[Clinical and experimental results with acupuncture-analgesia (author's transl)].

Operations under acupuncture analgesia have been performed in Vienna since March 1972. A total of 102 procedures has been performed with "classical" Chinese acupuncture analgesia. Additionally given analgesics, psychodynamic factors and neurophysiological components are of joint importance. Our success rate in these cases was 64 p.c. Since October 1972 we call "two-phase-acupuncture-analgesia". Up to June 1975 72 operations were performed under some modifications of this method. In a neurophysiological study 17 volunteers and in 2 patients undergoing stereothalamotomies depression or even disappearance of evoked potentials was be observed during acupuncture with alectrical stimulation. Thus an interaction between pain stimuli and acupuncture stimuli in the thalamus could for the first time be demonstrated in man.

[A prognostic index in acute myocardial infarction: discrimination analysis of clinical parameters on admission to hospital (author's transl)].

In 301 patients admitted to an intensive-care unit because of acute myocardial infarction a prognostic analysis was undertaken, based on 21 parameters (history, condition on admission, laboratory results) and related to ultimate outcome. Although some parameters were singly of prognostic value, discrimination analysis markedly improved predictive value. A prognostic index was constructed from seven easily available parameters: age, pulmonary congestion, leucocytosis, peripheral vasoconstriction, systolic blood pressure, site of infarct and hypertension. For those in a low-risk class (index less than 60, death-rate up to 5%), duration of stay in the intensive-care unit may be shortened and rehabilitation measures accelerated. Those at moderate risk (index 60-90, death-rate up to 25%) require careful monitoring. The highest risk classes (index 90-120, death-rate up to 90%; and index more than 120, death-rate more than 90%) require specially intensive and long-term monitoring, and various procedures for assisted circulation and possible cardiacsurgical intervention should be considered from the outset.

[Re-entry mechanism of ventricular tachycardias in the syndrome of nonhomogeneous delayed repolarisation (author's transl)].

The syndrome of Jervell and Lange-Nielsen with its characteristic combination of Q-T-(U) abnormalities and recurrent episodes of ventricular tachycardia (VT) or ventricular fibrillation can serve as a model for establishing recycling excitation (re-entry) as the likely cause of VT. The ECG abnormality in the Q-T-(U) segment indicates the underlying asynchronous repolarisation, probably localized in the His-Purkinje system. Asynchronous delayed repolarisation facilitates re-entry excitations. A personal case is reported which demonstrated two different patterns of inducing premature beats and VT, indicative of two different fascicular pathways of circus movement. The inducing extrasystole determines the circuit pathway and thus the ECG pattern of VT. The VT shows a fixed time relation depending on conduction delay and refractory period, which is a further indication for an underlying re-entry mechanism. Spontaneous changes in time relation or morphology point toward alterations in circuit pathways and can terminate the VT. Clinical findings in three further cases of the syndrome are reported. Furthermore, the possible general significance of these findings is highlighted by the occurrence of the described phenomena in seven patients in whom Q-T-(U) abnormalities exist merely as transient symptomatic disturbances.
