Journal of the Hong Kong College of Cardiology
Conventional cardiac activation mapping requires a sequentially-based method of positioning a catheter in contact with the endocardium to generate intracardiac electrograms at single points during sustained arrhythmia. Significant limitation of such point by point mapping may be encountered when applying to complex arrhythmia e.g. non-sustained arrhythmia or haemodynamically unstable arrhythmia. A novel non-contact mapping system (Ensite 3000 system) providing a three-dimensional simultaneous display of arrhythmia activation may offer a solution. The non-contact mapping system consists of a specially designed balloon catheter (Ensite EP catheter) with 64 insulated wires over the surface of the balloon for sensing electrical potentials on the …
