Moreover, no study has used thoracic impedance to assess CO during supramaximal exercise.
The primary aim of this study was to elucidate the potential of thoracic impedance to estimate SV and CO during the Wingate test, which is unknown, and to compare these responses to those obtained from graded exercise testing, which should elicit maximal values for these variables.
[sup][22] The cardiac hemodynamic status is measured on the basis of changes in systolic and diastolic thoracic impedance. [sup][9] The ICG enables the diagnosis of heart failure and assesses the severity of coronary artery disease [sup][23] to evaluate the efficacy of drug treatment and prognosis.
This is because some monitoring devices measure the same parameter as do the pacemakers (change in thoracic impedance).
Lumax 740 devices contain BIOTRONIK's TI feature, which measures thoracic impedance. The patient's physician can use this information as additional insight to manage critically important aspects of patient care, including drugs used to adjust fluid levels.
