Heart

It all depends upon the severity of the injury. If it is a mild infarction, and relatively little cardiac muscle is affected, then the odds are quite good. If it is a massive myocardial infarction, then the odds would be quite poor.

elastic tissue, I had this question as part of my online assignment, I answered it and it was correct ;)

The four chambers are;

Left atrium

Right atrium

Left Ventricle

Right Ventricle

The two upper chambers are called atria (singular: atrium) and the two lower chambers are called ventricles.

There are four chambers of the heart - the right atrium, left atrium, right ventricle and left ventricle.

Surgeons use math to get the beat of your Heart and any kind of gut like the Brain

The atria are on the top, and ventricles on the bottom.

The atria are smaller, and the ventricles bigger.

The atria receive blood coming into the heart, and the ventricles send blood out of the heart.

The contraction of the atria end diastole, and the contraction of the ventricles end systole.

Cardiac cycle, which is made up of atrial and ventricular systole and diastole.

When you breathe, the air that goes in your lungs gets absorbed through the thin tissue that your lungs are made up of. This oxygen is transmitted to the heart, which pumps blood all around the vascular system. Blood carries the oxygen and releases it wherever the oxygen is needed.

Two heart sounds "lub-dub"

Why do you need to know and why don't you?

The deoxygenated blood enters the right atrium from the superior and inferior vena cava. The deoxygenated blood then goes through the tricuspid valve into the right ventricle. From the right ventricle the deoxygenated blood flows through the pulmonary valve to the lungs to be oxygenated. The blood goes to the lungs through the pulmonary arteries to get to the lungs. At the lungs diffusion (movement of things between a higher concentration and a lower concentration) occurs and the higher concentration of oxygen in the lungs (more specifically alveoli) goes to the lower concentration of oxygen in the capillaries (extremely small blood vessels). The same thing occurs with Carbon Dioxide except it is going from the capillaries from the lungs. The now oxygenated blood flows from the lungs to the left atrium through the pulmonary veins, where it is sent to the left ventricle through the mitral valve. From the left ventricle the oxygenated blood goes through the aortic valve, into the aorta, and all throughout out the body.

* All patients being transported for chest pain should be managed as if the pain were ischemic in origin unless clear evidence to the contrary is established. * If available, an ALS unit should transport patients with hemodynamic instability or respiratory difficulty. * Prehospital notification by Emergency Medical Services (EMS) personnel should alert ED staff to the possibility of a patient with MI. EMS personnel should receive online medical advice for a patient with high-risk presentation. * The American Heart Association (AHA) protocol can be adopted for use by prehospital emergency personnel. This protocol recommends empirical treatment of patients with suspected STEMI with morphine, oxygen, nitroglycerin, and aspirin. * Specific prehospital care includes the following: * ** Intravenous access, supplemental oxygen, pulse oximetry ** Immediate administration of aspirin en route ** Nitroglycerin for active chest pain, given sublingually or by spray ** Telemetry and prehospital ECG, if available * EMS protocol should be formulated to strongly consider taking patients with suspected MI/ACS, and certainly patients with STEMI, to facilities capable of PCI if geographically possible. * Prehospital thrombolysis allows eligible patients to receive thrombolysis 30-60 minutes sooner than if treatment were given in the ED; however, prehospital thrombolysis is still under investigation.

Your heart pumps blood constantly. The blood is always moving through your arteries, veins, and capillaires. The arteries have muscle on their outside, which also squeezes blood. Veins do not have extra muscle, but they do have one-way valves inside them. These valves let blood go through in one direction as the heart pumps. Then, as the heart relaxes, the valves shut so that the blood doesn't slip backwards. In this way, the blood can move up from the feet back to the heart.

No. A heart attack (called a myocardial infarction, or MI) is an acute event caused by lack of oxygen and metabolic substrates to a particular part of the heart, or the entire heart in certain conditions, such as shock.

Heart failure, as it is frequently called, is actually a misnomer. It refers to a relative weakness of the heart, causing its pumping action to not be as efficient as it once was. For instance, a healthy heart has a pumping efficiency (Ejection fraction = the percentage of blood in the ventricle that is pumped out with each heart beat) of about 55-60%. In "heart failure," the ejection fraction is less than this.

Heart failure is frequently seen after heart attacks, but may be caused by many other conditions as well.

NO. Calcium is actually one of the more essential nutrients that are needed in the human's body. It is fatty acids and obesity that gives you heart problems, not calcium.

Blood starts on the SA node. When the atria are full, the electricity goes across either side to the left and right atria. It tells them to contract, pushing blood into the ventricles. The electricity then arrives at the AV nodes. Then it goes to the bundle of his, still in the ventricles. Here the electricity divides onto either side of the septum. The electricity goes through the Purkinje fibers, on the hearts wall. It spreads quickly through the ventricles, causing them to contract. This happens over and over, causing heart beats.

My heart rate has jumped as well. When I was working out the other day the machine started yelling at me b/c my heart rate was so high. Is this dangerous at all? Should I be working out less b/c of it?

I have only been on strattera for three days. Everyone is touting it as a non-stimulant , so far its effects dont seem much different that adderal or other stimulant meds. It definitley helps me focus and concentrate but along with it comes increased heart rate, and appetite suppression.

I am a 47 yr old woman, who was RX'd Strattera about 4 months ago......worked fine until about 4 weeks ago.....my blood pressure has jumped, my pulse faster than ever, constant upset stomach, dizzy spells with increasing frequency, insomnia, daily abdominal cramping......will be discontinuing today, as I cannot tolerate this and am concerned about the heart symptoms....and the dizziness is becoming alot worse, a daily thing that causes the room to spin-----and incapacitates me. In my line of employment, this could be dangerous for myself and others...it's gotta go !

I am 49 year old and very physically active male. I do long distance road riding on a bike. The increase in heart rate has diminished my stamina. I am on 80mg of Strattera and will reduce it to 60mg to see if that makes an improvement.

I am only 21 years old, and am actually concerned about my health because of how much Strattera has increased my heart rate. I cannot discontinue it because I need to concentrate for college, yet just a fe wdays ago I went to give blood and was denied as my heart rate was 120 bpm.

I suggest talking to your doctor, as I will

Typically, males have lower heart rates then females of comparable condition (similar age, weight, fitness, etc.)

See the related links for charts related to resting heart rates by age, gender, and fitness.

This valve has different names. It is the LAV valve or Mitral Valve or Bicuspid valve.

Another name for the human heart is a cardiac muscle.

The heart is a pump that distributes blood to the organs of the body. The heart is made of 4 chambers. The top 2 collecting chambers are called atria; the bottom 2 ejecting chambers are called ventricles.

It is the surgery which the opening of the literal heart occurs. It is when surgeons perform the operation to fix the arteries, veins or capillaries connected to the heart. Or it can also be the main parts of the heart like the Aortic Valve, Superior and Inferior Vena Cava, the atria or the ventricles.

Simple answer: Veins

Complex answer: a series of blood vessels (excluding arteries) carries deoxygenated blood from the body to the heart. Where the blood is then passed through an oxygenating process with the lungs.

Another answer: pressure caused by the beating of the 4 chamber heart.

"Stronger" heart rates generally denotes a slower heartbeat. As a whole I believe men do as they're more physically adept (on average). Obviously this cannot apply to individuals or even different races (it is known that people of African descent generally have more heart problems, not to be racist).
