What is the history of cardiology?

History of cardiology begins in the Renaissance period, with the first precise analysis of the heart role in oxygenation and distribution of blood throughout the body. For three centuries after the doctors slowly developed the means to accurately monitor this vital organ and understanding the disease that could affect it. Only in the middle of the 20th century, however, this technology advanced to the point where surgery became a viable approach to repairing a damaged heart.

points many points to British physician William Harvey for the first real milestone in the history of cardiology in 1628, when he expressed the role of heart drawing with a complex system of living and arteries. Until then, it was assumed that every blood vessel had a natural pulse rhythm and was not recycled. The first exact description of the heart construction took another 80 years, supplied by French biologist Raymond de Vieussens; For the first time, oanatomic mechanics Rgans were able to understand.

over the next two centuries, most of the history of cardiology meant gaining a stronger understanding of heart health and conditions that could affect it. In the 18th century, doctors began to monitor blood pressure to measure organ vitality. At the beginning of the 19th century, doctors could watch the heart rhythm with a stethoscope. The electrocardiograph (ECG or ECG) was invented just after the turn of the 20th century, allowing doctors to analyze the total heart output through electrical impulses. Arterial clogging called arteriosclerosis was first observed about ten years later.

before the 20th century, a scattered surgical first in the history of cardiology occurred. Most of them tried to repair critically injured patients. In 1896, a German doctor named Ludwig Rehn played the first succcessful on an open heart to repair the wound that tore the heart of the soldier. This type of surgery, however, did not normally try until 1953. American John Gibbons inventedl so -called heart pulmonary machine, which allowed the surgeon to keep blood oxygenated and circulate the patient during repair or transplantation.

These repairs were mostly reactive until the dawn of the heart repair operation in 1950, when the successful implantation of artificial aortic valve was carried out by American surgeon Charles Hufnagel. Two years later, another pair of American surgeons used hypothermia to slow down the patient's heart, who successfully underwent a hole repair in her heart. Innovation was intensified with the pacemaker in 1958. In 1967, the first surgery of the coronary artery was carried out - a procedure that was carried out several million times a year in the 21st century. In the same year, the first successful transplantation was South African doctor Christiaan Barnard.

There are many other notes among these many key firstrs in the history of cardiology. Defibrillation was first performed in dogs in 1899. People did not benefit only in 1947, when the machine was used to restore heart functionYoung teens with heart defect. One of the latest milestones took place in 1982, when American cardiologist William Devries implanted the first heart made of artificial tissue.
