I’m a 30-year-old marketing manager, and three years ago, a flu I should have recovered from left me with symptoms that never fully resolved.<\/span><\/p>

For the first six months, I thought it was post-viral tiredness and that I should give it time.\u00a0<\/span><\/p>

Then I started fainting when I stood up. My heart would race walking from my desk to the kitchen for a glass of water. Hot showers became a problem. Standing in queues became a problem. Eventually, prolonged standing itself became difficult.<\/span><\/p>

What many people do not fully understand about Postural Heart Rate Abnormalities is how disruptive even low levels of exertion can become.\u00a0<\/b><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

I have a desk job. I sit at a laptop for a living, I’m not a nurse or a builder, and even that became something I had to ration.\u00a0<\/span><\/i><\/p>

A morning of back-to-back meetings could leave me unable to function for the rest of the day.\u00a0<\/span><\/i><\/p>

Standing presentations often left me visibly unwell and physically shaky. Some weeks, the commute itself, on my feet on a train, was the hardest physical thing I did.<\/span><\/i><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Eventually, a cardiologist diagnosed me with Postural Heart Rate Abnormalities, which stands for Postural Orthostatic Rapid Heartbeat Syndrome.<\/span><\/p>

The short version is that my autonomic nervous system, the system that’s supposed to handle things like keeping blood pressure stable when I stand up, no longer regulates these processes efficiently.<\/i><\/b><\/p>

I’ve been working with my medical team for two and a half years now: beta blockers, increased sodium intake, compression garments, intermittent IV saline during severe symptom periods, and a cardiology team I see every six months.\u00a0<\/span><\/p>

None of that has changed, and I want to be clear before I go any further.\u00a0<\/b><\/p>

Nothing I say in this article is medical advice, and I haven’t stopped any of my therapy. I’ve just added something alongside them.<\/span><\/p>

What I’ve added is a vagus nerve stimulation device.<\/span><\/p>

I’d been considering it for a year, ever since my cardiologist mentioned in passing that some of his care recipients with autonomic dysfunction had told him they found it helpful.\u00a0<\/span><\/p>

He emphasised that the evidence remains preliminary.\u00a0<\/b><\/p>

He said the research is still preliminary and he couldn’t recommend it as a therapy, but he didn’t see any harm in trying it alongside my existing care.<\/span><\/p>

I had a rough few weeks of symptoms in the autumn. I thought about it for a while, ordered one, and decided to keep a journal for thirty days.\u00a0<\/span><\/p>

Here’s what actually happened.<\/b><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

It came in a plain white box.\u00a0<\/span><\/p>

I clipped it onto my left ear while sitting on the sofa, because I try to minimise unnecessary standing whenever possible. The sensation was a faint tingle, not unpleasant, just present.<\/span><\/p>

For three days, I noticed nothing.\u00a0<\/b><\/p>

My standing heart rate was still doing what it does, my energy was what it was, and the post-shower symptom flare was still a feature of my mornings.<\/span><\/p>

On day four, I wore it for a longer session, around an hour, while working from the sofa. Around the forty-minute mark, I noticed something I hadn’t expected. The persistent background physiological tension I always carried, the sense of anticipating symptom flare-ups, had eased.<\/span><\/p>

I’d been so used to that buzz that I’d stopped noticing it was there.\u00a0<\/span><\/p>

Noticing that the tension eased was the first sign that something might be happening.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Mornings are hard with Postural Heart Rate Abnormalities: I usually need an hour after getting up before I feel anywhere close to functional; heart racing, lightheaded, difficulty adjusting to standing.<\/span><\/p>

By the second week, I was doing a session first thing, still sitting up in bed before I tried to stand.<\/span><\/p>

On day eleven, I stood up, walked to the kitchen, made my coffee, and didn’t have to sit back down. I sat down anyway out of habit, but I didn’t have to.<\/span><\/p>

That was new.<\/b><\/p>

The same week, my afternoon crash, which usually arrived around 2 PM and significantly reduced my functioning for the remainder of the day, was softer. I still needed a rest, but I wasn’t fully incapacitated, and I actually got through my afternoon calls instead of rescheduling them.<\/span><\/p>

Symptoms like mine have been linked to autonomic dysregulation, where the autonomic nervous system, which regulates involuntary bodily functions, has difficulty regulating these functions efficiently.<\/b>\u00a0<\/span><\/p>

Vagal tone is one part of how that system stays balanced, and lower vagal function has been associated with poorer autonomic regulation in some research.<\/span><\/p>

I’m not a healthcare professional, and I don’t claim to understand the mechanism fully.\u00a0<\/span><\/p>

However, I did notice meaningful changes subjectively, and this journal records it.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

My sleep had been significantly disrupted for years.\u00a0<\/span><\/p>

Postural Heart Rate Abnormalities often do this, partly because lying down and standing up both ask the autonomic system to adjust, and partly because anxious thoughts about the symptoms keep the persistent physiological hyperarousal.<\/span><\/p>

In week three, I started sleeping through the night again. Not every night, but more than I had in two years.<\/span><\/p>

The cumulative effect was the most noticeable thing.\u00a0<\/b><\/p>

When I’d had two good nights of sleep in a row, my overall functioning improved the following day: my standing tolerance was better, my afternoon energy was steadier, and the symptom flares became less severe, and they didn’t last as long.<\/span><\/p>

Other things I noticed:<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
