From: Left ventricular dyssynchrony can be observed via cine CMR with use of aortic valve timing
End-systolic dyssnchrony was quantified in 67 patients with a range of EF and QRS durations. Observed values were classified based on high, mid and low ED as well as normal prolonged QRS duration. The observed dyssncrony for patients with low EF and prolonged QRS is higher than all other groups. However, more patients are necessary to achieve signifance.
