Abstract

Despite established selection criteria, 30 to 40% of patients do not respond to cardiac resynchronisation therapy. By optimising programming of the device response to cardiac resynchronisation, therapy can be improved. (Neth Heart J 2009;17:354-7.).

Measurement of the septal to lateral delay, a dyssynchrony measurement to determine intra-ventricular dyssynchrony. Time difference between the maximal myocardial velocity septal (yellow curve) and lateral wall (blue curve) represents the septal to lateral delay.

A: Biventricular pacing during a heart rate of 120 beats/min. B: Recurrence of left bundle branch block conduction during exercise at the moment the heart rate exceeds the upper rate (here a heart rate of 145 beats/min is present, while the upper rate was set at 130 beats/min). Pacing spikes are no longer present.
