"Treating heart disease starts with an accurate diagnosis and these diagnostic tests include Cardiac Catheterization, or Coronary Angiogram, Cardiac CT Scan , Cardiac MRI ,Chest X-ray, Echocardiogram, Electrocardiogram, Heart Monitoring, Electrophysiology Study, Nuclear Stress Test, Oximetry etc. The test a patient needs to diagnose depends on what condition the doctor thinks he/she may have. A physical exam, personal and family medical history can help shed some light onto if you have heart disease. But apart from simple blood tests to look for high cholesterol and factors, cardiologist may recommend some additional tests to diagnose coronary artery disease. As for diagnosing arrhythmias, the process is complex and intricate. It requires special expertise, unique testing equipment and often monitoring over a period of time. This is because many arrhythmias can come and go, making it difficult to capture an event in any single test. Cardiac Catheterization or Coronary Angiogram A catheter is a flexible tube that a physician guides through an artery from the groin to the heart. To view blood flow through the heart, the doctor injects a special dye into the arteries via the catheter that outlines any possible obstruction. A serial X-ray image is obtained (15 frames per second) to record the blood flow through the coronary arteries and show how the heart pumps blood; seeing these images occur in real-time helps the doctor find where problems occur. This procedure is known as an angiogram, or a coronary angiogram. Doing it via catheter is called cardiac catheterization. These images are stored electronically to be used later by physicians. Cardiac CT (Computerized Tomography) Scan Collects images of the heart and chest used to check for heart failure or arrhythmias. In a cardiac CT, you lie on a table inside a doughnut-shaped machine. An X-ray tube inside the machine rotates around the body and collects images of the heart and chest. A dual-source CT scanner detects artery blockages in the entire body with extreme accuracy. The scanner utilizes imaging dye injected into the arm, and thus does not need placement of a catheter into the heart. This procedure uses MRI technology, often combined with an injected contrast dye, to check for areas of narrowing or blockages. In a cardiac MRI, you lie on a table inside a long tube-like machine that produces a magnetic field. The signals from the magnet create images of the heart that can help the doctor determine the location of blockages or the cause of the heart arrhythmia. International Journal of Cardiovascular Research emerges as a best indexed journal with impact factor compared to other competitive journals focusing on Cardiology tests by bringing up the recent research to global scientific community through its publications. The papers submitted are undergone through perfect plagiarism checks, later peer reviewed by the expert group and published after through revisions. "
