Q. Find the Modalities in stress testing?
In addition to electrocardiographic stress testing, there are various newer modalities that can be very useful in the determination of disability. However, the physician performing and interpreting such test should have the appropriate training and experience. Stress testing done in conjunction with thallium-201 is a more sensitive tool in the diagnosis of coronary artery disease. Its sensitivity has been reported to range from 68 per cent to 96 per cent (average 84 per cent), compared with a sensitivity of 60 per cent to 70 per cent for exercise ECG alone. The specificity of thallium scintigraphy has been reported to be between 65 per cent and 100 per cent (average 87 per cent), which represents a modest improvement compared with the specificity of exercise ECG alone.
