The RITHMI study: diagnostic ability of a heart rhythm monitor for automatic detection of atrial fibrillation.

Introduction And Objectives: Early detection of atrial fibrillation (AF) is a priority to reduce embolic events by initiating oral anticoagulation therapy. The aim of this study was to evaluate the diagnostic ability of a wrist device designed for automatic AF detection.

Methods: RITHMI is a prospective, comparative, observational study that included 167 patients referred to a cardiology outpatient clinic for a general consultation or for electrical cardioversion.

Spanish Pacemaker Registry. Ninth official report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2011).

Introduction And Objectives: To describe the results of the analysis of pacemaker implantations reported to the Spanish Pacemaker Registry in 2011, with particular reference to the population distribution and the selection of pacing modes.

Methods: Information provided by the European Pacemaker Patient Identification Card was processed using a purpose-built computer application.

Results: Data from 115 hospitals were analyzed, totaling 13,373 cards, representing an estimated 38% of implantations.

Cross-sectional study of cardiac resynchronization therapy in Spain. Indications, implant techniques, optimization and follow-up.

Introduction And Objectives: A cross-sectional study of cardiac resynchronization therapy use in Spain was performed to analyze problems with indications, implantation, and patient follow-up.

Methods: Spanish cardiac resynchronization therapy implanter centers were identified, then the department members were surveyed and the data were recorded by each implantation team.

Results: Eighty-eight implanter centers were identified; of these, 85 (96.

Ischemic time as a predictor of physical recovery in the first months after heart transplantation.

Functional results after heart transplantation range from modest to spectacular improvement. Little is known about factors to predict functional result. This study aimed to identify these factors.

Methods: Data collection was based on the information provided by the European Pacemaker Patient Identification Card, which was processed using a specially designed computer application.

Results: Information was received from 101 hospitals, covering a total of 11 648 cards.

[Progress in cardiac pacing].

This article contains a discussion of the most recent developments in cardiac resynchronization therapy, of the feasibility of performing magnetic resonance imaging in patients with cardiac pacemakers, and of the current and future status of leadless pacing. Finally, the most significant scientific articles published in the last year are reviewed.

Spanish Pacemaker Registry. Seventh official report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2009).

Introduction And Objectives: This article describes the finding of an analysis of all pacemaker implants reported to the Spanish Pacemaker Registry in 2009. Particular attention is paid to patients' demographic characteristics and to the pacing modes selected for various electrocardiographic indications.

Methods: The information provided by the European Pacemaker Identification Card was analyzed using a specially developed computer program.

[Progress in cardiac pacing].

This review discusses the utility and current status of remote monitoring in patients with cardiac devices in Spain, the different anticoagulation strategies used during device implantation, the surgical replacement and maintenance of pacemakers and defibrillators, and the present and future importance of impedance sensors in cardiac pacing and heart failure management. Finally, there is a summary of the most relevant scientific articles published in the last year.

Spanish pacemaker registry. 6th official report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2008).

Introduction And Objectives: This article describes the findings of an analysis of data on pacemaker implantations and replacements reported to the Spanish Pacemaker Registry during 2008.

Methods: The data came primarily from information recorded on European Pacemaker Patient Identification Cards.

Results: Data were received from 116 hospital units, which submitted a total of 11,855 identification cards representing 36.

Pacemaker malfunction or non-physiological ventricular pacing?

Pacemaker manufacturers have developed new algorithms to preserve intrinsic conduction in order to reduce unnecessary stimulation and looking for physiological pacing. This case report highlights some of the new challenges related to these algorithms which include possible ECG misinterpretations and inaccurate programming leading to potential negative consequences.
