  • Title: [Basic diagnostic program in dizziness and syncope symptoms: value of electrophysiologic studies of the heart].
    Author: Kettner W, Schröter U, Reinhold S, Wilckens H.
    Journal: Z Gesamte Inn Med; 1990 Sep 01; 45(17):503-6. PubMed ID: 2291272.
    Abstract:
    Syncopes and preceding signs and symptoms, particularly also in form of appearances of giddiness, are, including specialists of various branches, among others ENT, neurology, orthopaedics and ophthalmology, always to be classified according to the fact whether or not a cardiovascular disease is to be regarded as cause. If there is the suspicion, both special non-invasive investigations and such ones which possibly are to be performed invasively are indicated. The latter come after the non-invasive investigations partly on account of the expenditure (technique of heart catheterization) and the possibilities of complication. The testing of the sinus node with the highly frequent atrial stimulation and single stimulus technique, the lead of the His-potential and the performance of a ventricular programmed stimulation are the fundamental programmes of an electrophysiologic investigation. In an analysis carried out more than 3 years could be found that in two thirds of the 45 invasively examined patients the diagnosis could be precised and enhanced, respectively, and that the main disturbances related to the signs and symptoms were a sick sinus syndrome, AV-asequences and ventricular arrhythmias.
