[Intermittent Romano-Ward syndrome].
Two cases are described to have intermittent long QT syndrome. This type of long QT syndrome is not easy to recognize and the result could be fatal in case taking I/A type antiarrhythmic drugs. The first patient who was investigated had got "chinidin syncope" two years earlier, the second one had symptoms of syncope and dizziness for 3 months. The long QT syndrome was diagnosed in both cases by Holter monitoring. For these reason this paper underline the value of Holter monitoring as a diagnostic tool to establish the diagnosis of long QT syndrome. The monophasic action potential showed early after depolarisations in both cases.
