Brief Answer: Heart rate return to normal.Abnormal Rhythm& ECG. Detailed Answer: Hello, I have gone through your query and understand your concern. After the Stress ECG test you will be asked to walk or pedal slowly for a couple of minutes to cool down. Your heart rate, blood pressure and ECG will continue to be monitored until the levels begin returning to normal. The desired length of exercise is based upon 1. a target heart rate (determined by the treating doctor based on your age and physical condition) and your own exercise tolerance. 2. You develop chest pain or a change in your blood pressure that is concerning 3. ECG changes show that your heart muscle is not getting enough oxygen 4. You are too tired or have other symptoms, such as leg pain, that keep you from continuing Your exercise duration is an important factor in the stress test result. The test may be stopped if you develop severe symptoms, such as chest pain, dizziness, nausea, severe shortness of breath, severe fatigue, or elevated blood pressure. You will be monitored for 10 - 15 minutes after exercising, or until your heart rate returns to baseline. The total time of the test is around 60 minutes. The meaning of your test results depends on the reason for the test, your age, and your history of heart and other medical problems. It may be hard to interpret the results of an exercise-only stress test in some patients. Abnormal results may be due to: 1. Abnormal heart rhythms during exercise 2. Changes in your ECG that may mean there is a blockage in the arteries that supply your heart (coronary artery disease) When you have an abnormal exercise stress test, you may have other tests performed on your heart: 1. Coronary angiography 2. Nuclear stress test 3. Stress echocardiography. Hope this helps. Please write back for further queries. Wishing you good health.

Brief Answer: Heart rate recovery.Not be less than 12 in 1st min Detailed Answer: Hello, Thanks for your reply query. What you are inquiring is nothing but a Heart rate recovery after stress testing. It is an important predictor of heart disease risk. Your heart rate should drop dramatically during the first minute after exercise and gradually afterward and come to base level after 30 minutes or more. It do not decrease to a point and then increase afterwards provided the complete peaceful rest after exercise stress test. It it is so, then you either go for further investigations which i mentioned above or repeat Stress test after some time. If your heart rate decreases 20 beats per minute (bpm) or more within 1 minute post exercise you are doing well. Here's an example: Your heart rate during the activity reaches 170 bpm. Within in 1 minute post exercise your heart rate should be down to 150 bpm or less. At 5 minutes post workout you should be 120 bpm or less. Heart rate recovery is a measurement of how much the heart rate falls during the first minute after peak exercise. People with an abnormal heart rate recovery, which consists of a score or decrease of 12 or less beats per minute, were at a greater risk for death from heart disease than those with normal heart rate recovery, which is a decrease of 15 to 25 beats per minute. Hope this helps. Please write back for further queries. Wishing you good health.
