Stress and potential cardiac damage from exercise during the test is a problem in patients with ECG abnormalities at rest or in patients with severe motor disability. Pharmacological stimulation from vasodilators such as dipyridamole or adenosine, or positive chronotropic agents such as dobutamine can be used.
The Bruce exercise test involved walking on a treadmill while the heart was monitored by an electrocardiograph with various electrodes attached to the body. Breathing volumes and respiratory gas exchange were also monitored before, during and after exercise. Because the treadmill speed and inclination could be adjusted, this physical activity ...
Cardiac stress testing is used to determine to assess cardiac function and to disclose evidence of exertion-related cardiac hypoxia. Radionuclide testing using thallium or technetium can be used to demonstrate areas of perfusion abnormalities. With a maximal stress test the level of exercise is increased until the person's heart rate will not ...
Lung disease could be another reason, so doctors may order an echocardiogram and stress test to find out if it’s the heart that’s causing this symptom. Lightheadedness or almost passing out
Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP). It will be a direct indication of the energy demand of the heart and thus a good measure of the energy consumption of the heart.
Angina index is zero if no pain occurs during the exercise, one if the pain is limited to the exercise period but the patient can continue the exercise (typical angina), and two if a pain is a reason to stop the exercise test. [2] [3] Duke treadmill scores typically range from –25 (highest risk) to +15 (lowest risk).
Echocardiogram (heart ultrasound) Angiogram, a scan that shows blood moving through your blood vessels. Blood tests. Blood pressure monitoring. Coronary computed tomography (CT angiogram) Chest X ...
An enlarged heart can be seen at echocardiography or sometimes on a chest X-ray. Similarities at presentation between athlete's heart and clinically relevant cardiac problems may prompt electrocardiography (ECG) and exercise cardiac stress tests. The ECG can detect sinus bradycardia, a resting heart rate of fewer than 60 beats per minute.
