Exertion Test (Stress test)
Exertion test can be applied in two ways
– Exertion ECG ( Electrocardiography)
– Stress ECO (Echocardiography) (With exertion or medication)
a. Stress ECG test:
Continuous cardiac electrocardiography of the patient suspected of having stenosis of the heart vessels while walking on the treadmill at a fast pace is called 'exertion test'
>b. Stress Echocardiography:
In some special cases, ultrasonographic examination of the heart (ECHO) is taken immediately before and immediately after the exercise test, and the accuracy of the diagnosis of heart disease is increased compared to the normal exercise test. It is made even more increased.
A 4-hour fasting period is required for the effort test. It is beneficial for patients to come with sports shoes and tracksuits, if possible.
Echocardiography and Color Doppler
The structure of the human heart, the diameters of its cavities, the working capacity of the heart muscle and The technique that converts the structure and functions of the heart valves into live images using the sound wave method is called echocardiography (ECHO). No preparation or fasting is required for this test and the entire test can be completed in a short time.
Cardiac Catheterization and Coronary Angiography
The structure of the heart, heart chambers and large It is possible to precisely observe the pressure values in the vessels, stenosis and insufficiency in the heart valves, and especially whether there is narrowing or occlusion in the heart vessels, thanks to cardiac catheterization and coronary angiography. Thanks to this technology, radiological photographs of each of the heart vessels are taken separately from different angles. The procedure time is usually between 10-20 minutes and a 4-6 hour bed rest is required after the procedure. It is performed with the help of a catheter advanced from the groin artery to the heart under local anesthesia. During cardiac catheterization, the pressures inside the heart are measured and at the same time, the contraction function of the heart is examined by injecting 'dyed substance' into the left heart cavity.
Holter Monitor (Heart Rhythm or Blood Pressure Holter)
The heart rhythm is monitored and recorded 24 hours a day with a device called holter. Thanks to this device, heart rhythm disorder can be diagnosed.
Blood pressure holter records the fluctuation of patients' blood pressure 24 hours a day, during the day, under real-life conditions, and blood pressure values during sleep.
Electrophysiologically. Study
It is the most definitive method of diagnosis of heart rhythm disorders. Thanks to this procedure, which is performed with the help of a special catheter advanced from the groin vein to the heart under local anesthesia, the locations of rhythm disorders that cause the heart to work too fast (tachycardic) or too slow (bradycardic) are removed. It is determined by 'millimetric' measurements, and the 'Rhythm Disorder Map' required for definitive treatment is prepared. This method, which requires highly developed knowledge and technology, can be applied in only a few centers in Turkey.
Cardiac MRI
The examination of the cardiac membrane, heart chambers and valves, heart It is an imaging method that reveals the structure of the muscle and large arteries coming out of the heart and some heart diseases (such as narrowing, dilation, calcification) in an extremely easy and non-harmful way to the patient. The procedure time is around 15 minutesand does not require any preliminary preparation.
Nuclear Cardiology
a) Myocardial Perfusion Scintigraphy (Thallium Test): It is a more sensitive method than the exercise test in investigating whether there is any blockage or stenosis in the vessels feeding the heart. Thallium, a radioactive substance administered intravenously, examines the blood flow (or nutrition) of the heart muscle during rest and during exertion. The test must be performed while fasting.
b) MUGA: It is the most accurate method for measuring the pumping power of the left ventricle of the heart. Before the procedure, the red blood cells of the blood are marked with a radioactive substance called Technetium. Imaging
Heart function is measured simultaneously with ECG recording.
