Subject area	Medicine
More specific subject area	Cardiac imaging
Type of data	Table, graph
How data was acquired	Feature tracking cardiac magnetic resonance (FT-CMR) was used to assess right atrial (RA) and right ventricular (RV) strain and strain rate using commercially available cvi42 software (version 5.3.4, Circle Vascular Imaging, Canada)
Data format	Analysed data presented
Experimental factors	This cohort of 100 healthy subjects was constructed to contain 10 males and 10 females from each decade of life between the ages of 20 and 70.
Experimental features	The endo- and epicardial boundaries of the RA and RV within anonymized CMR studies were defined by observer 1 using cvi42 software. To generate reference ranges, peak longitudinal strain and strain rates were obtained for the RV; peak longitudinal strain rate was obtained for the RA. Observer 1 repeated analyses following 1 months for intra-observer variability. Observer 2 performed blinded analyses for inter-observer variability assessment.
Data source location	University Hospital Birmingham NHS Foundation Trust, UK
