Abstract:
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.
