Valvular Disease of the Heart-Valvular Heart Murmurs-The Anatomy of Cardiopulmonary Resuscitation

Valvular Disease of the Heart
Inflammation of a valve can cause the edges of the valve cusps to stick together. Later, fibrous thickening occurs, followed by loss of flexibility and shrinkage. Narrowing (stenosis) and valvular incompetence (regurgitation) result, and the heart ceases to function as an efficient pump. In rheumatic disease of the mitral valve, for example, not only do the cusps undergo fibrosis and shrink, but also the chordae tendineae shorten, preventing closure of the cusps during ventricular systole.

Valvular Heart Murmurs
Apart from the sounds of the valves closing, lu¯ b-du˘ p, the blood passes through the normal heart silently. Should the valve orifices become narrowed or the valve cusps distorted and shrunken by disease, however, a rippling effect would be set up, leading to turbulence and vibrations that are heard as heart murmurs.

 
The Anatomy of Cardiopulmonary Resuscitation
Cardiopulmonary resuscitation (CPR), achieved by compression of the chest, was originally believed to succeed because of the compression of the heart between the sternum and the vertebral column. Now it is recognized that the blood flows in CPR because the whole thoracic cage is the pump; the heart functions merely as a conduit for blood. An extrathoracic pressure gradient is created by external chest compressions. The pressure in all chambers and locations within the chest cavity is the same. With compression, blood is forced out of the thoracic cage. The blood preferentially flows out the arterial side of the circulation and back down the venous side because the venous valves in the internal jugular system prevent a useless oscillatory movement. With the release of compression, blood enters the thoracic cage, preferentially down the venous side of the systemic circulation.

  1. My husband was diagnosed with systemic mastocytosis last year and did go to the NIH for  Medical check up .He had already had the bone marrow biopsy and aspiration, as well as the tryptase level test. Basically, they did some blood work there and took extensive medical history from my husband. They told us to go home and our local physician could follow up with him since there are specialist doctors to see locally. We made a research on local herbal medicine and we found out there is a permanent  cure with natural herbs and roots medicine.Of Dr James the great herbal doctor from west Africa, on how he uses his herba mix medicine to cure several diseases like Alzheimer's disease,Lung diseases,Leukemia, Bipolar,Schizophrenia,kidney diseases, Valvular heart,  pulmonary hypertension,  SHINGLES,WARTS,ladder cancerBreast cancerColorectal cancerKidney cancerLeukemiaLung cancerNon-Hodgkin lymphomaProstate cancerSkin cancerUterine cancerParkinson's,Alzheimer’s disease,Bechet’s disease,Crohn’s disease
