PURPOSE: Recent studies suggest that atrial fibrillation (AF) is associated with increased cardiovascular risk and mortality including sudden cardiac death (SCD). According to the Cardiovascular Heath Study cohort, the incident rate of SCD was higher in the AF population (2.9 per 1000 per year) compared with non-AF controls (1.3 per 1000 per year). In this study, we performed a systematic review and meta-analysis to explore the association between AF and SCD. METHODS: We comprehensively searched the databases of MEDLINE and EMBASE from inception to January 2017...

Complete atrioventricular (AV) block in association with Takotsubo syndrome (TS) has been well recognized, but the cause and effect relationship has not been elucidated. We describe a 78-year-old female who presented with complete AV block but one week later developed new-onset, diffuse T-wave inversions, QT prolongation, and acceleration of junctional escape rate. Left ventriculogram revealed features typical of TS. One year after permanent pacemaker implantation, complete AV block persisted despite the reversal of wall motion defects implying that conduction abnormality was the trigger of TS rather than its consequence...

The demand for tricuspid valve (TV) surgery has increased continuously these last years. Recent registry data have confirmed that TV repair or replacement carry an increased risk of conduction disorders requiring permanent pacemaker implantation, specifically for patients having multivalve surgery. The implantation of an endocardial right ventricular lead in those patients may impair TV function, and some other approaches may be discussed to avoid traversing the valve. This contemporary review describes the different options currently available for patients requiring pacemaker or defibrillation leads implantation after TV surgery...

With the alarming rise in the deaths due to cardiovascular diseases (CVD), present medical research scenario places notable importance on techniques and methods to detect CVDs. As adduced by world health organization, technological proceeds in the field of cardiac function assessment have become the nucleus and heart of all leading research studies in CVDs in which electrocardiogram (ECG) analysis is the most functional and convenient tool used to test the range of heart-related irregularities. Most of the approaches present in the literature of ECG signal analysis consider noise removal, rhythm-based analysis, and heartbeat detection to improve the performance of a cardiac pacemaker...

Pigment-Dispersing Factor (PDF) is an important neuropeptide in the brain circadian network of Drosophila and other insects, but its role in bees in which the circadian clock influences complex behaviour is not well understood. We combined high-resolution neuroanatomical characterizations, quantification of PDF levels over the day and brain injections of synthetic PDF peptide to study the role of PDF in the honey bee Apis mellifera We show that PDF co-localizes with the clock protein Period (PER) in a cluster of laterally located neurons and that the widespread arborizations of these PER/PDF neurons are in close vicinity to other PER-positive cells (neurons and glia)...

BACKGROUND: Transthoracic impedance measurements (TIM) is primarily used for minute ventilation (MV) rate adaptive sensors in pacemakers. With elevated impedance the TIM electrical signal itself is oversensed causing device malfunction. OBJECTIVE: We report an increased incidence of TIM oversensing. METHOD: Retrospective chart review. We review existing records of 18 patients who have demonstrated device malfunction with TIM oversensing. RESULTS: We have found a 1...

The heart rate is dynamically controlled by the sympathetic and parasympathetic nervous systems that regulate the sinoatrial node (SAN). HCN4 pacemaker channels are well-known causative molecule of congenital sick sinus syndrome. Although HCN4 channels are activated by cAMP, the sympathetic response of SAN was preserved in the patients carrying loss-of-function mutations of HCN4 gene. In order to clarify the contribution of HCN4 channels in the autonomic regulation of SAN, we developed novel gain-of-function mutant mice in which expression level of HCN4 channels could be reversibly changed from zero to ∼3 times of that in wild type mice, using tetracycline trans-activator and tetracycline responsive element...

BACKGROUND: A proportion of patients who undergo an initial lead extraction procedure will require a second, repeat extraction. Data regarding this clinical entity are scarce and neither the predisposing risk factors for, nor outcomes from these procedures have been described previously. We sought to determine the incidence, risk factors and outcomes of repeat lead extraction. METHODS: A database of extraction procedures from 2001-2015 was analyzed. Repeat extraction procedures were identified and the indication for extraction was dichotomized into infection and lead related problems...
