Electrocardiogram An electrocardiogram (ECG or EKG) tells how the heart is functioning by calculating the electrical activity of the heart. It is a simple, painless test. For each heart beat, a wave or an electrical impulse moves  through the heart. This wave makes the muscle to squeeze and pump blood from the heart. The electrocardiogram is of greatest importance in diagnosing cardiac arrhythmias, acute and prior myocardial infarctions (heart attacks), pericardial disease, and cardiac enlargement (atrial and ventricular).

Pulmonary valve stenosis Pulmonary valve stenosis (pulmonary stenosis) (PS) can be understood as a dynamic or fixed anatomic hinderance to blood flow from the right ventricle (RV) to the pulmonary arterial vasculature, which may cause RV pressure overload that in turn leads to elevated contractility and dilation and results in increased wall stress and compensatory RV hypertrophy.   The pulmonary valve is located between the right ventricle and the pulmonary artery. It has three leaflets that operate like a one-way door, letting blood to move forward into the pulmonary artery, but not backward into the right ventricle. But with pulmonary valve stenosis, problems with the pulmonary valve do make it difficult for the leaflets to open and let blood to flow forward from the right ventricle to the lungs in a usual fashion. In children, these problems can include: A valve that has leaflets that are partially fused together. A valve that has thick leaflets that do not open all the way. The area above or below the pulmonary valve is narrowed https://www.sonseniormedicare.com/pulmonary-valve-stenosis-pulmonic-stenosis/1078/

Tricuspid valve stenosis Tricuspid valve stenosis or tricuspid stenosis refers to narrowing of the tricuspid valve opening. Tricuspid stenosis interferes with blood flow between the upper (atrium) and lower (ventricle) part of the right side of the heart. The tricuspid valve is located between the right atrium (upper chamber of the heart) and right ventricle (lower chamber of the heart) and prevents blood flow from returning into the right atrium from the right ventricle. Its role is to make sure blood flows in a forward direction from the right atrium to the ventricle. Tricuspid valve dysfunction is as a result of morphological alterations in the valve or from functional aberrations of the myocardium. Tricuspid stenosis is almost always rheumatic in origin and is generally accompanied by mitral and aortic valve involvement. https://www.sonseniormedicare.com/tricuspid-valve-stenosis/1069/

Mitral valve stenosis Mitral valve stenosis means blood flow between the chambers on the left side of the heart can’t flow as easily. This condition is almost always the result of an allergic or immune reaction to a bacterial infection, but children can also have this when they're born. It can also happen in the elderly. The mitral valve is a bileaflet valve located between the left atrium and left ventricle. The normal mitral opening area is 4 to 6 square centimeters. In normal physiologic circumstances, the mitral valve opens during left ventricular diastole to let blood to flow from the left atrium to the left ventricle. The pressure in the left atrium and the left ventricle during diastole are the same. The left ventricle is filled with blood during early ventricular diastole. There is only a small volume of blood that stays in the left atrium. With the contraction of the left atrium (the "atrial kick") during late ventricular diastole, this small volume of blood fills the left ventricle. Mitral valve areas less than 2 square centimeters impedes blood flow from the left atrium into the left ventricle. This creates a pressure gradient across the mitral valve. As the gradient across the mitral valve increases, the left ventricle requires the atrial kick to fill with blood. Mitral valve area below 1 square centimeter causes elevates left atrial pressure. The normal left ventricular diastolic pressure is 5 mmHg. A pressure gradient across the mitral valve of 20 mmHg due to severe mitral stenosis may cause a left atrial pressure of about 25 mmHg. This left atrial pressure is transmitted to the pulmonary vasculature resulting in pulmonary hypertension. Check out https://www.sonseniormedicare.com/mitral-valve-stenosis/1057/

Heart auscultation/carfdiac Auscultation Heart auscultation allows for the detection of common holosystolic (mitral regurgitation and ventricular septal defect), systolic ejection (aortic stenosis or hypertrophic cardiomyopathy), and diastolic (aortic insufficiency and mitral stenosis) heart murmurs that can precipitate or exacerbate a decompensation in the ICU or the presence of abnormal heart sounds indicating underlying pathology Heart Auscultation also represents the acquisition of mechanical vibrations from the surface of the body that encompass the frequency range of sound. Vibrations under 20 cycles per second are called “infrasonic,” and although can't be heard, they are normally readily palpable or visible and constitute a source of information supplementing that obtained from the sounds alone. Examples of infrasonic vibrations are brought by precordial motion (thrusts or heaves) and arterial and venous pulses. Check out https://www.sonseniormedicare.com/heart-auscultation/1030/
