Figure 2From: Quantification of left atrial strain and strain rate using Cardiovascular Magnetic Resonance myocardial feature tracking: a feasibility studyLeft atrial strain and strain rate profiles. Left atrial function compromises reservoir, conduit and contractile booster pump function. Total strain (εs) and peak positive strain rate (SRs) correspond to reservoir function. Passive strain (εe) and peak early negative strain rate (SRe) correspond to conduit function. Active strain (εa) and peak late negative strain rate (SRa) correspond to contractile booster pump function.Back to article page
