A case of grade 2 A-V block, then changing to complete A-V block, is presented. Observations dealing with the phonocardiographic and electrocardiographic changes are reported. It was noted that there was an abbreviation of mechanical systole and a prolongation of electric systole leading to ‘electromechanical dissociation’. This persisted even after implantation of a transvenous demand pacemaker. As the blood electrolytes always remained within normal limits, the abnormality is attributed to latent heart failure. A review of 10 other cases of A-V block revealed 2 cases with a similar electro-mechanical dissociation.
