Cardiac Autonomic Control

A Variabilidade da Frequência Cardíaca (VFC) é um método não-invasivo utilizado para estimar o controle autonômico cardíaco que pode ser mensurada através do eletrocardiograma (ECG), método padrão-ouro. Dispositivos portáteis que tragam maior praticidade e com menor custo que o ECG, como os cardiofrequencímetros, são uma alternativa mais conveniente para a mensuração da VFC na prática clínica, porém é necessário que seus resultados sejam validados em diferentes populações. Objetivo: Analisar os estudos realizados sobre a validade dos cardiofrequencímetros em comparação com o ECG para mensuração da VFC no repouso em diferentes populações. Metodologia: Trata-se de uma revisão de literatura onde foram utilizados estudos publicados na base de dados do Pubmed e Scielo, sem limite inferior da data de publicação até o ano de 2021. Foram utilizados os seguintes descritores nos idiomas inglês e português: "heart rate variability" ou "cardiac autonomic control" ou "Electrocardiography" ou "Heart Rate", sendo associados aos termos “heart rate monitor” e "reproducibility" ou “validity” ou “agreement”. Resultados e discussão: Foram encontrados 15 estudos que avaliaram a validade de diferentes modelos de cardiofrequencímetros para a mensuração da VFC no repouso, em comparação com o ECG, em diferentes populações (adultos saudáveis, atletas, idosos, crianças, adolescentes obesos, indivíduos com lesão medular e idosos), assim como sua confiabilidade no teste-reteste de alguns dispositivos. Conclusão: Os estudos demonstraram que os diferentes modelos de cardiofrequencímetro podem ser utilizados como uma alternativa ao ECG para a mensuração da VFC, mesmo em diferentes populações.

The aim of this study was to assess the influence of various stimuli that confound interpretation of assessed indicators of horse welfare during rest and working period by the use of non-invasive methods of sampling. In total, 40 horses of different breeds and used for different purposes in Slovakia were used. The following indicators were tested: concentration of cortisol in saliva and 11,17-dioxoandrostanes in faeces measured by Elisa methods, heart rate and heart rate variability recording with the Polar Heart Rate Monitor and presence of stereotypical behaviour assessed with a horse questionnaire survey. The evaluated physiological responses were mostly affected by the type of work undertaken, especially horse movement intensity (P < 0.001) and horse equipment used during the working period (P < 0.01). Horses that showed stereotypical behaviour were less stressed during rest (P < 0.05) compared to horses without stereotypical behaviour. Horse breed, age, sex and stabling conditions affected only some of the heart rate indicators. The type of riding style had no fundamental influence on evaluated indicators. These observations highlight the difficulties in determining the welfare status in horses, since measurements can be affected by many factors that need to be investigated for achieving relevant outcomes. This is the first study in Slovakia focusing on the evaluation of horse welfare by non-invasive sampling.

