SCA may be associated with transient transmural myocardial ischemia and aborted sudden death in the absence of coronary atherosclerosis. The availability and sophistication of MSCT facilitates the delineation of the course of a SCA. We present a Dutch case series and review of the literature.

The Kearns-Sayre syndrome is a rare condition, characterized by progressive external ophthalmoplegia, retinal pigmentary degeneration and progressive impairment of cardiac conduction, which mainly determines the prognosis. Two young patients (aged 13 and 18 years) without symptoms of cardiac disease presented with an electrocardiogram showing sinus rhythm, a normal atrio-ventricular conduction time, right bundle branch block and a left anterior fascicular block. Electrophysiologic investigation showed prolongation of His-ventricular interval at rest, which further increased during atrial pacing. Because of the potential progression of the conduction abnormalities and threatening sudden death, we decided to implant a pacemaker in both patients. Ten months later one patient had become pacemaker-dependent. Prophylactic pacemaker therapy is advisable in patients suffering from the Kearns-Sayre syndrome, who have bifascicular block on the precordial electrocardiogram.

We examined the validity of the social inhibition component of Type D, its distinctiveness from negative affectivity, and value regarding emotional distress as measured with the DS14 in 173 coronary artery disease patients. In dimensional analysis, social inhibition and negative affectivity emerged as distinct traits. Analysis of continuous negative affectivity and social inhibition measures showed main effects for several emotional and inhibition markers and an interaction effect for social anxiety. Categorical analysis indicated that Type D patients reported more depression, negative mood, social anxiety, and less positive mood. Social inhibition is not a redundant trait, but has additional conceptual value.
