS complex represents the electrical activity of the heart during systole: the phase of the heart during which ventricular emptying occurs.

I don't know but brain damage occurs after 3 minutes. Heart failure means that your heart can no longer pump blood adequately through the heart and out to the rest of the body. The blood literally "backs up" into the pulmonary system (lungs) and your lungs become too fluid filled to exchange oxygen and carbon dioxide. This process deprives your body's tissues/organs from the oxygen it needs and they begin to fail. This can be a very slow process if it is a chronic condition, or it can occur very quickly depending on how quickly the heart function is failing, and why (example: heart failure due to chronic high blood pressure or heart attack which results in heart tissue death)
