Systolic Function and Dysfunction In this paper I will discuss systolic function and systolic dysfunction. I will first define systolic function from physical as well as from physiological aspects: from mechanical and electrical systole, to preload and afterload. From there I will describe four modalities in which systolic function is measured and assessed. This will also include any formulas used to determine needed volumes and percentages. Lastly I will cover three causes of systolic dysfunction. Systolic function in its simplest terms is, how well the ventricle contracts. However, many necessary elements come into play when it comes to fulfilling such a life dependent task.
Definition of Systolic Function To properly define systolic function, you must look at it from all aspects. From the physical to the physiological, and all elements in between. The most basic definition of systolic function is the description of how well the ventricles contract. Mechanical systole, electrical systole and volume systole are three different actions to describe physical systolic function. Mechanical systole is part of the cardiac cycle from when the mitral valve closes to when the aortic valve closes. Electrical systole is described as part of the ECG segment from the onset of the QRS to the end of the T-wave. Volume…
