Checking the outcome of different stimulation modes - Case study

This 81 year-old Lady was implanted two weeks before the measurement with a bi-ventricular pacemaker to treat her heart failure with resynchronization therapy.

Different stimulation modes have been tested and their outcome in terms of stroke volume has been assessed.

The stoke volume was much better in left ventricular stimulation only (LV) compared to right ventricular stimulation only (RV). Bi-ventricular stimulation leads to intermediate results.
