Dyspnea (dyspnoea)Įxercise does lead to tachypnea (increased respiratory rate), which should, however, be distinguished from dyspnea which is shortness of breath. Chest pain rated as 6 or above (according to the 10 point scale) should prompt termination of the stress test (refer to Termination criteria during stress testing). It is important to clarify whether the pain provoked by exercise is similar to the pain that leads to the stress test (if that was the reason for conducting the test). The severity of the pain may be graded from 0 (none) to 10 (maximal pain). Chest pain (chest discomfort)Ĭhest pain during exercise is one of the strongest predictors of coronary artery disease. For example, if the perceived exertion is 12, then 12 x 10 = 120 so the heart rate should be about 120 beats per minute. There is a strong correlation between a person’s perceived exertion rating times 10 and the actual heart rate during exercise so a person’s exertion rating provides an estimate of the actual heart rate. It feels very heavy, and the person is very tired.įor most people this is the most strenuous exercise they have ever experienced. “Somewhat hard” exercise, but it still feels OK to continue.Ī healthy person can still go on, but he or she really has to push him- or herself. Borg Rating of Perceived Exertion Scale RATINGįor a healthy person, 9 is equivalent to walking slowly at his or her own pace for some minutes. Notably, a high perceived exertion at low workload is a strong predictor of adverse outcomes. The Borg scale is well validated at ranges from 6 (none) to 20 (maximal exertion). The perceived exertion may be graded from 0 (none) to 10 (maximal exertion) or according to the Borg scale. Although this is a subjective measure, it provides a fairly good estimate of the actual workload. It is based on the subjective physical sensations experienced during exercise, including increased heart rate, increased respiratory rate and depth, increased sweating, and muscle fatigue. The patient’s perceived exertion is a way of estimating the intensity of the physical activity. Symptom during exercise stress testing Perceived exertion This article will discuss each of these six parameters in detail. ECG reaction: ST changes, T-wave changes, arrhythmias, conduction defects. Heart rate: maximal heart rate, heart rate response.Exercise performance (functional capacity, exercise capacity).However, the ECG is only one of the parameters that must be evaluated and the final result of the test depends on an integrated assessment of six components: Indeed, clinicians often use the term exercise ECG instead of the correct term exercise stress test. The ECG reaction has always been a central component of the exercise stress test. Evaluation of the exercise stress test (exercise ECG)
