Why is your chest fluttering and feeling tight?
Chest flutters are also know as PVCs or Premature Ventricular Contractions. The can be caused from anxiety, fatigue, too much exercise.
consider the poles as on the right hand side of s plane ie. (s-1) or (s-2)
Consider the simple case in which transfer function is 1/(s-2) ie.pole 2 in the RHP of s plane
if we take the inverse laplace transform we e^2t u(t)......
our output is Ae^2t u(t).....
immediately we can recognize that e^2t for t>0 is not converging ..as t->infinity the output also tends to infinity...
but for system with transfer functio 1/(s+2) the inverse is e^-2t and it is quite clear that it is a converging or bounded or stable
I think transplanted organs are not generally re-transplanted into another patient (if the first dies). Simply since the organ has already been put under a lot of pressure being moved from the donor to the first recipient - there's a higher risk of failure if it were transplanted again. And there's the possibility that the organ could be getting quite old by that time. Depending on how long the first recipient lived, the organ could also have been subjected to a lot of immunosuppressive drugs, which can compromise it's ability to work over a long period.
Why is it important to have early detection of cancer?
In some cases, early detection of cancer can make treatment simpler with fewer side effects. It may also increase the chances of long-term survival.
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.

What is the path followed by the blood when it supplies and drains the heart muscle?
The path followed by the blood when it supplies and drains the heart muscle
Does heartache cause heart problems?
