Cellular basis for the monophasic action potential. Which electrode is the recording electrode?
BACKGROUND The cellular basis for the monophasic action potential (MAP) has long been a matter of debate. At the center of the controversy is the issue as to which of the two electrodes is the recording electrode and which is the indifferent electrode. The present study is designed to address this issue. METHODS Transmembrane action potentials (TAPs) and either intramural MAPs or contact (Fra...

متن کاملWhat is a monophasic action potential recorded by the Franz contact electrode?
by gest on M ay 3, 2016 D ow nladed fom After over 20 years of successful use of the Franz contact electrode technique by many others and myself (over 1000 publications to date), the recent paper by Kondo et al. [1] claims that it is not the tip electrode, but rather the distant-from-tip or bindifferentQ electrode that records the monophasic action potential (MAP). The introduction starts out b...
متن کاملTransmural 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...
متن کاملClass 3 antiarrhythmic action in man. Observations from monophasic action potential recordings and amiodarone treatment.
Nine patients with different supraventricular tachyarrhythmias were treated orally with amiodarone (a Class 3 antiarrhythmic drug) according to a standardized protocol. Eight patients had subjective or objective beneficial antiarrhythmic effects from the drug. The treatment was discontinued in 2 patients due to corneal opacifications. In all patients right atrial monophasic action potentials we...
