EXAMINATIONS


Examinations used for diagnosis of cardiovascular diseases.   

Ekg
It shows the condition of electrical system of the heart, the rate, whether there is arrhythmia or not, whether the patient has had heart attack before or at that moment. The possibility of diagnosing embolism in EKG taken during resting is very low (useful at the rate of lower than 40%). 

EKG unit recording for 24 hours is called “Holter EKG”. Holter EKG is used to investigate arrhythmia time of starting and ending of which is not clear and reasons of syncope. 

Effort Test
If EKG of the patient is normal while resting, whether the disease symptom will be observed in cases that the heart is forced by medicine, running or treadmill or not is revealed. However, the result of this test does not always mean that there is a disease. This is called “Pseudo positivism”. It is frequently seen in the women between the ages of 30-40.  Normal result of the test does not guarantee that there will be no cardiac problem.

Echocardiography
Echocardiography is the ultrasound of the heart. While the heart is functioning, whether there is stenosis or leaking in the valves without pain and blood or not if yes it is significant or not, whether there is hole in the heart or not and conditions of cardiac veins indirectly as the heart strains. In some cases, echocardiography is performed with a special imaging probe (searching for a hole in the heart, clot in the heart or insufficient image with ordinary echo). It is called as transesophageal echocardiography. This examination offers images with higher quality than normal echocardiography.

Scintigraphy
Radiating substances in harmless quantity that will be used by only living heart cells are administered and vitality condition of myocardium and vascular stenosis is understood. This test is directly related to the blood of heart. The heart is forced by exercise or various medications and then radioactive substance will be administered to the blood. If cardiac veins are normal, this substance will reach to the cells in equal time and every side of heart will be stained simultaneously in the images taken. If there is stenosis or occlusion in any one or two of 3 cardiac veins, since this area that the vein feeds will not have sufficient blood and therefore radioactive substance, images taken from this part will be stained late or will not be stained.

Angiography 
Angiography in other name “coronary angiography” is reaching the heart via leg or arm arteries and making the cardiac veins not visible in normal film visible and taking the mobile film. Angio is only an examination and does not mean any intervention for heart. Embolism is certainly identified. 

Coronary Angio Computed Tomography(Multislice Ct, Bloodless Angio)
Opaque substance (this substance makes the vein visible in the image) is administered to the patient with an automatic instrument and serum needle inserted in the arm of the patient in this method different from other methods. Images are made 3 – dimension in computer and assessed. This procedure is carried out with well developed special computed tomography by radiologists. The examination is carried out within time that the patient can hold his breath (approx. 20 seconds). The greatest advantages are not requiring hospitalization and it can be performed at short notice. However, heart rate should not be very fast it should be about 60/min to perform this procedure. Quality of examination diminishes at high heart rates. If a problem is found, coronary angiography may be requested.
