✦ Synopsis

We describe a patient who developed the unusual haemodynamic phenomenon of periodic intermittent electromechanical dissociation during regular sinus tachycardia about 20 hours after mitral valve replacement with a tilting disc mechanical prosthesis. Echocardiographic confirmation allowed prompt and life saving corrective surgery for a stuck prosthetic valve disc.

We read with interest the case report by Shah et al. [1]. The authors in this report were not able, however, to provide the echo doppler trace of the prosthetic valve inflow that is diagnostic in this situation. We would like to present a simultaneous electrocardiogram and echo doppler trace from a
