Heart Rate

This study is a two-arm randomized parallel group trial designed to compare the effects of alternate nostril breathing vs diaphragmatic breathing on oxygen saturation and Heart-rate variability in hemodynamically stable post-PCI patients. Participants will be randomly allocated in a 1:1 ratio to alternate nostril breathing or diaphragmatic breathing and will receive the allocated intervention for 2 consecutive days with three supervised sessions per day in addition to routine post-PCI care. Oxygen saturation will be assessed using a pulse oximeter and heart-rate variability will be assessed using a Polar H10 sensor at baseline and after the intervention. The study will determine whether there is a difference between two breathing interventions in the prescribed outcome measures.

Exam stress significantly affects the mental health and cognitive functions of nursing students. Audio-hypnosis offers a practical and low-cost intervention. Objective: To evaluate the effect of a single audio-hypnosis session on perceived stress, heart rate, and academic results. Methods: A pilot randomized trial will be conducted with 20 second-year students at ISPITS Safi, divided into an intervention group and a control group (n=10 each). Anxiety (VAS), heart rate (HR), and exam grades were analyzed.

Postural orthostatic tachycardia POTS is characterized by excessive increase in heart rate when moving from lying to standing position, often accompanied by symptoms such as dizziness, fatigue, brain fog, lightheadedness, rapid heartbeat and palpitation.it most commonly effects the females of reproductive age and can be triggered by events like viral infections, trauma and hormonal changes. During pregnancy females may experience worsening of symptoms in first trimester due to hormonal changes and decreased blood volume later on in second and third trimester the blood volume begins to increase. However, breathing exercises helps to regulate the nervous system, improves parasympathetic activity and reduce sympathetic activity. The study will be randomized clinical trial and will be conducted at Bashir hospital Sialkot and Fatima hospital Sialkot. The study will be completed in 10 months of duration after the approval of synopsis. Non probability convenience sampling will be used and 44 participants will be included in the study after randomization. The subjects will be divided into two groups. Group A (experimental group) will receive diaphragmatic breathing exercises whereas Group B (control group) will receive educational retraining whereas both groups will receive baseline treatments which includes progressive muscle relaxation techniques. The tools used for the study will be Vanderbilt orthostatic symptom score VOSS to evaluate orthostatic intolerance, blood pressure will be measured using non-invasive blood pressure measurement and pulse oximetry will be used to access the heart rate. After data completion data will be analyzed by using SPSS version 21.

This study aims to investigate the effects of music intervention on subjective anxiety and physiological indicators, including heart rate, blood pressure, and heart rate variability, in first-time ambulatory surgery patients, and to compare the differential effects between self-selected and standardized music interventions.

Ambient air temperatures in Mexico have broken record highs in 2024. Solutions are needed to build heat resilience in communities and adapt to increasing heat from climate change. Sunlight-reflecting cool roof coatings may passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions in the northern zone of Mexico are susceptible to increased heat exposure. Heat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are experienced in communities that are least able to adapt to heat exposure. By reducing indoor temperatures, cool roof use may promote heart health, sleep and physical activity in household occupants. The long-term research goal of the investigators is to identify viable passive housing adaptation technologies with proven health benefits to reduce the burden of heat stress in communities affected by heat in Mexico. To meet this goal, the investigators will conduct a randomized controlled trial to establish the effects of cool roof use on heart rate, sleep and physical activity in Colima, Mexico.

This randomized controlled trial (RCT) evaluates the effectiveness of music as a complementary intervention for pain control during non-surgical reduction of distal radius fractures in orthopedic patients. Distal radius fractures are among the most common traumatic injuries presenting to emergency departments and are frequently associated with intense procedural pain and significant physiological stress responses. Despite standard pharmacological analgesia, optimal pain management during fracture reduction remains a clinical challenge, and evidence regarding non-pharmacological adjuncts in the emergency orthopedic setting is still limited The study will enroll 192 adult patients admitted to the orthopedic emergency departments of AUSL Piacenza and AOU Parma with distal radius fractures requiring closed reduction. Participants will be randomly assigned (1:1:1) to one of three groups: a 20-minute session of patient-preferred music, a 20-minute session of standardized music selected by a music therapist, or standard care without music. Pain intensity will be assessed using the Numerical Rating Scale (NRS), while physiological stress will be evaluated through heart rate and blood pressure measurements, collected at baseline (T0) and 20 minutes later (T1), immediately after the reduction procedure The trial is designed as a prospective, randomized, controlled study with blinded data analysis, and all data will be collected and managed in compliance with current privacy and data protection regulations. By generating robust evidence on a low-cost, safe, and easily implementable intervention, the PolSound trial aims to improve procedural pain management and patient experience in emergency orthopedic care, potentially supporting the integration of music-based interventions into standard analgesic protocols.

