title: Optimization of biventricular pacing via strain dyssynchrony measurements in a paediatric patient.
abstract: Cardiac resynchronization therapy is increasingly being used in the paediatric population as a tool for managing patients with heart failure. Various non-invasive parameters have been used to optimize the settings on the biventricular pacemaker. We describe implantation of a biventricular pacemaker in a nineteen-month-old child because of intractable heart failure. By analysing a 17-segment model using strain analysis of the left ventricle, we were able to place the left ventricular lead at the latest activated segment. Furthermore, we were able to minimize the dyssynchrony of the left ventricle when evaluating a range of pacemaker settings.
