ABSTRACT
Endocardial monophasic active potentials (M.A.P.) recorded by suction --tip intracardiac catheters constitute a new research-- method in cardiac arrythmias, electrophysiology and pharmacology. The characteristics of MAP at auricular and ventricular levels are analyzed. The limitations of the method in its incapacity to record the MAP of conduction tissues is discussed. This method of recording MAP is evaluated with antiarrythmic drugs of tipes I, II, III and IV. The results are identical to recordings performed with intracellular microelectrodes.