Background: The modulation of heart rate by autonomic nervous system may be evaluated by the heart rate variability (HRV), which illustrates the fluctuations between RR intervals. To evaluate this analysis, the intervals between 2 QRS complexes are measured. In general, high HRV values are expected in healthy individuals; otherwise, low values are indicative of organism dysfunction. Studies conducted in healthy humans show that HRV suffers reduction with ageing and that there is autonomic immaturity in neonates. The aim of this study was to describe the characteristic pattern of cardiac autonomic behavior in healthy dogs in different age groups through short-term HRV analysis.Materials, Methods & Results: A total of 87 healthy dogs were studied. HRV was analyzed in time and frequency domain, using Holter and heart rate monitor. It was observed that puppies (below one year old) presented a lower parasympathetic predominance and, consequently, lower HRV values on time domain (SDNN, PNN50% e RMSSD) compared to the other 2 groups and on frequency domain (LF, HF and LF/HF) compared to the adult animals group (between 1 and 7-year-old), which presented higher HRV values when compared to the other groups. Elderly dogs (over 8-year-old) exhibited a natural tendency to decrease cardiac parasympathetic HRV indexes.Discussion: The use of the HRV method as a prognostic index and as an arrhythmogenic marker for various canine heart diseases presents interesting perspectives. However, before it may be employed for these purposes, a better understanding should be established regarding the physiological behavior of autonomic cardiac modulation in different age groups to serve as a basis for future analyses. This study observed that puppies presented higher values for HR and, therefore, shorter RR intervals than the other groups (adult and elderly dogs), what was observed on Holter and heart rate monitor methods (HRM). There were significant differences between puppies and the other 2 groups (adults and elderly) for all time-domain variables using both methods (Holter and HRM methods). SDNN was significantly lower in puppies compared to adults and elderly dogs. In addition, both RMSSD and PNN50%, which were more reliable over shorter periods of time, also presented means and medians that were significantly lower in puppies. Regarding frequency-domain HRV parameters observed on Holter method, these indexes were decreased on the elderly group compared to adult dogs, which is a possible effect of aging. Also, puppies revealed lower frequency-domain HRV parameters on both methods when compared to adult dogs. The influence of age on HRV is possibly related to the stage of development of an individual, starting at conception up to the maturity in relation to the mechanisms that cause variations in HR. There are studies in humans that suggest a gradual increase in parasympathetic activity during childhood, followed by a steady decrease as aging occur. The present study observed the same pattern in dogs. The balance between sympathetic and parasympathetic systems is influenced by age in dogs, which alters HRV values in the short-term. The HRV method´s analysis is relatively simple and non-invasive for assessing cardiac autonomic function; also, it is widely used in human medicine as a risk measure for sudden cardiac death. The 24-hour HRV analysis is highly challenging, as it is time-consuming, expensive, delays diagnosis, and has a large number of artifacts; in this way, standards for its short-term analysis were developed. Keywords: cardiology, autonomic nervous system, heart rate monitor, Holter.

Penelitian ini bertujuan untuk mengevaluasi alat ukur denyut jantung yaitu Polar Heart Rate Monitor dalam mengukur tingkat beban mental yang berbeda-beda dan mendeteksi terjadinya kelelahan mental. Penggunaan alat ukur ini jauh lebih praktis dan ekonomis jika dibandingkan dengan ECG (Electrocardiography), yang biasanya digunakan dalam penelitian laboratorium. Penelitian ini juga bertujuan untuk mengetahui parameter yang paling sensitif dalam mendeteksi tingkat beban mental yang berbeda-beda. Beberapa parameter yang dibandingkan adalah rataan denyut jantung, standar deviasi denyut jantung, koefisien α (konstanta DFA), koefisien D (konstanta Dispersional Analysis). Sebanyak 18 reponden yang terdiri dari 9 reponden laki-laki dan 9 responden perempuan dilibatkan dalam penelitian ini. Responden melakukan aktivitas mental dalam 3 tahapan proses aritmatika, yakni penjumlahan (beban mental rendah), pengurangan (beban mental sedang) dan perkalian (beban mental tinggi) masing-masing selama 20 menit. Hasil penelitian menunjukkan bahwa Polar Heart Rate Monitor sensitif untuk mendeteksi tingkat beban mental yang berbeda dengan mencari HRV (Heart Rate Variability) yakni dengan menggunakan nilai standar deviasi denyut jantung dan koefisien α. Kelelahan mental tidak dapat dideteksi baik dengan keempat parameter denyut jantung yaitu rataan denyut jantung, standar deviasi, koefisien α dan koefisien D.

Objective To analyze the relation between smoking and passive smoking with heart rate variability parameters in male adolescents. Methods The sample consisted of 1,152 males, aged 14 and 19 years. Data related to smoking and passive smoking were collected using a questionnaire. RR intervals were obtained by a heart rate monitor, on supine position, for 10 minutes. After collecting the RR intervals, time (standard deviation of all RR intervals, root mean square of the squared differences between adjacent normal RR intervals and the percentage of adjacent intervals over 50ms) and frequency domains (low and high frequency and sympathovagal balance) parameters of heart rate variability were obtained. Results No significant differences between smoker and nonsmoker adolescents were observed in heart rate variability parameters (p>0.05). Similarly, heart rate variability parameters did not show significant difference between exposed and not exposed to passive smoking (p>0.05). Conclusion Cigarette smoking and passive smoking are not related to heart rate variability in adolescence.
