Recent advances in echocardiography: strain and strain rate imaging
Deformation imaging by echocardiography is a well-established research tool which has been gaining interest from clinical cardiologists since the introduction of speckle tracking. Post-processing of echo images to analyze deformation has become readily available at the fingertips of the user. New parameters such as global longitudinal strain have been shown to provide added diagnostic value, an...

HRV parameters and 6-minute walking test, functional capacity, right ventricular systolic function, BNP and hs-troponin-I levels. Most common cause of death in these patients is arrhythmia, and autonomic dysfunction may be triggering factor (2). HRV parameters are now being used for prognostic evaluation in PAH patients. There are also studies suggesting HRV reduction may be associated with mor...
