During the test, an echocardiography test is done while running on the treadmill. The echo stress test evaluates the functioning of the heart under stress conditions. Its cost ranges from <strong>Rs 3000 to Rs 5000<\/strong> in India.<\/p>\n\n\n\n<p>This procedure determines whether the heart and blood vessels are working properly. This physical examination determines how <strong>efficiently the heart of the patient functions<\/strong> when it <strong>pumps under intense running on the treadmill<\/strong> (TMT).&nbsp;In case of normal stress echo results and problems persist, the Doctor may recommend CT <a href=\"https:\/\/bookmerilab.com\/tests\/ct-scan\/ct-coronary-angiography\/\" target=\"_blank\" rel=\"noreferrer noopener\">Coronary angiography<\/a> for further examination.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What happens during Stress Echo?<\/h2>\n\n\n\n<p>During the stress echo process, a person exercises on a stationary bicycle or a treadmill while the doctor monitors the blood pressure and heart rhythm. An echocardiogram, the ultrasound study of the heart, evaluates the heart\u2019s size, how strongly it pumps, and how well the valves are working.<\/p>\n\n\n\n<p>When the heart rate reaches its peak, the doctor takes ultrasound images of the heart to determine if your heart muscles are getting enough blood and oxygen while you exercise. The Doctor prescribes&nbsp;<strong>a Dobutamine stress echo test<\/strong>&nbsp;to patients who can not perform exercise due to illness or other reasons.&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-procedure-1024x576.jpg\" alt=\"what happens during echo stress testing \" class=\"wp-image-4598\" srcset=\"https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-procedure-1024x576.jpg 1024w, https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-procedure-560x315.jpg 560w, https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-procedure-768x432.jpg 768w, https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-procedure-1536x864.jpg 1536w, https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-procedure-595x335.jpg 595w, https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-procedure.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Monitoring blood pressure while the patient is running on the treadmill followed by heart ultrasound<\/figcaption><\/figure><\/div>\n\n\n<h3 class=\"wp-block-heading\"><strong>Dobutamine Stress Echo Test<\/strong><\/h3>\n\n\n\n<p>The \u2018stress\u2019 is usually triggered by an exercise on a treadmill. However, sometimes, you may not be able to run or exercise. Thus, a medicine, dobutamine helps to induce stress for the test. A doctor will inject the Dobutamine medicine into your veins. This will cause your heart to beat faster thus simulating the effects of an exercise. The rest of the procedure remains the same. <strong>Dobutamine Stress echo test price<\/strong> is usually higher and may cost Rs 1000 to Rs 1500 extra.

This to due to the lower test orders and lack of availability of treadmills, Echo machines and Cardiologists at a diagnostic centres. Usually, the cost starts at Rs 3600. The actual price would depend on the diagnostic centre and city.<\/p>\n\n\n\n<p>The test is available from <strong>21 diagnostic centres<\/strong> in India from Bookmerilab.

The sonographer will put a transducer on your chest to view an outline of the heart\u2019s movement.<\/li>\n\n\n\n<li>After the echo test, the patient exercise on a stationary bicycle or treadmill. The lab personnel will gradually increase the level of exercise. The patient is instructed to continue exercising until exhausted.<\/li>\n\n\n\n<li>Throughout the Stress Echo test, Patient monitoring will be performed. If a problem occurs, then the expert will immediately discontinue the test.<\/li>\n\n\n\n<li>Echocardiogram images will be recorded at different times throughout and after the exercise. A cardiologist will review the images and provide a specialist opinion, and a report shall be sent to the patient\u2019s doctors for treatment.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-gallery aligncenter has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"491\" height=\"346\" data-id=\"4605\" src=\"https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-equipments.jpg\" alt=\"\" class=\"wp-image-4605\" srcset=\"https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-equipments.jpg 491w, https:\/\/bookmerilab.com\/tests\/wp-content\/uploads\/2022\/12\/stress-echo-testing-equipments-447x315.jpg 447w\" sizes=\"(max-width: 491px) 100vw, 491px\" \/><\/figure>\n<figcaption class=\"blocks-gallery-caption wp-element-caption\">Pic Credit: Newcastle Heart<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Stress Echo Timings<\/h3>\n\n\n\n<p>The duration of the appointment is approximately 60 minutes.
