QLAB - Strain Quantification (SQ)

Echocardiographers requested better tools to help assess regional myocardial function, ideally offering quantitative capabilities rather than just new qualitative tools. The Strain Quantification (SQ) plugin is very intuitive and flexible, with customizable settings through the “Preferences” menu. The SQ plug-in has proven successful in many clinical applications, for example: evaluation of regional myocardial function, assessment of synchronicity and guidance during bi-ventricular pacing procedures.

Powerful and flexible, with customizable settings through the “Preferences” menu

• Tissue Doppler Imaging (TDI) velocity mode quantification
• Used in the evaluation of myocardial function and segmental wall analysis
• Measures the myocardial velocity and derives the strain rate and strain along user-defined M-lines
• Capable of drawing up to 4 M-lines at a time
• Point of Interest (POI) tool obtains values from any point on the M-mode display
• Able to present results in two display formats:
  – “Virtual” M-mode display
  – Graph display
• Automatic subdivision of M-line into a customizable number of sub-regions
• Averages up to 20 cardiac cycles in both virtual and graph displays
