I had my appointment at the cardiologist today. My PVCs (premature ventricular contractions) have been really frequent and two weeks ago I had a panic attack at the shopping centre. My dad was with me and had no idea what the hell to do, so he called an ambulance. Monitoring again at the hospital showed a high frequency of PVCs but nothing else unusual. I was advised to go through with the cardiologist appointment and get an echocardiogram just to rule out anything dangerous. PVCs are usually no problem unless the person has a structural heart abnormality. I have been beyond stressed. Not exercising (too scared), and not putting everything into my study for my seminar this Friday (too distracted). I have to get my anxiety under control and I have started seeing a CBT therapist who coincidentally was a lecturer in exercise physiology which brings me to the diagnosis from the cardiologist.
About a year ago I started running again. Six months later I started to feel generalised anxiety sneaking back into my life. I thought I was done with that. How could I be the fittest, healthiest and most fulfilled in my life, but having MORE anxiety. It didn’t make sense. This coincided with a fluttery feeling in my throat which it turns out is my heart – my biggest fear. Well, it was.
The echocardiogram showed that I have a normal heart. The ECGs have shown my heart rhythm is normal. I don’t have cardiomyopathy. What I do have is a system that is sensitive to adrenaline and cortisol. When these hormones are elevated in my system, it causes another fibre to send a signal to my ventricles to beat. Usually, the signal comes through the sinus node at the top right of the heart, but PVCs are caused by the trigger coming from a different place. The ‘skipped beat’ that people say they feel is actually just the upper chambers pausing to catch up to the lower chambers which have beat early due to a false signal. It sounds so scary. But it is totally ok. Unless you have cardiomyopathy or structural heart damage, which I don’t. And PVCs don’t cause these either.
The cardiologist emphasised that EVERYONE, that is, EVERYONE, will have some of these in a 24 hour period. Unfortunately some unlucky people simply feel them and/or and have more than other people. And guess who those people are? According to Dr. Sharpe, they are people who are smaller, people who drink a lot of caffeine or take other stimulants, people who are overworked, overtired, and those of a certain, ahem, Type A personality. He stressed this last part. I asked why I get these if I don’t feel under pressure or stressed. There is no one reason. Physiology. Some people’s bodies can enter a state of high adrenaline and cortisol without the person realising it. Especially if you are a person usually prone to high anxiety. And yes, exercise increases adrenaline and cortisol and PVCs are very common in very fit people. So bugger off people who think exercise should always be an endorphin-inducing positive lifestyle habit 😀
So, the good news is I have BENIGN PVCs. The bad news is I will always have them, and they will be especially noticeable if I keep running. But I should not stop running as they are not dangerous. If I want to stop feeling them, I could try a certain beta-blocker as this stops the adrenaline receptors from firing and will reduce or eliminate the PVCs; but the only reason to take them is for comfort and not any medical reason. So I will see how I go without them.
I’m planning to try a slow 5k tomorrow morning. I haven’t been getting up as early as usual as I’ve lost a lot of motivation (and weight and fitness). My CBT guy told me if I get the all clear from the cardiologist I need to start training for a marathon and make sure this doesn’t get me down. I’m not going to train for a marathon – couldn’t think of anything worse! – but I am going to keep running and get my fitness back. And it would be a good idea to cut back on a bit of chocolate, haha. I told him that would have to wait till after Easter
First, I’ve got to get through my confirmation seminar on Friday without looking like a total fool!
