Abstract During the last two decades, radionuclide myocardial perfusion scintigraphy (MPS) has become established as the main noninvasive cardiac imaging technique for the assessment of ischaemic heart disease (IHD). Despite a growing number of alternative imaging techniques, MPS still remains the most widely used technique, with a wealth of literature supporting its usefulness in assessing IHD and predicting prognosis. The technique itself has evolved, making it more reliable and robust, with additional ventricular functional information that further defines the prognosis […]

Abstract The changes presented in the recovery phase of the exercise testing have the same importance as those that occurred during the effort. However, there is no consensus on the ideal protocol to be adopted at this stage. Active or passive recovery have different cut-off points of hemodynamic values and incidence of alterations, as well as changes in relation to the position in orthostasis or supine, caused by neuroendocrine, physiologic or hemodynamic factors. This article aims to explore the physiopathological […]

Abstract The exercise testing has, as most important markers, the ST segment deviation. However, there are also different markers of positivity. The following case report has not shown angina or ST deviations, but has presented alterations in R wave amplitude, Q wave disappearance and T wave pseudonormalization. Has also presented ventricular arrythmias in recovery phase, and depressed behavior of cardiac frequency and systolic blood pres-sure during testing. The test was associated to myocardial scintigraphy, which corroborate the ischemic findings. The […]

Abstract Exercise testing, despite being a widely used method of assessing myocardial ischemia and with known advantages, receives criticism when its accuracy is compared to that of other methods. The use of accessory electrocardiographic signals, in conjunction with the classic changes in the ST segment, is able to improve these indices, improving their reliability in the detection of ischemia. In this article, we will review the unusual manifestations of ischemia in exercise testing, based on the main studies that investigated […]