The proposed project will evaluate the synergistic effects of a nutritional formulation, 'Think Tank' on cognitive performance following exposure to a psychological and physical stressor. Adopting a double-blind repeated measures cross-over design, middle-aged females (40-60 years) will be recruited to take part in a two-stage research study that will examine whether the formulation enhances cognitive performance and subjective well-being following the challenge of a stressor, compared to placebo. Cognitive assessments will examine the impact of the nutritional formulation on working memory, sustained attention, cognitive flexibility and inhibitory control. The study will also assess physiological (heart rate, blood pressure and cortisol) and subjective (well-being, anxiety, positive and negative mood, stress) markers of stress reactivity. The study will also explore levels sleep quality, mental and physical fatigue, effort, productivity, and perceived impact of the intervention.

This randomized, sham-controlled, crossover study investigates the acute autonomic effects of transcutaneous cervical vagus nerve stimulation (tcVNS) applied at five different frequencies (0 Hz/sham, 10 Hz, 25 Hz, 50 Hz, 100 Hz) in healthy adults. The primary objective is to determine how stimulation frequency modulates heart rate variability (HRV), blood pressure, and respiratory rate. The study aims to establish a frequency-specific dose-response model using validated physiological measurements.

The study will be conducted with the Crossover Randomized Controlled Method. The infants who have attained oral feeding in the neonatal intensive care unit will be divided into two groups via randomization in the computer environment. After the randomization, kangaroo care will be applied to the infants in Group 1 during the first feeding hour when they are included in the study and they will be breastfed by their mothers without any other application during the next feeding. On the other hand, no application will be performed on the infants in Group 2 during the first feeding hour when they are included in the study and kangaroo care will be applied to them during the second feeding hour. The infants in both groups will be breastfed by their mothers during the feeding hours.

: Patient readmission to PICU is a major point of concern for physicians because, although being a rare event, it has been strongly associated with more morbidity and death. Patient monitoring once they have left the PICU is drastically modified, and small connected devices could be an option to early identify patients at risk of PICU readmission. Such devices have been manufactured for the recording of vital signs in adults, but they do not exist for children. Besides, studies have recently shown that devices that use optical sensors may be less accurate in individuals with dark skin pigmentation since dark skin tones impose a limitation on optical biometric sensing. The wearable and medical device industry has not sufficiently addressed this issue yet. This is one of the main challenges that need to be addressed in this area to make sure the connected devices using this technology will work with all different skin colours including very dark skin.

Ambient air temperatures in Africa, have broken record highs in 2024. Solutions are needed to build heat resilience in communities and adapt to increasing heat from climate change. Sunlight-reflecting cool roof coatings may passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions- for example in informal settlements, slums, and low-socioeconomic households - are susceptible to increased heat exposure. Heat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are experienced in communities that are least able to adapt to heat exposure. By reducing indoor temperatures, cool roof application may improve heart health, sleep and physical activity in household occupants. The long-term research goal is to identify viable passive housing adaptation technologies with proven health benefits to reduce the burden of heat stress in communities affected by heat. To meet this goal, the investigators will use smartwatches to measure the effects cool roof application on heart health, sleep and physical activity in Ouagadougou, Burkina Faso.

The goal of this clinical trial is to learn if the reduction of the noises (through head phones with music and noise cancelling) that occur during wisdom teeth removal, leads to a significant reduction in fear levels in patients compared to patients who do not have any noise reduction. The main questions it aims to answer are: Do music and noise cancelling help patients to have less fear during wisdom teeth removal surgery by reducing the sounds of the surgery? Is there a difference between just the noise cancelling function or is it better to combine noise cancelling and music together? Participants will: Just come to their regular appointment (wisdom teeth removal) to our clinic, no follow ups needed. All participants will answer one questionnaire before and one after the surgery. All of them will have their rate of heartbeat measured for three times (before, during and after surgery, measured by a puls oximeter on the finger). They will be allocated to one of the three study groups (no headphones, headphones with noise cancelling or headphones with noise cancelling and music).

This will be a crossover controlled trial designed to recruit 40 participants, who will be divided into two groups of 20 subjects each. The participants will be randomly assigned to either Group A or Group B. Group A will receive the sleep electric blanket intervention for a period of 7 days, while Group B will serve as the control group without any additional intervention. After the intervention period, there will be a washout period of 7 days to ensure that any effects of the intervention have subsided before the crossover. Following the washout period, the groups will switch roles: Group B will then receive the sleep electric blanket intervention, and Group A will become the control group. This second phase will also last for 7 days, preceded and followed by the same assessment procedures as the initial phase. This design will allow for a comparison of the intervention's effects against a control period within the same group of participants, enhancing the study's internal validity.

This study with N = 225 participants (1 cohort of a minimum of 85 and maximum of 140 participants, and an additional cohort with 85 participants) over 9 visits has been designed to assess the accuracy of Aktiia.product-us systolic and diastolic blood pressure measurements against double-auscultation reference measurements. In order to induce blood pressure changes and to simulate ambulatory scenarios, the study participants will be asked to perform a set of activities, involving body position changes and physical exercises. Additionally, this study will compare the heart rate measured by Aktiia.product-us against the reference readings provided by a finger pulse oximeter (as per ISO80601-2-61). The reliability of the auscultation readings will be controlled with simultaneous volume-clamp measurements.
