ECG (Electrocardiography)
Recording of the heart's electrical activity; rhythm and ischemia assessment.
Areas of Expertise
Cardiology Tests in Izmir: ECG, Echocardiography, Holter, Stress Test
Imaging and electrophysiological methods play a fundamental role in the diagnosis of heart and vascular diseases. Prof. Dr. İstemihan Tengiz provides comprehensive evaluation using ECG, echocardiography, Holter monitoring, stress testing and advanced cardiac imaging at Medicana International Izmir Hospital.
ECG (Electrocardiography)
ECG is a painless, rapid test that records the heart's electrical activity. It is used to evaluate heart rhythm, enlargement, past heart attack signs, and electrolyte imbalances. The test takes 5-10 minutes and requires no preparation.
ECG is essential in the initial evaluation of chest pain, palpitations, and shortness of breath. It also serves as a basic indicator of heart health in routine check-ups.
Echocardiography
Echocardiography uses ultrasound waves to visualize the heart. Chamber sizes, wall thickness, valve structure and function, and pumping strength (ejection fraction) are assessed. The procedure is painless, radiation-free, and takes approximately 20-30 minutes.
Stress echocardiography evaluates how the heart performs under exertion. It is preferred when coronary artery disease is suspected but ECG findings are inconclusive.
Holter and Other Rhythm Recording Devices
Holter is a portable ECG device that records heart rhythm continuously for 24 hours during daily life. It is used to evaluate intermittent symptoms such as palpitations, dizziness, or fainting. The patient goes about normal activities while wearing the device.
For less frequent symptoms, 7-14 day extended Holter or event recorders may be used. While some modern smartwatches can perform rhythm recording, medically certified devices are the standard for diagnosis.
Stress Test (TREADMILL)
The stress test evaluates the heart's response to exertion while walking on a treadmill. ECG, blood pressure, and heart rate are continuously monitored. It is used to diagnose coronary artery disease, assess its severity, and evaluate treatment response.
Patients should wear comfortable clothing and avoid heavy meals 2-3 hours before the test. Medications affecting heart rate, such as beta blockers, may need adjustment under medical supervision before testing.
Procedures Performed
Echocardiography
Ultrasound imaging of the heart; valve structure and pump function.
24-Hour Holter ECG
Continuous cardiac rhythm recording during daily activities.

Ambulatory Blood Pressure Monitor
Periodic blood pressure measurement over 24 hours.
Frequently Asked Questions
What is the difference between ECG and echocardiography?
ECG shows the heart's electrical activity while echocardiography reveals structural and mechanical properties. They provide different information and complement each other.
Can I shower while wearing a Holter monitor?
Holter devices are not waterproof. You need to remove it for showering. The removal period is recorded as a gap, which is normal.
How long does a stress test take?
The test usually takes 8-12 minutes, depending on the patient's physical capacity and the purpose of the test.
Do these tests involve radiation?
ECG, echocardiography and Holter involve no radiation. Advanced imaging like coronary CT angiography uses low-dose radiation.
