In Acute Right Ventricular Failure, What are the Effects of Preload and Afterload?Keywords acute right ventricular failurepreloadafterloadpulmonary embolismright ventricular infarctpulmonary hypertensionThe right ventricle (RV) differs from the left ven...
Before congenital heart surgery is undertaken, the assessment of left ventricular contractility, preload, and afterload is important for preoperative planning to obtain satisfactory clinical outcomes. Afterload is left ventricular wall stress during systole. Wall stress results from the interaction of pressur...
What is an ECG or an EKG? What is ventricular preload? What is atrial diastole, and what is ventricular diastole? How do these alternate in the cardiac cycle? What medications may cause PVCs to develop? Describe the seriousness and consequences of atrial fibrillation. ...
List and briefly explain the 3 factors that affect SV: preload, contractility and afterload. Explain the significance of safranin in Gram staining. Why is the flat portion of the oxyhemoglobin dissociation curve clinically significant? Describe the importance of the EJC complexes for the ...
Intrinsic forces refer to contractility of lymphatic smooth muscle cells. Lymphatic smooth muscle cells have characteristics of both smooth muscle and cardiac muscle cells which demonstrate spontaneous contractions and contractile forces that are modulated by preload, afterload, and contractility. In concert...
Lymphatic smooth muscle cells have characteristics of both smooth muscle and cardiac muscle cells which demonstrate spontaneous contractions and contractile forces that are modulated by preload, afterload, and contractility. In concert with uni-directional valves, intrinsic lymphatic pumping (rate and ...
The heart is a muscular organ located on the left side of the human chest. It is comprised of four chambers which are separated from each other by valves.Answer and Explanation: The heart pumps blood throughout the body. The muscles of the heart contract rhythmically and these contractions ...
the factors causing an increase in contractility in the heart work by causing an increase in intracellular calcium ions during contraction. Under one existing model, the five factors of contractile myocardium performance are considered to be heart rate, conduction velocity, preload, afterload, co...
