[Bradyarrhythmias and pacemaker indications in elderly patients].

With the dramatic increase in the number of elderly people in most parts of the world and in our country there will be an accompanying increase in patients with sinus node dysfunction (SND) and atrioventricular (AV) block. For this reason, it will be essential for health care personnel to have a basic knowledge of bradyarrhythmias and the special considerations required for managing these rhythms in elderly patients. Because of frailty of this patient group indivualised approach and consideration for management of these patients must be done carefully.

Clinical situations in which coronary CT angiography confers superior diagnostic information compared with coronary angiography.

In this review, we aimed to outline the clinical and pathological conditions for which multidetector computed tomography coronary angiography (MDCT-CA) should be the preferred method because of its advantages over conventional coronary angiography (CCA). A consistent body of literature suggests that MDCT-CA is more than just complementary to CCA and that it provides more valuable diagnostic information in certain clinical situations, such as complex coronary artery variations, aorto-ostial lesions, follow-up of bypass grafts, myocardial bridging, coronary artery fistulas, aortic and coronary artery dissections, and cases in which the coronary ostia cannot be cannulated by a catheter because of massive atherosclerosis or extremely tortuous vascular structures.
