Cardiology And The Heart
In simple term, cardiology is a field of medicine that concerns itself with disorders of the human heart. The field specializes on diagnosis, treatment and management of coronary artery disease, congenital heart defects, heart failure, electrophysiology and valvular heart disease. Cardiologists are medical professions who specialize in this filed. However, they are not the same as cardiovascular, cardiothoracic and cardiac surgeons who carry out surgery through sternotomy, which are open operative processes on the great vessels and the heart. The heart being the center of focus of cardiology, has a number of anatomical features such as ventricles, atria, heart valves, and various physiological features such as after load, heart sounds and systole.
The heart’s primary task is to pump blood in the body. This means that the human heart is linked to many parts of the body, any of which is vulnerable in case a patient has a serious heart disease. Whilst plenty is known concerning a healthy heart, the mass of the study in cardiology focuses on the disorders and restoration of the heart, where achievable, and of function. The heart is basically a muscle that compresses blood and works like a pump. Every part of the heart is liable to dysfunction or failure and the heart can be separated into the electrical and mechanical.
The electrical element of the heart is rooted on the periodic reduction or squeezing of the cells of the muscle that is brought about by the cardiac pacemaker positioned in the sinoatrial nodule. The examination of the electrical facets is a sub-field of electrophysiology known as cardiac electrophysiology and is characterized with the electrocardiogram ECG/EKG. The potentials of the action generated in the pacemaker circulate throughout the heart in a precise pattern and the structure that transmits this potential is known the electrical conduction system. Disorders of the electrical system manifest in numerous ways and include heart block, ventricular fibrillation and the Wolff–Parkinson–White syndrome.
The mechanical element of the heart is based on the blood’s fluidic movement and the heart’s functionality as a pump. The mechanical element is ultimately the function of the heart and numerous of the dysfunctions of the heart upset the aptitude to move blood. If the heart fails to move sufficient blood, it can result in the failure of other organs and may cause even death if relentless. Heart failure is one situation in which the mechanical characteristics of the heart have failed or are in the process of failing, and this means there is inadequate circulation of blood.
There are other heart disorders that disrupt or affect both the mechanical and electrical properties of the human heart. A more distressing disorder is that of a heart attack also known as myocardial infarction. A heart attack causes cellular loss of the heart which decreases both the mechanical and electrical capabilities of the heart and can cause death if severe. Cardiology is concerns itself with the normal functions of the heart and the divergence from a healthy heart. Numerous disorders involve the heart itself but a number of them are external.
