strain_elsd: Earliest-to-latest segment delay
In dloewenstein/straindys: A collection of tools to calculate different strain and dyssynchrony metrcis for CMR FT
Description
Usage
Arguments
Details
Description
Time delay between earliest and latest contracting left ventricular wall
segments
Usage
1
strain_elsd(data, subset_pattern = NULL)
Arguments
data
Dataframe, columns containing strainvalues from LV wall segments
according to the AHA-17 segment model.
subset_pattern
Regex pattern for subsetting over which columns to perform
analysis.
Details
Non-uniform contraction of the left ventricular wall can be quantified by
means of dyssynchrony analysis. It is known that in case of left bundle branch
block, the septum normally contracts before the lateral free wall. However,
this is not always the case and therefore measureing the delay between earliest
and latest segment, independent of location might better characterize the
pattern of dyssynchrony.
