Facilitation of DDD follow-up using the DDT mode.

To facilitate follow-up, modern dual chamber pacemakers provide a variety of diagnostic features like ECG interpretation channels and intracardiac electrograms. For evaluation of the sensing performance at rest and during exercise, for assessment of the presence of crosstalk, and for measurement of the retrograde conduction time, dual chamber triggered pacing, particularly the DDT mode, can be used alternatively or additionally in pacemakers equipped with this option. In contrast to ECG interpretation channels, ECG documentation is not required for evaluation of the sensing performance, because the triggered pulses serving as markers for sense events can also be seen on the monitor. Selection of the DDT mode not only as temporary but also as permanent program serves to facilitate pacemaker ECG interpretation for exercise tests and Holter recordings as well.

[Assessment of prognosis in acute myocardial infarct after reaching the maximum enzyme activity].

A new method is described for estimation of the prognosis of acute myocardial infarction progress due to temporary decrease in the isoenzymes, i.e. malic dehydrogenase (MDH), aspartate aminotransferase (ASAT), lactic dehydrogenase (LDH), and the decrease in the creatine kinase (CK). It is shown that the time of enzymatic activity is an essential factor. If 120 hours of decrease in enzymatic activity of MDH, LDH, and CK are exceeded, the prognosis of the myocardial infarction deteriorates dramatically.

[Prognosis assessment of acute myocardial infarction on the basis of temporal changes of isoenzyme activities].

A new method is described for determining the prognosis of acute myocardial infarction (AMI) progress due to temporal increase in the isoenzyme, i.e. malic dehydrogenase (MDH), aspartate aminotransferase (ASAT), lactic dehydrogenase (LDH), and the increase in the creatine kinase (CK). It is shown that the time of enzymatic activity is an essential factor. If 25 hours of increase in enzymatic activity of MDH and CK are exceeded, AMI deteriorates dramatically.

[Aspects of myocardial infarction treatment in patients of higher age (author's transl)].

The influence of a 6 weekly physical training of the performance in patients of the age between 60 and 70 years who have had a definitive myocardial infarction has been tested in phase II or rehability. Dayly in patient and under physicinal control the conditioning were executed in the time of 30 minutes on a bicycle--hometrainer. The personal intensity of training was choosed so that anwunted to 60--70% of heart-frequency obtained by the maximal exercise. Additional a terrain-training was taken part. Under conditioning a different relation of performance was recognized by patients (12 patients--performance decreased, 15 patients--constant performance, 33 patients--performance increased). To prevent a negative development of physical performance the result of performance--pulse (N/Hf) should be observe especially.

[Clinical-pharmacological effective data on 3',4',-dipropionylhelveticosol].

In experiments of treatment carried out on 39 patients with cardiac insufficiency with tachyarrhythmia for the partially synthetic, new heart glycoside 3',4'-dipropionyl helveticosol the following clinico-pharmacological data of efficacy were approximately established on an average: level of full efficacy 2.7 mg, daily coefficient of disappearing 40%, coefficient of enteral absorption 30%, daily maintenance dose intravenously 1.1 mg and orally 3.7 mg.
