It is common to use very high electric fields (E) to defibrillate hearts, which can damage cardiomyocytes, showing the importance of developing methods that can decrease the E applied in defibrillation protocols. We used COMSOL Multiphysics software

Background In cell biology, increasing focus has been directed to fast events at subcellular space with the advent of fluorescent probes. As an example, voltage sensitive dyes (VSD) have been used to measure membrane potentials. Yet, even the most re

The insect heart (dorsal vessel, DV) is considered a valuable model for studies on cardiac genetics, development, and physiology. However, as software for monitoring and quantitation of insect cardiac activity is not commercially available, most stud

Insect and vertebrate hearts share the ability to generate spontaneously their rhythmic electrical activity, which triggers the fluid-propelling mechanical activity. Although insects have been used as models in studies on the impact of genetic altera

Background Considering the clinical importance of the ventricular fibrillation and that the most used therapy to reverse it has a critical side effect on the cardiac tissue, it is desirable to optimize defibrillation parameters to increase its effici

Action potentials are non-linear variations of the transmembrane potential caused by changes in the membrane conductance. In 1952, Hodgkin and Huxley proposed a set of differential equations that describes mathematically the conductance changes obser

Isolated cells are often chosen for study rather than whole tissues because they can sufficiently represent systems of great complexity. However, conducting experiments with isolated cells is greatly hampered since the available environment is, at fi

Introduction Cardiovascular diseases represent a major cause of death world-wide and one of their greatest complications is the development of cardiac arrhythmias, in which ventricular fibrillation (VF) stands out as the most severe one. The only the
