Surgical complications of cardiac implantable electronic devices: a systematic review and meta-analysis

Frontiers in Cardiovascular Medicine
AimTo identify the most common complications that occur after the implantation of a permanent pacemaker, and to estimate their prevalence. Method: systematic review and meta-analysis.

QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula

Pacing and Clinical Electrophysiology, EarlyView.
Abstract Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation

Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest

Experimental Physiology, EarlyView.
Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

Experimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

The Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

Novel volume‐electron microscopic ultrastructural analysis of gastrointestinal excitability associated with calcium–activated chloride channels

The Journal of Physiology, EarlyView.
Abstract figure legend Immunohistochemistry, electrophysiology and pharmacology are useful tools for understanding protein and channel expression and physiological reactions of calcium‐activated chloride channels (CaCCs). Conventional transmission electron microscopy has provided useful 2‐D information on organelle arrangement, localization and ...

Survey of ST-Segment Changes due to Active Lead Fixation during Permanent Pacemaker Device Implantation as a Prognostic Indicator of its Performance

مجله دانشکده پزشکی اصفهان, 2017
Background: Active lead implantation can create injury in myocardium that may be associated with a ST-segment elevation. This ST-segment elevation may be correlated with changes in other parameters such as threshold, sense, amplitude, impedance, and ...
