What is the ventricular pressure?
Ventricular pressure is the level of blood pressure in the chambers of the heart. Measured in torre or gravitic pressure of 1 millimeter mercury column at a defined density, the right chamber normally registers up to 30 torr. The left chamber, responsible for drawing blood throughout the body, will usually develop 100-140 torr during its contraction. At rest, both chambers are difficult to register 2-3 torr. When the pressure is constantly measured, not only for the chambers, but for all parts of the heart, the graph becomes a medical diagnostic tool surprisingly high loyalty for heart functioning. Two halls receive blood, the right chamber pumps blood into the lungs and the left ventricle at the same time pumps blood through the massive aorta blood vessel to circulate oxygen and nutrients throughout the body. The term 'heart cycle' is used to describe the sequential contraction of the chambers, open and closure of one -way valves that separate the chambers, as well as their respective incoming or outgoing blood vessels and the resulting flow paths and blood fluid characteristics.
On the increase in the well -known Iambic heart rhythm, several closed valves show that both atriums closed and their contents flowed into the chambers. On Downbeat, about 0.1 seconds later, necessarily strong ventricular pressure from their contraction ejects the contents on the distant part of the body. The task would not be possible without a pulsating effect of the heart - a wave of powered waves created by alternating changes in pressure in blood vessels from systolic contraction of the heart and diastolic relaxation. The same Pressure principle is automatically controlled by the synchronized heart cycle itself in four heart chambers and connecting containers.
Over the years, cardiologists studying hearts have attached sensitive converters to measure the exact pressure of each of its anatomical parts undergoing a normal heart cycle. When it is brought, the X -axis measures the duration of the cycle and the axis of the Y axis, it is clear that, for example, the chamber pressure rises rapidly and the song for ejecting the blood in the systole. Apparently jE also clear that the left ventricular pressure is about 4.7 times larger than its side counterpart, which only needs to pump blood into the nearby lungs to replace respiratory gas. When all graphs are labeled and covered, the resulting graph is called the Wiggers diagram.
Even the view of the Wiggers diagram is medically diagnostic. Crossroads of ventricular pressure and atrial pressure curves - that is, when their respective pressures are equalized - define the exact point where their connecting valves open and close. The aortic graph shows a short pressure drop when its large valve closes shortly after the left ventricular contraction, unable to prevent a small amount of reverse flushing. Other overlaps for diagram, such as electrical signals from electrocardiogram or speed change in the volume of each heart chamber, provide additional diagnostic information.
Due to the known basic line, there are irregularities in the Wiggers diagram indicators of different heart conditions and diseases. Weakened andRegurgitation valves can be identified by "hiccups" in pressure curves or a narrowed blood vessel will have an increased pressure difference with the connected chamber. When considering cardiac surgery, the unusually high diastolic pressure of the left ventricular is considered to be a risk factor. A left ventricular loop that combines two relevant curves overall cardiac efficiency and health of circulation.
