BACKGROUND Electrocardiogram (ECG) monitoring in daily life is essential for effective management of cardiovascular disease, a leading cause of death. Wearable ECG measurement systems in the form of clothing have been proposed to replace Holter monitors used for clinical ECG monitoring, however, they have limitations in daily use because they compress the upper body, and in doing so, cause discomfort during wearing. OBJECTIVE The purpose of this study was to develop a wireless wearable ECG monitoring system including a textile ECG electrode that can be applied to the lining of pants and can be used in the same way as existing clothing wearing styles without compression on the upper body. METHODS A textile electrode having stretchable characteristics was fabricated by knitting a conductive yarn with polyester-polyurethane fiber and then silver compound coated, and an ECG electrode was developed by placing it on an elastic band in a modified limb lead configuration. In addition, a system with analog-to-digital conversion and wireless communication, and a smart phone application were developed allowing users to be able to check and store their own ECG in real time. A signal processing algorithm was also developed to remove noise from the obtained signal and to calculate the heart rate. For evaluation of ECG and heart rate measurement performance of the developed module, a comparative evaluation with a commercial device was performed. ECG was measured for five minutes each, in standing, sitting, and lying positions, and the root-mean-square error (RMSE) of heart rates measured with both systems was compared. RESULTS The system was developed in the form of a belt buckle with a size of 53×45×12 mm (width × height × depth) and a weight of 23 g. In qualitative evaluation, it was confirmed that the representative waveform of the ECG was clearly observed. From the results of the heart rate estimation, the developed system could track changes in heart rate calculated by a commercial ECG measuring device, and the RMSE of heart rate was 2.5 bpm, 3.3 bpm, and 2.6 bpm in standing, sitting, and lying positions, respectively. CONCLUSIONS The developed system was able to effectively measure the ECG and calculate the heart rate through simply wearing as existing clothing without upper body pressure. It is expected that general usability can be secured through evaluation under more diverse conditions. CLINICALTRIAL 1040198-200609-HR-061-02

As with all techniques which are relatively new and therefore underutilized, diamond knife sectioning in the physical sciences continues to see both developments of the technique and novel applications.Technique Developments Development of specific orientation/embedding procedures for small pieces of awkward shape is exemplified by the work of Bradley et al on large, rather fragile particles of nuclear waste glass. At the same time, the frequent problem of pullout with large particles can be reduced by roughening of the particle surface, and a proven methodology using a commercial coupling agent developed for glasses has been utilized with good results on large zeolite catalysts. The same principle (using acid etches) should work for ceramic fibres or metal wires which may only partially pull out but result in unacceptably thick sections. Researchers from the life sciences continue to develop aspects of embedding media which may be applicable to certain cases in the physical sciences.

Exercise training (ET) is now recommended as an important component of a comprehensive approach to patients with heart failure (HF). Despite the existence of proven benefits of ET, many HF patients remain physically inactive. Introducing telerehabilitation (TR) may eliminate most of the factors that result in the currently low number of patients undergoing outpatient-based rehabilitation programmes and thus increase the percentage of those who will undergo cardiac rehabilitation. Despite the fact that TR is highly applicable and effective, there are few papers dedicated to the study of TR in HF patients. Until recently, only a couple of home rehabilitation-monitoring models have been presented, from the simplest, i.e. heart rate monitoring and transtelephonic electrocardiographic monitoring, through to the more advanced tele-electocardiogram (tele-ECG) monitoring (via a remote device) and realtime electrocardiographic and voice transtelephonic monitoring. It seems the last two are the most useful and reliable. Based on published studies, TR in HF patients could be equally effective as and provide similar improvements in health-related quality of life to standard outpatient cardiac rehabilitation. In addition, adherence to cardiac rehabilitation seems to be better during TR. Due to disease-related limitations, TR seems to be a viable alternative for comprehensive cardiac rehabilitation in HF patients. Further studies are needed to confirm the utility of this type of rehabilitation in routine clinical practice, including its cost-effectiveness. Because of the diversity of technological systems, it is necessary to create a platform to ensure compatibility between the devices used in telemedicine.

Az akut coronariaintervenció korában a myocardialis infarctust elszenvedő beteg nagyon gyorsan, néhány nap után haza vagy rehabilitációra kerül. A betegeknek a halálozása ugyanakkor az infarktust követő első hónapban a legmagasabb. Az elsősorban veszélyeztetettek a jelentős szívizomvesztést elszenvedő, csökkent szisztolés bal kamrai funkciójú betegek. Fontos lehet ezért ezen betegeknél – a telemedicina fejlődésével lehetőséget teremtő – új módszerek kidolgozása a ritmuszavarok otthoni monitorozására. Célkitűzés: Annak vizsgálata, hogy internetalapú folyamatos otthoni aritmiamonitorozás milyen biztonságossággal alkalmazható akut myocardialis infarctust elszenvedő, coronariaintervención átesett, csökkent balkamra-funkciójú betegeknél a hazabocsátás utáni első hónapban. Módszer: Számos transztelefonos EKG-monitor-rendszer működik, de a szerzők egy olyan új technológiával szerzett tapasztalataikat ismertetik, ahol a beteg aktivációjától független, folyamatos EKG-észlelés zajlik interneten keresztül. Az internettel nem rendelkező betegeknél kifejlesztésre került egy mobil internetre csatlakozó vevőegység is. Eredmények: Tíz, infarktus után otthonába távozó, 40% alatti ejekciós frakcióval rendelkező betegnél végeztünk monitorozást. A mérések kumulatív ideje összesen 170 nap volt. A teljesen zajmentes időszak 98% volt, hibamentes EKG 99% volt. Hatvanhat összes alarm átlagos nyugtázási ideje 27 szekundum volt. Az alarm/nap 0,39-nak adódott, és a riasztások pozitív prediktivitása 0,106 volt. Az összes alarmidő 29,8 percnek adódott, ami napi bontásban 10,5 szekundumot jelentett. Következtetések: Módszerünk alkalmasnak látszik a kórházból hazakerült betegek otthoni monitorozására úgy, hogy viszonylag nagy százalékban lehet hibamentes EKG-t regisztrálni a kifejlesztett mellpánt segítségével. Az alacsony riasztási idő azt jelenti, hogy sok beteg egyszerre történő monitorozása is kellő biztonsággal megoldható. A fenti módszert és eredményeinket azért tartjuk fontosnak bemutatni, mert ilyen „szoros” otthoni monitorozásról sem publikációt, sem terméket, illetve szolgáltatást nem találtunk.
