An intracardiac electrogram model to bridge virtual hearts and implantable cardiac devices [PDF]

arXiv, 2017
Virtual heart models have been proposed to enhance the safety of implantable cardiac devices through closed loop validation. To communicate with a virtual heart, devices have been driven by cardiac signals at specific sites. As a result, only the action potentials of these sites are sensed.

Determinants of cardiac output in health and heart failure

Experimental Physiology, EarlyView.
Abstract Sustained physical exercise depends on delivery of oxygenated blood to exercising muscle. At least among healthy individuals, bulk transport of blood is tightly matched to metabolic demand, such that cardiac output increases by ∼6 L/min for every 1 L/min increase in oxygen uptake. Multiple factors contribute to the regulation of cardiac output,

Durability as an index of endurance exercise performance: Methodological considerations

Experimental Physiology, EarlyView.
Abstract Endurance athletes routinely complete physiological assessments to predict performance, inform training programmes and monitor subsequent training adaptations. This profiling is typically performed with the athlete in a ‘fresh’ (i.e., rested) condition, but physiological profiling variables deteriorate during prolonged exercise. Durability has

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Nursing procedure in the temporary transvenous pacemaker implantation

NURE Investigación, 2013
The temporary transvenous pacemaker (MPTT) implantation is a technique that consists in stimulating artificially the heart when the natural pacemaker is unable to maintain the rhythm and the appropiate frequency.

A Beating‐Heart Procedure with Soft Robotic Guidance

Advanced Robotics Research, Volume 1, Issue 1, April 2025.
Robot‐assisted pacemaker lead placement through the coronary sinus enabled cardiac pacing in multiple in vivo studies. When compared with conventional clinical tools, the robot reduced procedural time, duration of harmful radiation exposure, and the possibility of tissue damage.
