How To Enter In The World Of Cardiology Stethoscopes

Stethoscopes are simple yet effective tools that allow doctors to listen to the internal sounds in a patient's body. Doctors can use stethoscopes to listen to a patient's heart, intestines, breathing, and blood flow. It was invented by a French doctor named Rene-Theophile-Hyacinthe Laennec in 1816. Dr. Laennec used a hollow wooden tube to listen to the heartbeat of his female patients so that he wouldn't have to come into improper contact with them by touching his head to their chests. He discovered that it is much easier to hear anomalies with it. He called it stethoscope, after the Greek words for chest (stethos) and the verb to examine (scopeein). The design remained relatively unchanged until the 1940s, when Dr. Sprague and Maurice Rappaport created the basic model that is used today.The cardiology stethoscopes it is used to listen for a variety of irregular sounds that could signal heart problems. Some problems detected by cardiology stethoscopes are irregular heartbeats and heart murmurs. There are a number of different types of cardiology stethoscopes: acoustic stethoscopes,electronic stethoscopes; Acoustic stethoscopes allow doctors to listen to the internal sounds of a patient's body but do not amplify or record the sounds. The electronic stethoscopes can play back recorded sounds at various speeds and even create graphics or charts to visually represent patterns of the sounds. The Advantage of Electronic Stethoscope The Electronic Stethoscope has advanced features such as : Miniature size : Entire electronics is integrated inside a conventional size chest-piece High acoustic sensitivity provides powerful and crystal clear amplification of heart sounds, respiratory sounds and faint murmurs Easy finger-tip graduated volume-control Dual-Frequency diaphragm enables convenient single-sided chest piece operation Electronic Filter to differentiate sounds of variable frequency or pitch Special noise-reduction circuitry to minimize external noises Unbreakable chrome-metal chest-piece High-flexibility polymer tubing with rugged binaural spring Light in weight Feather-soft ear-tips Non-Chill rim for patient comfort. While acoustic stethoscopes may not have all of the same features as electronic models, they are still more common than electronic models and are reliable for detecting irregularities in patient's heartbeat and noticing blood flow problems.
