What Is Cardiology?

Cardiology is a branch of medicine that deals with the diseases and disorders related to the heart as well as the circulatory system. The branch deals with the diagnosis and treatment of coronary heart diseases, heart failure, valvular heart disease, and congenital heart diseases.

Its sub-specialties include nuclear cardiology, electrocardiography, intervention cardiology, and electrocardiograph. Some of the diseases related to heart are Heart disease, Cardiovascular disease, Atherosclerosis, cardiac arrhythmia, Cardiomyopathy, Hypertension or High Blood Pressure.

The risk factors that lead to heart diseases are high BP, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol. Read the cardiology journal for detailed information.


The Standard Tests For Congenital Heart Diseases Are:

Electrocardiogram (ECG or EKG):

This test is used to measure the electrical activity of a heartbeat to assess for any heart disease.

Chest X-Rays:

An X-ray test is an imaging test that is conducted by using small amounts of radiation to produce images of tissues, organs, and bones of the body. The chest X-ray helps to look for any abnormalities or diseases of bones, heart, airways, blood vessels, and lungs.


It shows the graphic outline of the heart’s movement and is used to assess the overall health or function of the heart.

Cardiac Cauterization and Angiogram:

It is a diagnostic test that takes pictures of blood vessels with the help of X-rays to detect for any blockages in them.

Magnetic Resonating Image (MRI) Scan: 

This scan produces detailed images of the inside of the body by using strong magnetic fields and radio waves. MRI scans are performed for a variety of reasons such as torn ligaments, tumors, etc.

Computerized Tomography (CT) Scan: 

CT scan is used to see the inside of the body by using rotating X-ray machines and computers to produce cross-sectional images of the body.

Trans-esophageal Electrocardiogram (TEE): 

This test is performed to produce detailed pictures of the heart and arteries to and from the heart using high-frequency sound waves or ultrasound.

Some of the tests used for Special Heart Rythm Testing are:

Health Monitor

Event Monitor

Implantable Even Recorder

Trans-telephonic Pacemaker/ICD Transmission

Exercise Stress Testing

Electrocardiography testing

Additional Testing

What Is Gastroenterology?

It is the branch of medicines that focuses on the digestive system and its disorders. They include stomach, esophagus, colon, small intestine, pancreas, rectum, gall bladder, bile ducts, and liver. 

The diseases that are caused in the digestive system or the diseases affecting the gastrointestinal tract are organs from the mouth into anus along the alimentary canal. The diseases that are caused due to abnormalities in the digestive system are gastrointestinal cancers, gastrointestinal bleeding, liver cirrhosis, gallstones, gastroenteritis, inflammatory bowel disease. Read the gastroenterology journal for a detailed study.

The standard diagnostic and therapeutic tests or procedures are:


It is an exam or test that is done to take a look inside the large intestine too look for any rectal bleeding, abdominal pains, or changes in the bowel. Colonoscopy helps to detect any abnormalities in the large intestine.


An endoscopy is a procedure wherein special instruments are used to look inside and operate on the internal vessels and organs of the body without the need to make large incisions in it. The test helps to see for any abnormal symptoms in the digestive system.

Endoscopic Retrograde Electroencephalography (ERCP): 

This test procedure helps diagnose diseases of the liver, pancreas, gall bladder, and billiard system. It helps to see the bile ducts, gall bladder, and the pancreatic ducts on X-rays.

Endoscopic Ultrasound (EUS): 

This test is performed to assess diseases in the lungs as well as the digestive system by using high-frequency sound waves with the help of which detailed images of the walls and lining of the stomach, gastrointestinal tract and chest, liver, pancreas, and lymph nodes are taken. 

The test is used to find out the cause of symptoms such as chest pain or abdominal pain and learn the extent of the diseases in the lungs or the digestive tract. Other tests include liver biopsy, colonoscopy, stool test, barium swallows, and endoscopy.
