Generation of Monophasic Action Potentials and Intermediate Forms

Monophasic action potentials in man.

Transmural recording of monophasic action potentials.

To investigate the possibility of transmural recording of repolarization through the ventricular wall, KCl monophasic action potential (MAP) electrodes positioned along plunge needles were developed and tested. The MAP electrode consists of a silver wire surrounded by agarose gel containing KCl, which slowly eluted into the adjacent tissue to depolarize it. In six dogs, a plunge needle containi...

Monophasic and diphasic action potentials of the stomach.

T HERHYTHMICACTIVITY of thestomach is associated with action potentials which are similar to those of other visceral muscles, including the heart (I). In the work reported here, these potentials were further analyzed by recording monophasic potentials and by leading off separately from longitudinal and circular muscles. Also the action of some drugs was investigated. The fact that monophasic po...

Automated System for the Analysis of Heart Monophasic Action Potentials

In this paper we present an automated system, which can be used in real time for the analysis of heart monophasic action potentials (MAPs) in order to analyze the behaviour of the myocardium under pathological or normal conditions. The system can be described as a three-stage procedure. In the first stage MAPs are acquired using epicardiac electrodes or MAP Franz catheters and the noise is remo...
