Key result
VEQSI was significantly associated with the presence of structural heart disease (P=0.013), while the number of VEB morphologies independently predicted all-cause mortality (P=0.02).
Why the study?
Does the ventricular ectopic QS interval (VEQSI) or the number of VEB morphologies predict structural heart disease and mortality in patients undergoing Holter monitoring?
Cohort (n=2,332)

p-value: p=0.013
In patients undergoing Holter monitoring, the VEQSI is a marker for structural heart disease, and the number of VEB morphologies is an independent predictor of all-cause mortality.

May support VEQSI and VEB morphology count for risk stratification on Holter; hypothesis-generating pending prospective validation.
Gallagher et al. (2007) conducted a cohort in Patients undergoing Holter ECG monitoring (n=2,332). Ventricular ectopic QS interval (VEQSI) and VEB morphologies was evaluated on Presence of structural heart disease and all-cause mortality (p=0.013). VEQSI was significantly associated with the presence of structural heart disease (P=0.013), while the number of VEB morphologies independently predicted all-cause mortality (P=0.02).
