INTRODUCTION Heart transplant recipients show an abnormal heart rate (HR) response to exercise due to complete cardiac denervation after surgery. They present elevated resting HR, minimal increase in HR during exercise, with maximal HR reached during the recovery period. The objective of this study was to study the frequency of normalization of the abnormal(More)
OBJECTIVE Exercise capacity has been shown to be reduced among cardiac transplant recipients. This observation is directly connected to both the transplanted heart's dependence on circulating catecholamines and the abnormal sympathoadrenal response to exercise in these patients. Taking into account this background, there is reluctance to use beta-blockers(More)
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(More)
INTRODUCTION AND OBJECTIVES The aim of this report was to describe the results of an analysis of the data on pacemaker implantations reported to the Spanish Pacemaker Registry during 2006. Special emphasis was placed on sociodemographic characteristics and on the pacing modes implemented for different electrocardiographic indications. METHODS The data(More)
INTRODUCTION AND OBJECTIVES Our aim is to describe the analysis of the pacemaker implants and replacements reported to the Spanish Pacemaker Registry in 2010, with special reference to the selection of pacing modes. METHODS Data collection was based on the information provided by the European Pacemaker Patient Identification Card, which was processed(More)
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. We present a prospective study including all consecutive transplant recipients (n = 55) in a two-year period whose survival was greater than two months.(More)
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(More)
Currently, three areas of active development in cardiac pacing are of particular interest to clinical cardiologists. Biventricular pacing is now considered a type-I indication for adjuvant treatment in advanced and refractory heart failure. Consequently, some changes in everyday clinical practice will be seen when patients with end-stage heart failure start(More)
