PHYSICAL EXAMINATION. Severe valvular dysfunction, especially aortic stenosis, is an absolute contraindication to exercise stress testing. 4,7 Gallop rhythms are noteworthy because the presence of an S 3 may indicate significant congestive heart failure, a contraindication if it is clinically severe.
What are the contraindications to exercise stress testing?
Determine degree of disability. Although exercise stress testing is a safe procedure, the risk of complications calls for careful consideration of contraindications. Contraindications may be absolute or relative. Briefly, exercise stress testing must not be performed in the presence of absolute contraindication.
Which stress test should be used in patients with normal ECG?
For risk assessment, the exercise test should be the standard initial mode of stress testing used in patients with a normal ECG who are not taking digoxin.
Should patients with submaximal exercise undergo pharmacological stress testing?
Patients likely to exercise submaximally should undergo pharmacological stress testing. Concern about false-positive ST-segment responses may be addressed by careful assessment of post-test probability and selective use of stress imaging tests before proceeding to angiography.
What are the contraindications to exercise testing for unstable angina?
Contraindications to Exercise Testing 1 Appropriate timing of testing depends on level of risk of unstable angina, as defined by the Agency for Health Care Policy and Research Unstable Angina Guidelines. 2 Relative contraindications can be superseded if the benefits of exercise outweigh the risks.

Who is not a candidate for a stress test?
Exercise stress testing should not be performed in patients with symptoms of anemia or severe hepatic, renal or metabolic disorders. A resting ECG is an essential part of the pretest evaluation. The patient should have a resting ECG that is free of the abnormalities listed in Table 4.
When should you not have a stress test?
Usually, you do not need these tests if you do not have any symptoms. The tests are not useful for people who do not have symptoms of heart disease, like chest pain. Yet, many people with no symptoms have an EKG as part of their routine checkups. For example, 1,200 adults between the ages of 40 and 60 were surveyed.

When should an exercise test be stopped?
An exercise test should end when diagnostic criteria have been reached or when the patient's symptoms and signs dictate. After the exercise has stopped, recording continues for up to 15 minutes. ST segment changes (or arrhythmias) may occur during the recovery period that were not apparent during exercise.
What are the contraindications of ECG?
There are no absolute contraindications for an electrocardiogram. The relative contraindications to its use include: Patient refusal. Allergy to the adhesive used to affix the leads.
What is exercise testing?
Exercise testing is widely available and relatively low in cost. For the purposes of these guidelines, exercise testing is a cardiovascular stress test using treadmill or bicycle exercise and electrocardiographic and blood pressure monitoring. Pharmacological stress testing and imaging modalities (radionuclide imaging, echocardiography) are beyond the scope of these guidelines.
Why is pharmacological stress testing more often required in the elderly?
Pharmacological stress testing is more often required in the elderly because of their inability to exercise adequately. Interpretation of exercise tests in the elderly differs somewhat from that in younger patients. Resting ECG abnormalities may compromise the accuracy of diagnostic data from the ECG.
What is the purpose of a heart evaluation?
1. Evaluation of exercise capacity in children or adolescents with congenital heart disease, those who have had surgery for congenital heart disease, and children who have acquired valvular or myocardial disease. 2. Evaluation of the rare child with a description of anginal chest pain.
Why do you need exercise after bypass surgery?
After coronary artery bypass surgery, exercise testing may be used in symptomatic patients to distinguish between cardiac and noncardiac causes of recurrent chest pain , which is often atypical after surgery. If a management decision is to be based on the presence of ischemia, the exercise ECG may suffice.
Is exercise required for valvular disease?
In symptomatic patients with documented valvular disease, the course of treatment is usually clear and exercise testing is not required. However, the expanding use of Doppler echocardiography has greatly increased the number of asymptomatic patients with well-defined valvular abnormalities. The primary value of exercise testing in valvular heart disease is to objectively assess atypical symptoms, exercise capacity, and extent of disability, all of which may have implications for clinical decision making. This is particularly important in the elderly, who may not have symptoms because of their limited activity. Use of the exercise ECG for diagnosis of CAD in these situations is limited by false-positive responses due to LVH and baseline ECG changes.
What is exercise capacity evaluation?
1. Evaluation of exercise capacity and response to therapy in patients with heart failure who are being considered for heart transplantation. 2. Assistance in differentiating cardiac versus pulmonary limitations as a cause of exercise-induced dyspnea or impaired exercise capacity when the cause is uncertain.
