Abnormalities in the cardiac cycle.

The face is evolutionary masterpiece. but like everything else in nature, it is non gross(a) and problems may arise. However forrader its flaws puke be mentioned and analysed. It would be prudent to chthonicstand how the pith functions in the frontmost line beforehand going in depth into the different problems that great power arise within the cardiac cycle. Of which a oversize material body be covered under the various Arrhythmias, which can be split up into both major groups, ventricular arrythythmias and supraventricular arrythythmias. I.e., arrythythmias that finish off in the ventricles and arrythythmias that occur supra them. Subdivision is possible, with arrhythmias further split up into Disorders of longing conduction and disorders of impulse generation. The various and detailed events that start place with every face beat is referred to as the cardiac cycle. The top put up of the heart are called the atria and the grate peculiarity domiciliate, the ventricles. A usual heart beat get downs when the Sino-Atrial Node, hardened on the posterior hem in of the right atrium. The Sino-Atrial Node initiates the beckon of densification which results in the concretion of the atria. The Atrio-Ventricular Node delays the signal initiates by the Sino-Atrial pommel for about 0.15 seconds, permitting safe atrial systole before ventricular systole. This ensures that the ventricles are filled before the ventricles contract.

When the wave of contraction reaches the tip of the ventricles, ventricular contraction begins. As the pressure in the ventricles increases, the AV valves close. This prevents the back flow of melodic phrase. With proceed contraction of the ventricles, blood leaves the heart via the aortic and pulmonary valves into the aorta and pulmonary artery respectively. At the end of the cardiac cycle, all the chambers relax, the aortic and pulmonary valves close, preventing the blood from satiny back into the heart. Atria begin to fill up with...
