¶ … hearts spend in diastole?
Heart relaxation
Heart failure is a common concept in the contemporary society and in spite of the fact that the masses are virtually bombarded with information regarding this condition, it appears that many are still unable to take on the attitudes needed in order for them to avoid having heart problems. Until recent years, the majority of people familiarized with heart problems were only acquainted with ideas regarding systolic dysfunctions. This was owed to heart muscles weakening and no longer being able to pump blood efficiently.
In the present, the world of medicine was able to discover much more information about diastolic dysfunctions and about how they affect the body and the heart in particular. In contrast to how many thought, heart failure does not necessarily have to be caused by weakened heart muscles. Instead, it can be caused by stronger heart muscles that are unable to relax properly and that are thus pumping blood inefficiently.
While it would be safe to say that individuals need to concentrate on ways of providing their hearts with the time it needs to relax and while in many cases this is approximately two thirds of the day, there are many variables that can influence...
The process that the heart goes through while relaxing is particularly complex and this is why it is essential for individuals studying a heart's functioning to understand whether or not muscles in the heart work efficiently.
Even with the progress that has been made in recent years in the world of medicine, physiologists and clinicians are still unable to fully understand the way the heart relaxes. "From a physiological point-of-view, rapid and complete relaxation is a prerequisite for cardiac output adaptation to changes in loading conditions, inotropic stimulation, and heart rate. From a clinical point-of-view, the relaxation phase could be impaired earlier and more profoundly than the contraction phase in numerous cardiac diseases." (Chemla et. al.)
The time a heart would need in order to relax largely depends on the condition of the individual. In some cases when individuals have perfectly normal heart muscles, the relaxation period can be lower while in other cases when people have either systolic or dystolic dysfunctions, their hearts might require longer periods of time in order to relax. "In the healthy human heart, the rate and extent of relaxation depend mainly on actomyosin cross…
