    Notes: Abstract We report on two cases of mechanical termination of supraventricular tachycardia by chest thump which were followed by serious complications. In a 3-year-old boy with an otherwise normal heart, incessant supraventricular tachycardia was converted to sinus rhythm by a single precordial thump. This, however was followed by thrombo-embolic infarction of the left-sided middle cerebral artery. In another case of a 9-year-old girl, recurrent episodes of supraventricular tachycardia were associated with Ebstein anomaly of the tricuspid valve. Chest thump was successful in terminating supraventricular tachycardia but induced a short run of ventricular tachycardia which terminated itself and was then followed by sinus rhythm. It is concluded that even a slight precordial thump implies undetermined risks in the acute management of supraventricular tachycardia in children and should therefore be abandoned in favour of other methods.

    Description / Table of Contents: Zusammenfassung Ein neu entwickeltes System zur $$p_{a_{CO_2 } } $$ -geregelten Ventilation wird vorgestellt. Mit Hilfe einerp CO 2-Katheterelektrode (Fa. General Electric) wird kontinuierlich der arterielle Kohlensäurepartialdruck gemessen. Die in einenp CO2-Regler einlaufenden Potentiale werden mit einem variabel einstellbaren $$p_{a_{CO_2 } } $$ -Sollwert verglichen. Die Spannungs-differenz zwischen $$p_{a_{CO_2 } } $$ -Soll- und Istwert modifiziert die Ventilationsvorgabe eines mit Servo-Ventilen arbeitenden Beatmungsgerätes (Servo-Ventilator 900, Fa. Dräger) so lange nach, bis sich bei minimaler Regelabweichung $$p_{a_{CO_2 } } $$ -Soll- und Istwert entsprechen. Die Arbeitscharakteristika der einzelnen Glieder des Regelkreises werden besprochen.
    Notes: Abstract A newly developed system of $$p_{a_{CO_2 } } $$ -controlled automatic ventilation is demonstrated. ApCO 2-catheter electrode is used to monitor arterialpCO 2 continuously. The output voltage of thepCO 2 amplifier is fed into a regulator amplifier that compares it with a set voltage. The output voltage of the regulator controls an automatic respirator. All details of the automatic ventilation are described.
