[Experiences with a cardiorecorder system for continuous 24-hour registration of heart rate].

TLDR
In this article, the authors discuss the kontinuierliche Registrierung der Herzfrequenz with einem transportablen Cardiocorder berichtet.
Abstract
Es wird uber die kontinuierliche Registrierung der Herzfrequenz mit einem transportablen Cardiocorder berichtet, der die minutliche Erfassung der Herzfrequenz fur Zeiten bis zu 24 Std erlaubt. Das GerAt besteht im Prinzip aus einem zweikanaligen TonbandgerAt, dessen Laufgeschwindigkeit so untersetzt ist, da\ eine normale Tonbandkassette C 60 fur eine Herzfrequenzregistrierung von 2×24 Std Dauer ausreicht. Auf der ersten Spur des Tonbandes werden die R-Zacken des EKG als Biosignale registriert; auf der zweiten Spur wird in minutlichen AbstAnden eine Zeitmarke aufgegeben. Mit Hilfe eines WiedergabegerAtes wird die 24stundige Aufnahme in ca. 15 min abgespielt. Durch einen eingebauten Impulsformer werden die Signale beider Spuren in digitale Rechteckimpulse umgewandelt. Diese in serieller Form vorliegenden Impulse werden durch ein Interface in einen ZAhler mit Hilfe der Zeitmarke in minutlichen AbstAnden gezAhlt; diese Werte stehen in BCD-Code parallel zur Weitergabe fur PeripheriegerAte wie: Schnelldrucker, Rechner, Kompensationsschreiber etc. zur Verfugung. Wird gleichzeitig die korperliche AktivitAt, standardisiert durch Selbstoder Fremdbeobachtung, ermittelt, so lassen sich diese Verhaltensmuster mit den Herzfrequenzwerten zur weiteren statistischen Verarbeitung zusammenbringen.

Atherosclerosis precursors in Finnish children and adolescents. X. Leisure-time physical activity.

TL;DR: The method developed for epidemiological estimation of habitual physical activity among 3 to 18‐year‐old Finnish boys and girls was discussed, discussing the reliability and validity of the method and the results of the application of this strategy are reported.

Work at sea: a study of sleep, and of circadian rhythms in physiological and psychological functions, in watchkeepers on merchant vessels. III. Rhythms in physiological functions

TL;DR: In this paper, it is suggested that these unwanted variations in operational effectiveness could be largely removed by replacing the 4-on/8-off watchkeeping system, with its associated "split" sleep pattern, by one which allows a single full length sleep each day.

The Applicability of The Edholm Scale for Activity Studies in Industry

TL;DR: The result showed that the changes in activities were overestimated in branch-specific and position-specific groups without particular physical work, and it was concluded that the classification of occupational activities should be carefully controlled with parallel recording of heart rate.

Chronopharmacology of cardiovascular medications

TL;DR: There is sound evidence that “time-of-day” has to be included in the authors' diagnostic and therapeutic strategies and different types of drugs may be superior to others when circadian time-related symptoms are concerned.

Work and cardiovascular health: viewpoint of occupational physiology.

TL;DR: The results indicated that the highest prevalence rates of obesity, hypertension and angina pectoris symptoms were found among men doing heavy physical work and having no sporting leisure activities, and in occupations with physical demands, both among women and especially among the men.

New method for heart studies.

Norman J. Holter
- 20 Oct 1961 - 
TL;DR: Electrocardiography is proposed to be implemented by the use of long-period, continuous recording of heart potentials with a portable, self-contained instrument together with semiautomatic methods for the rapid analysis of the resulting voluminous data.
