Cardiology's beginning and William Harvey

# data[].attributes.body
Cardiology first began in the late 1657 when a German doctor, William Harvey, published his studies of the anatomy of the heart and its complicated systems.

René Laennec and the very first stethoscope

In the 18th century, there were several advancements in heart health including the pulse and blood pressure monitor and the stethoscope, invented by a French physician René Laennec.

In 1895, a German physicist's research covered the radiography of the heart, including the x-ray. In 1903, Dutch physiologist, Willem Einthoven, invented Electrocardiography, taking electric currents and checking the heart for irregularities.

In 1929, Cardiac catheterization was invented by a German surgeon, Werner Forssmann, and refined by two American physician and physiologists, André Frédéric Cournand and Dickinson W. Richards, and it greatly opened the direct visualization to systems of the heart. Echocardiography, the use of sound waves to see how blood flows, was later invented in 1950 and is something we still use today.

Open heart surgeries began being performed originally on animals in 1949. In 1953 Dr. John Lewis performed the 1st successful open-heart surgery on a 5-year-old girl. The heart-lung machine was introduced later that same year and was a major contributor to the performance of open-heart surgery. With the same machine, direct vision repair was introduced to perform cardiac valve replacements.

The very first use of the defibrillator was in 1775 but was later researched more thoroughly in 1899. 20 years later, a doctor referred to as Beck was the first to use the defibrillator, directly applied to the heart, in an operating room. Later in 1956, Paul Zoll and his coworkers performed the first successful external defibrillation on a human body.

After Swedish research showed plans for a miniature pulse monitor, the U.S. devised a plan to make an implantable version. In 1958, the 1st pacemaker was implanted and said to have an accurate recording of the heart rate.

In the early 1960s, CCUs, or coronary care units were established to specialized in the intensive care of those with acute myocardial infarctions or severe and often occurring heart attacks. These units are similar to ICUs but for those with heart issues rather than all life-threatening conditions.

A German physician, performed the first balloon angioplasty on a coronary artery. This made a major contribution to the treatment of blocked arteries and restore normal blood flow to live everyday life.

This device was invented to lessen the risk of heart failure for those with leaky valves. These patients were at too high of a risk to have open heart surgery. The Mitraclip was inserted into the allowed the leaking valve to open and close properly.

The first leadless pacemaker was a tiny unit, self-contained and able to fit on the inside wall of the heart as it was very thin and easy to apply.

Good Job! I liked how there was enough information but not too much that it gets boring.
