I can only assume from your story that the SVTs are longer than just a few seconds. You mention they will wake you up and you are panicked. How long are your SVTs? Very sort bursts are not uncommon but I am talking about a couple of seconds and not minutes. It you are having 200 bpm for minutes that is not normal. You mentioned that last fall working in your garden you felt like you were having a heart attack. I think you wore a monitor for 2 weeks and "they found that, at first they were noticing an irregular heart beat, randomly." What kind of irregular heart beat did they find last fall? Are you diagnosed with different arrhythmias?
Do you have access to the results of the holter monitors results?
More information is better: age, weight, bp status, prescription drugs. How often are your SVTs and how long do they last?
I would say that you need to go to a different facility and get a 2nd opinion. Did you see an EP or just a standard cardiologist. I think you need an EP/ electrophysiologist and not a standard cardiologist. EPs specialize in electrical problems and cardiologists tend to be plumbers but the plumbers do some of the same tests as EPs but not understand the results as well as EPs.

Here is my most recent Holter from just 3 weeks ago. I am post op from an Ablation Sept 25 and this Holter was done as a follow up from my ablation to see how well my heart was functioning.

I having regular occurrences of Afib. I also was having PACs/PVCs with a burden of 25% which mean 25% of my heart beats were PACs/PVCs. So during one week of a monitor last year I had 200,000 aberrant SVEs. This recent monitor reading I only had 2363(< 1%) aberrant SVE beats which is a dramatic drop. Note I had 9 occurrences of SVT with the highest 126 BPM and lasting only 10 beats.
Over all the results listed below are consider very good.

Date/Time Confirmed: 1/16/2025 2:06 PM (CT)
*The predominant rhythm was Sinus.
*The Maximum Heart Rate recorded was 126 bpm, 01/10 12:33:00, the Minimum Heart Rate recorded was 41 bpm, 01/10 09:13:21, and the Average Heart Rate was 57 bpm.
*There were 337 VE beats with a burden of < 1 %. There was 1 occurrence of Ventricular Tachycardia with the Fastest episode 105 bpm, 01/10 12:06:24, and the Longest episode 3 beats, 01/10 12:06:24.
*There were 2,363 SVE beats with a burden of < 1 %. There were 9 occurrences of Supraventricular Tachycardia with the Fastest episode 126 bpm, 01/06 13:10:41, and the Longest episode 10 beats, 01/10 12:50:28.

I want to say thank you for all that have replied here. All the information is extremely helpful. I will try and answer some of the questions asked. When wearing my second heart monitor, last fall, the SVT’s occurred on 4 separate occasions at night, for over 20 seconds, heartbeats up to 200. So imagine you are sleeping soundly and then, boom the heart starts beating super fast. A heart would possible do this if , 1. Out of fear, like a fight or flight response, 2. If you were exercising fast and hard, 3. Or something electrical is off in the rhythm of the heart. In my case, 3 is the applicable answer because, at midnight, to approximately 6am, this happened 4 times. I was sleeping, and when your heart jolts from resting heart rate to 200, it wakes you up, you are panicked as to what is happening, and cannot understand what is taking place. As I stated before, the first halter, they only found a random arrhythmia occurring at times of stress, or high stressful activity. This would be when I was working in my yard for hours, gardening, etc. After that occurrence, they stopped meds, that they believed could have contributed, ie hormones, levothyroxine, but never took away the AEDs, and the symptoms got worse. Those medications were never reintroduced, so I do not believe they are the culprit. I have no history, or family history of heart issues. I never had an arrhythmia, until just a year ago, so I am at a loss. The bigger issue for me is the doctor being complacent and stating its normal, and his staff refusing to give a second opinion, So, I contacted the Mayo Clinic, and they are going to have a doctor contact me regarding this. I will let you know the outcome, as I will be talking with them early this next week. I am needing answers, and all the input, experiences, and conversations help immensely. I am looking forward to answers now. Thank you everyone.

Your cardiologist might want to consider a second ablation.
