Premature heart beat

If frequent they may indicate something more serious according to Google.

It depends on what precisely is going on. Most everyone has occasional PACs, (premature atrial contractions), and I do mean...everyone. However, if they become noticeable enough to begin to impact your sense of ease and wellbeing, it may signify that you are getting too many of them, and/or it may signify the onset of another arrhythmia which will need formal diagnosis and attention. So, in any case, your primary care provider should be apprised of this change...consult your doctor.
PACs are innocuous, generally, and most cardiologists and electrophysiologists will ask you to ignore them so that you don't fret and let them interfere with your quality of life. They are not dangerous. However, and I repeat, they can become burdensome, and in fact the medical term for their impact on one's health is known as 'the burden'. If your PAC burden is too high, usually between 3-8% of all beats (depends on your overall health and on the findings and experience of the cardiologist), then you may be treated one way or another, but that is to be determined later in consultation.

I live with them and have for several years. I am have over 10,000 a day but mostly I have anywhere from about 400-1000.

Most ectopic beats are harmless unless you have other more serious issues with your heart. As the person said above - most people get them at some point in their life. They’re not dangerous in the majority of people.

My experience with this is there are two different types of premature heart beats. PVCs which are ventricle and PACs which are atrial. You need to know which one you have to be able to address them.

They are not uncommon and almost everyone will have them from time to time. If they continue, area consistent, cause any side affects, you need to see a cardioloigist and even better a electrophysiologist.

I had tons of PVCs and mostly caused mental stress not physical issues. I take medication for it and reduced them by 50%. The medication also really reduced to a rare time frame temporary tacacardia.

I have a ICD/Pacemaker that paces my heart which gives me a good electrical beating where my heart was not doing because of LBBB and PVCs. The ICD will shock me out of tacacaria if continues. My new medication really had done a lot to not have tacacardia.

So are your premature heart beats PVCs or PACs. Most of the time a doctor will order a holter monitor to record you electrical history to determine how much you are getting PVCs and PACs and where they are coming from.

Frequent means a high burden of over 15,000 a day. It doesn’t sound like this person has that many.

Each of these is worth a few minutes of perusal. In the second citation, about 2/5 of the way down (determined by the position of the cursor on the right side margin) you'll find a useful chart showing curved lines dipping rightward with various colours. It's easy to understand and shows how increased burden of PACs over lengthening timeframes is associated with increased morbidity.
The last citation is a relatively easy and quick read and should make clear that you don't want more than about 77 PACs each day if you can help it.

I have had PVC's for a long time - maybe all my life. I have never had a "normal" EKG. I have worn a Halter monitor several times that identified the frequency of my PVC's - about 33% of my heartbeats. I never had any symptoms so my doctors never did anything except monitor them. I got a pacemaker after several severe episodes of bradycardia and then developed Afib and was put on a blood thinner and antiarrhythmic. Recently had ablation and am going for my follow-up in two weeks. I assume the PVC's are still there, but as I said I have never had symptoms related to them. Will see where I stand in two weeks.
