Holter results showed non-sustained VTACH,what does this mean im terri

Please see your cardiologist who ordered test to give you medical advice.

I can pass on to you my personal experience with this but does not reflect your personal diagnosis.

I have a ICD/Pacemaker that records, PACs, PVCs, VTACH, and other electrical issues of heart. I have had many holter monitors done. What I can tell you by what was explained to me about my past diagnosis of non-sustained VTACH is that your heart goes into VTACH but corrects itself and not sustained event.

In my case this would mean my ICD/Pacemaker would not charge to shock me as heart corrected itself.

It does show you need to address this with your cardiologist as to the cause and go over treatments if needed. Stress and anxiety will add to PVCs if you have them and your comment about being terrified is not good for you mentally or physically.

Just know there are a lot of medication and procedures out there to help with cardiology conditions. Without knowing how long or your medically history (which should be a medical professional) can't comment on how serious is for you.
Please though contact your cardiologist and advice them you are terrified about the diagnosis.

We understand why you are terrified. Horrible news, or mystifying at best, and it doesn't sound good at all!

It means that you have an electrically disordered heart that is allowing the AV node (Atrio-ventricular node, the lowest in the heart that passes on beat signals from the Sino-atrial node up in the right atrium) to send signals via other-than-normal paths, so you get extra beats. It can be serious, it can be relatively innocuous....depends on the patient. Yours comes and goes, so that's good. Yes, seriously, so far so good...IF you have to have VTach at all.

Here is a link to get you started on learning what you have, it's possible paths going forward, and what is likely to be done for you given which type you have and its prognosis. Please do ask your caregivers as many questions as you can think of so that you feel better about what is ahead for you.
