No results posted yet for this study

Summary

Approximately 40% of resynchronization therapy recipients do not appear to clearly benefit. These patients are termed 'non-responders'. This study will assess whether a heart ultrasound (echo) technique called 'torsion imaging' can be used to increase the likelihood of benefit from resynchronization therapy.

Conditions

Interventions

OTHER
