Test for heart diseases- Chest X-ray - Electrocardiography or ECG - Exercise electrocardiography - Doppler ultrasound

INVESTIGATIONS  FOR HEART DISEASE .


There are lot of diagnostic tests and procedures currently available to help doctors determine if you have heart disease or vascular disease. If you already have the disease, helping doctors to determine the progress of the disease. Most studies also show images of heart, but only a doctor can say what they show. Some tests are more reliable than others, but only a doctor could tell you where to take based on your symptoms and medical history.

CHEST X - RAY .

Radiation of the chest radiograph in the body means even if the level is minimal. A pregnant woman should take special measures of protection and the fetus. The chest radiograph provides inforamtion on the Size and configuration of the heart and great vessels and lung fields and blood vessels. It is a routine procedure of investigation of radiation exposure very low heart.


ELECTROCARDIOGRAPHY OR ECG .

This test is most common, which virtually all patients who saw a doctor for a heart. heart's electrical activity is recorded at various points in the chest and printed on what is called a twelve lead ECG. A variety of changes you can see that reflected a wide range of heart problems, however, the issue may be quite normal, although there is underlying heart disease.

An electrocardiogram records the electrical activity of a patient's heart. An ECG may be performed to diagnose an acute myocardial infarction (heart attack) and / or detect an abnormal heart rhythm of a patient or pace. The ECG can also provide information on the problems of circulation of blood and oxygen to the heart muscle. Electrodes are placed on the chest and attached to a monitor. The ECG technician will get the best possible reading and files a copy for your doctor to interpret. The technicians are experienced in ECG interpretation for the physician can be notified immediately if there are severe abnormalities or acute changes in the ECG.

For your heart, an electrical pulse is sent from the sinoatrial (SA node), located into your heart. SA node helps your heart keep a steady rhythm. Electrocardiogram can follow the path of the electric power that is sent from the SA node and your heart. This allows the doctor to know if you have a problem which can cause your heart beat unevenly. Small metal discs called electrodes placed on the skin. The electrodes are used to pick up electrical impulses in the heart. The pulses are recorded, allowing doctors a recording of the heart's electrical activity.


EXERCISE ELECTROCARDIOGRAPHY .

This assay is commonly used to discover if the patient has significant coronary artery disease. Twelve ECG apply and are labeled in use until the patient's symptoms, it seems the end, & says the doctor, or changes in ECG. The test can also assess the risk of further difficulties when patients have had a heart attack and assess the degree of certainty, heart failure or breathlessness. Even if the test can not completely exclude heart disease, normal fitness test is unlikely to occur in patients with severe underlying diseases, coronary artery disease.


DOPPLER ULTRASOUND .

Doppler is a test that uses sound waves to examine blood flow to the heart. This test can also help the doctor to see if your heart valves are blocked or leaking blood. Ultrasound can also be abnormal tissues (such as tumors or blood clot) and measure the size of certain organs. Doppler ultrasound uses sound waves at high densities, which are through the body. Sound waves transmitted through a wand-like device called a transducer. When the sensor in the skin tissues of the body, particularly blood, absorb sound waves. The absorption of sound waves from the echoes that are sent to the transducer and converted to a television.

No special preparation is required before an echocardiogram. During the test, you will lie on an examining table. A gel will be put on your thick skin on the area to examine. The gel may be cold, but it does not harm the skin. An ultrasound technician then place the transducer on the skin. The transducer sends and receives sound waves at high frequency. Sound waves to the transducer as echoes that are converted into images on a television screen. These images are recorded and given to a radiologist for reading. An ultrasound takes about 45 minutes to complete. You should have any discomfort, but you can be asked to hold their breath several times during the test. The ultrasound test is a very safe and there are no harmful side effects. In fact the amount of energy used in the sample is so small that it can not cause damage to body tissues ..... Read more
