Summary

Monophasic action potential (MAP) recording plays an important role in a more direct view of human myocardial electrophysiology under both physiological and pathological conditions. The MAP method represents a very useful tool for an electrophysiological research in cardiology. Its crucial importance lies in the fact that it enables the study of the action potential (AP) of myocardial cell in vivo and, therefore, the study of the dynamic relation of this potential with all the organism variables what can be particularly helpful in the case of arrhythmias.

Hundred and fifty patients will be included to explore mapping capabilities in cardiac chambers in patients suffering from regular or fibrillating tachycardia's with the following inclusion plan: i) Atrial fibrillation at a total of 50 patients ii) Ventricular fibrillation or patients at high risk of sudden cardiac death at a total of 50 patients iii) Junctional tachycardia at a total of 50 patients. We will focus on cardiac activation (depolarization and repolarization) in this population.
