heart rate

Abstract: Background: Complex chronic conditions like Long COVID and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome involve energy limitations and changes in heart rate variability (HRV) and resting heart rate (HR). Mobile health technologies now offer real-time, valid measurements of HRV...

I have been using a combination of apps for Pacing that utilise heart rate (HR) and heart rate variability (HRV) using Apple iWatch and iPhone. I have been using the watchME app and found it very useful, especially to monitor for conditions likely to induce PEM. Based on resting HR on waking...

Introduction: In patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) a higher-than-normal resting heart rate has been reported in a number of studies. As heart rate is linked to stroke volume, the present study explored the relationship between the supine heart rate and...

Abstract Key points The impact of SARS-CoV-2 infection on autonomic and cardiovascular function in otherwise healthy individuals is unknown. We show for the first time that young adults recovering from SARS-CoV-2 have elevated resting sympathetic activity, but similar heart rate and blood...

Abstract New Findings What is the central question of this study? This study sought to investigate whether central and peripheral hemodynamics during handgrip exercise were different in young adults 3–4 weeks following infection with of SARS-CoV-2 compared with young healthy adults. What...

Introduction Long-term COVID symptoms marked by autonomic dysfunction1 and cardiac damage2 following COVID-19 infection have been noted for up to 6 months after symptom onset,3 but to date have not been quantified, to our knowledge. Previous studies have found that wearable data can improve...

From @PhysiosforME "Participants needed for our study We are delighted to announce that recruitment has now begun for our feasibility study: “Feasibility of investigating oxygen consumption (VO2), heart rate, blood pressure, lactic acid levels and activity levels of people with Myalgic...

I happened to stumble across this POTS research today: Splanchnic Venous Compression Enhances the Effects of ß‐Blockade in the Treatment of Postural Tachycardia Syndrome Emily C. Smith, André Diedrich, Satish R. Raj, Alfredo Gamboa, Cyndya A. Shibao, Bonnie K. Black, Amanda Peltier, Sachin Y...

FYI useful summary from:

Heart rate and heart rate variability comparison between postural orthostatic tachycardia syndrome versus healthy participants; a systematic review and meta-analysis Joel Swai, Zixuan Hu, Xiexiong Zhao, Tibera Rugambwa & Gui Ming...

Wondering if PEM itself contributes to POTS. I remember reading Prof Neil McGregor's studies showing PEM involves a hypermetabolic state where we urinate out metabolites. Does anyone know if this contributes to orthostatic intolerance / lowered blood volume?

Hello - I have this morning received my Mio Alpha 2 Heart Monitor. I have managed to connect it to my phone, set up details and the heart rate zones etc but I have 2 questions I can’t seem to find via their support. I was wondering if anyone here could help. 1. If I want to see the heart...

Posted today (Jan 24 2018) by the ME Association. I thought this forum was a good one for discussion but if this thread should be posted elsewhere then please feel free to ask for it to be moved. I have not yet read this. And I can't join in any debate. No medical expertise plus "brain fog"...

https://autodidactauthor.wordpress.com/2017/12/18/which-heart-rate-monitor-for-me-cfs/ Bonus points obviously for saying nice things about S4ME @Clark Ellis ;)

People with ME/CFS usually find pacing the best strategy to try to avoid crashes and give the best chance of improvement over time. Some use activity diaries, others use step counters (pedometer/actometer), others use heart rate monitoring with the aim of using it to alert you to rises that...
