[ES] En el presente trabajo fin de grado se estudiarán dos fenómenos bioeléctricos muy conocidos pero cuyas causas son imposibles de determinar mediante estudios experimentales: la isquemia en su fase aguda y la hiperkalemia, ...
[EN] Background Multipoint pacing (MPP) in cardiac resynchronization therapy (CRT) activates the left ventricle from two locations, thereby shortening the QRS duration and enabling better resynchronization; however, compared ...

[EN] Hyperkalemia, acidosis and hypoxia are the three main
components of acute myocardial ischemia. In particular,
the increase of extracellular K+
concentration
(hyperkalemia), has been proved to be very proarrhythmic
because ...
