Acute, Exercise Dose-Dependent Impairment in Atrial Performance During an Endurance Race

Abstract

During a trail-running race, an acute exercise-dose dependent impairment in atrial function was observed, mostly in the RA, which was related to RV systolic dysfunction. The impact on atrial function of long-term endurance training might lead to atrial remodeling, favoring arrhythmia development.

The impact of volume overload on right heart function in end‐stage renal disease patients on hemodialysis

“…Assessment of RA with 2D speckle tracking echocardiography can provide more information on RA physio‐mechanics without the need of interventional methods. Most of the studies evaluating the RA by 2D speckle tracking echocardiography were only performed in healthy populations; however, the assessment of pathological conditions is needed . Depending on the methods used by the researchers, it is necessary to carefully examine the data they describe.…”

“…They should provide information on how they obtained their strain measurements. The proper definition of end‐diastole on the electrocardiogram and the proper identification of LS of RA phases should be clearly described to have consistency in the literature . Thus, new technological improvements can be used for physio‐mechanic assessment of the RV and RA in a standardized manner.…”

“…Also, the lack of reproducible and load‐independent methods raise difficulties while assessing RV function and its relation to the RA . 2D speckle tracking strain analysis, a recent development in echocardiography, might provide more consistent results and information on the functional status and physio‐mechanics of RV and RA …”

“…3,9,14 2D speckle tracking strain analysis, a recent development in echocardiography, might provide more consistent results and information on the functional status and physiomechanics of RV and RA. [15][16][17][18][19][20][21][22][23] We have therefore planned a study to evaluate the effect of volume depletion on RV and RA physiology and attempted to determine the echocardiographic parameters, which are not affected by volume changes by examining end-stage kidney patients immediately before and after hemodialysis (HD) since HD provides a rapid and considerable volume change in a short time.…”

Evaluation of Left Atrial Functions by 2‐dimensional Speckle‐Tracking Echocardiography During Healthy Pregnancy

“…New echocardiographic parameters such as strain and the strain rate (SR) are closely related to the functional state of the LA and more sensitive in the early detection of its subtle changes . Strain and the SR represent the magnitude and rate of myocardial deformation .…”
