    Abstract Zebrafish heart has evolved as an intensely studied model for cardiac development, physiology and pathophysiology. A particular advantage is its morphological and functional similarity to mammalian, especially human heart. Zebrafish are simple to breed, uncomplicated to handle and easy to modify genetically. Because of the transparency of the early embryo, drug effects on heart rate and rhythm can be observed directly. Here we will compare the ionic basis of the electrophysiological properties of the zebrafish to those of other mammalian hearts and discuss the suitability of zebrafish as a model organism for human electrophysiology.

    Abstract Women have a longer QT interval than men, which appears to evolve after puberty suggesting that sex hormones have an influence on cardiac electrophysiology. Sex hormones do in fact regulate cardiac ion channels via genomic and nongenomic pathways. Women are at greater risk for life-threatening arrhythmias under conditions that prolong the QT interval. In addition, women exhibit greater sensitivity to QT interval-prolonging drugs. Female sex has also an impact on propensity to cardiovascular disease, including atrial fibrillation. However, ex vivo recorded atrial action potentials (APs) from female and male patients in atrial fibrillation did not exhibit significant differences in shape, except that APs from women had slower upstroke velocity. It is concluded that sex-related differences should be taken into account not only in the clinics, but also in basic research.

    Abstract In the wake of demographic change in Western countries, atrial fibrillation has reached an epidemiological scale, yet current strategies for drug treatment of the arrhythmia lack sufficient efficacy and safety. In search of novel medications, atrial-selective drugs that specifically target atrial over other cardiac functions have been developed. Here, I will address drugs acting on potassium (K
