Background: The number of patients with cardiac implantable electronic devices in whom magnetic resonance imaging (MRI) is indicated is constantly increasing. The potential risk of electromagnetic interference has limited its use and it is still contraindicated by the Food and Drug Administration in some cases. The aim of this study is to evaluate the safety and efficacy of MRI in these patients.

This article discusses the main advances in cardiac arrhythmias and pacing published between 2013 and 2014. Special attention is given to the interventional treatment of atrial fibrillation and ventricular arrhythmias, and on advances in cardiac pacing and implantable cardioverter defibrillators, with particular reference to the elderly patient.

Its easy use and safety have extended its use to secondary hospitals (those without an Electrophysiology Lab). The aim of the study was to compare results between secondary and tertiary hospitals.

Background: The implantable loop recorder (ILR) is a useful tool for diagnosing paroxysmal conditions potentially related to arrhythmias. Most investigations have focused on selected clinical studies or high-volume centers. The aim of this study was to evaluate the indications and outcomes of the ILR in real clinical practice.

We describe a 72-year-old man referred for implantation of a cardiac resynchronization therapy device who had previously undergone repeated operations to replace the mitral valve. Retrograde venography of the coronary sinus (CS) to implant the left ventricular (LV) pacing lead revealed aneurysmal dilatation of the CS with LV-CS fistula that hindered-but did not prevent-complete implantation of the system.

This review summarizes recent scientific developments in ambulatory monitoring and its legal implications in appropriately selected patients. It also considers how new cardiac pacing devices can be used in the clinical monitoring of atrial fibrillation, sleep apnea and, in transplant patients, heart failure and transplant rejection. In addition, the system of accreditation for cardiac pacing services in Spain is outlined, with a focus on process development and quality indicators.

Background: The effect of left ventricular (LV) systolic function on the long-term left ventricular pacing and sensing threshold is unclear.
Methods And Results: We studied the effect of LV ejection fraction (LVEF) on the LV pacing and sensing threshold in 56 patients (mean age: 70.2 +/- 10.
