Cardiorespiratory variables during a continuous ramp exercise protocol in normal young adults.

Abstract:

:The purpose of the present study was to determine whether the cardiorespiratory variables measured during an exercise test with a continuously increasing workload (ramp) protocol are reproducible and to compare them to the values obtained with a step-wise incremental (James) protocol. Twenty normal adolescents and young adults performed two exercise tests on a cycle-ergometer, one with each protocol, and twelve of these subjects additionally performed a second identical ramp test. The results show that the cardiorespiratory variables measured during exercise with ramp protocol are reproducible and that peak values are not different from those obtained with step-wise incremental exercise protocol, except for a higher peak power. At intermediate equivalent workloads, there were significant correlations between cardiorespiratory variables measured in steady-state conditions with the incremental protocol and those obtained in non-steady-state conditions with the ramp protocol.

  • True left ventricular aneurysm after blunt chest trauma.

    abstract::Left ventricular aneurysms are common in clinical practice. Although their underlying aetiology is generally clear by the clinical context, it can be hard to define the exact cause in some cases. We report a case of a patient in whom cardiac MRI provided important information about the differential diagnosis of a left...
