BACKGROUND Deceleration capacity (DC) is a novel electrocardiography (ECG) parameter characterizing the overall capacity of slowing down the heart rate. The aim of this study was to evaluate clinical and ECG covariates of DC in patients with the first episode of ST-segment elevation myocardial infarction (STEMI) treated with primary angioplasty.

We are in the midst of a rapidly evolving era of technology-assisted medicine. The field of telemedicine provides the opportunity for highly individualized medical management in a way that has never been possible before. Evolving medical technologies using cardiac implantable devices (CIEDs) with capabilities for remote monitoring permit evaluation of(More)
The precise mechanisms that cause atrial fibrillation (AF) are not completely understood. Clinicians should ask themselves whether AF is truly 'lone' or is the effect of an underlying, 'masked' disorder. Atrial fibrillation shares strong epidemiological associations with other cardiovascular diseases such as heart failure, coronary artery disease, valvular(More)
INTRODUCTION There is no consensus on the length of ECG tracing that should be recorded to represent adequate rate control in patients with atrial fibrillation (AFib). The purpose of the study was to examine whether heart rate measurements based on short-term ECGs recorded at different periods of the day may correspond to the mean heart rate and rate(More)
INTRODUCTION Over the last 10 years, there has been an increasing number of patients with pacemaker (PM) and cardioverter-defibrillator (ICD). This study is a retrospective analysis of indications for endocardial pacemaker and ICD lead extractions between 2003 and 2009 based on the experience of three Polish Referral Lead Extraction Centers. MATERIAL AND(More)
BACKGROUND In light of the results from the AFFIRM trial, the "rate control" strategy has become an accepted treatment modality for patients with atrial fibrillation (AF). Establishing effective rate control requires long-term monitoring of the heart rate. The aim of the study was to compare the heart rate and rhythm monitoring capabilities of the pacemaker(More)
OBJECTIVES We sought to determine the usefulness of ambulatory 24-hour Holter monitoring in detecting asymptomatic pacemaker (PM) malfunction episodes in patients with dual-chamber pacemakers whose pacing and sensing parameters were proper, as seen in routine post-implantation follow-ups. This aspect has not been widely discussed so far. METHODS AND(More)
BACKGROUND Permanent cardiac pacing is the treatment of choice for severe and symptomatic bradycardia. Patients undergoing emergency pacemaker implantation are stabilised earlier by the insertion of a temporary emergency pacing lead, and they experience more comorbidities than with planned admissions. AIM To identify the parameters associated with(More)
In this study, we present the case of the extraction of a non-functioning, abandoned, chronically implanted nine year-old lead with proximal extended frayed ending, displaced spontaneously into the subclavian vein. The seemingly inaccessible lead was extracted from the body using the femoral approach. The lead was looped with a pig-tail catheter, standard(More)