Is exercise ECG accurate?
The exercise ECG is commonly viewed as less specific in women than in men, although careful review of the published data shows that this finding has certainly not been uniform. Studies that demonstrated lower specificity in women have cited lower disease prevalence, non-Bayesian factors, and possible hormonal differences. Physicians need to be cognizant of the decrease in sensitivity that occurs when women do not exercise to maximum aerobic capacity. Patients likely to exercise submaximally should undergo pharmacological stress testing. Concern about false-positive ST-segment responses may be addressed by careful assessment of post-test probability and selective use of stress imaging tests before proceeding to angiography. The difficulties posed by clinical evaluation of women for possible CAD have led to speculation that stress imaging approaches may be an efficient initial alternative to the exercise ECG in women. Although the optimal strategy for circumventing false-positive test results for diagnosis of CAD in women remains to be defined, the data are insufficient to justify routine stress imaging tests as the initial test for diagnosis of CAD in women.
What is treadmill stress testing?
Exercise testing is a form of cardiovascular stress testing that uses exercise with electrocardiography (ECG) and blood pressure monitoring. This form of stress testing is usually performed with exercise protocols using either a treadmill or bicycle.
Where is stress testing performed?
Exercise stress testing is performed in a designated lab, supervised by a trained healthcare personnel. Electrodes are placed on the chest, which is attached to an ECG machine that is recording the electrical activity of the heart. Your resting ECG, heart rate, and blood pressure are obtained prior to starting the exercise regimen.
What are the symptoms of treadmill testing?
Indications for treadmill testing include: 1 Symptoms suggesting myocardial ischemia 2 Acute chest pain in patients excluded for acute coronary syndrome (ACS) 3 Recent ACS treated without coronary angiography or incomplete revascularization 4 Known CAD with worsening symptoms 5 Prior coronary revascularization (patients 5 years or longer after Coronary artery bypass grafting [CABG] or 2 years or less after percutaneous coronary intervention [PCI]) 6 Valvular heart disease (to assess exercise capacity and need for surgical intervention) 7 Certain cardiac arrhythmias to assess chronotropic competence 8 Newly diagnosed heart failure or cardiomyopathy[1][4]
What are baseline ECG changes?
Such baseline changes include ST-segment changes that are greater than or equal to 1 mm, left bundle branch block, ventricular paced rhythm, left ventricular or right ventricular hypertrophy, ventricular pre-excitation (i.e., WPW syndrome), T wave inversions due to strain pattern or previous injury, conduction abnormalities and medication-induced ST-T wave changes. If any of these ECG abnormalities are noted, the test should be performed with the addition of an imaging modality. The resting ECG is usually obtained both supine and standing, since patient position can influence the QRS and T wave axes.
How long should you not smoke before a blood test?
Patients should be instructed not to eat, drink, or smoke for at least three hours before the examination, as this allows for maximal exercise capacity. The patient should bring comfortable exercise clothing and walking shoes to the testing facility. The healthcare professional perming the test should explain benefits the risks, benefits and possible complications to the patient before testing and patient is given an informed consent form to review and sign.
Does exercise cause blood flow?
Exercise is associated with sympathetic stimulation and changes in coronary vasomotor tone which affects coronary blood flow. Several studies have reported that the coronaries dilate during exercise. Some reported mechanisms that may contribute to this dilatation include the release of vasoactive substances from the endothelium due to increased myocardial oxygen consumption, passive relaxation due to the increase in coronary arterial pressure and endothelium-mediated limitation of constrictor effects of catecholamine.
Is exercise stress testing safe?
Exercise stress testing is generally safe. Complications are rare, and the frequency of serious adverse cardiac events (i.e., myocardial infarction, sustained ventricular arrhythmia, and death) has been estimated to be approximately 1 in 10,000 patients.
What is the purpose of stress test?
A physician may recommend an exercise stress test to: Diagnose coronary artery disease. Diagnose a possible heart-related cause of symptoms such as chest pain, shortness of breath or lightheadedness. Determine a safe level of exercise.
What test is used to predict heart attack risk?
Depending on the results of the exercise stress test, the physician may recommend more tests such as a nuclear stress test or cardiac catheterization.
What are the things that are monitored during an EKG?
