A high prevalence of prolonged QT interval duration has been observed among haemodialysis (HD) patients. The aim of this cases series was to describe the association of various risk factors with total mortality and sudden cardiac death (SCD) in this population. ⋯ In a case series of HD patients, QTc was associated with total mortality and SCD. Further studies to test this hypothesis in a larger population are necessary.

Cryoballoon ablation (CBA; Arctic Front, Medtronic) has proven very effective in achieving pulmonary vein isolation. Real-time three-dimensional transoesophageal echocardiography (RT 3D TEE) is a novel technology, which permits detailed visualization of cardiac structures in a 3D perspective. The aim of the present study was to assess the feasibility, advantages, and safety of RT 3D TEE in guiding CBA in a series of patients affected by paroxysmal atrial fibrillation. ⋯ Cryoballoon ablation is safe and feasible under RT 3D TEE guidance. This imaging tool permits perfect visualization of all PV ostia and neighbouring LA structures. Most importantly, it proved very efficient in guiding the operator to achieve complete occlusion and successful isolation in all veins.

Remote monitoring of pacemakers and implantable cardioverter defibrillators (ICDs) has emerged as a tool to replace regular follow-up of such devices, and to detect hardware failure, arrhythmias, and heart failure decompensation. The Asia-Pacific region is a geographically diverse area, with widely different cardiac device implant rates and expertise. However, common to all countries, distance and logistic for patients to reach an expert monitoring centre for routine follow up are significant, and in some countries, this will likely be replaced by remote monitoring. ⋯ Cost, lack of reimbursement, and logistic support are major issues in widespread application of remote monitoring technology. In conclusion, remote monitoring is increasing in Asia-Pacific region despite the increase in cost. Implantable cardioverter defibrillators and CRT/CRTDs are more likely than pacemakers to be enabled with remote monitoring.

Atrial fibrillation (AF) is the most common cardiac arrhythmia. 'Silent', undiagnosed AF is often only detected with the first complication, e.g. a stroke. Detection of 'silent' AF prior to the first cerebrovascular event would be valuable to institute adequate therapy and prevent complications related to AF. We performed a simple electrocardiography (ECG) screening for silent AF in patients at risk for AF. ⋯ A simple ECG screening could help to detect 'silent' AF prior to the first cerebrovascular events, especially in patients with multiple cardiovascular conditions. Larger studies of such a screening are warranted.
