They weren't able to sustain the svt long enough to ablate and discovered that my accesorry pathway is up against my SA node so I run the risk of needing a pacemaker if the svt is ablated. I was on metoprolol up until a week ago but was having frequent dose increases due to my svt breakthroughs on the med. I was up to 150 mg bid. I was also getting severe fatigue from the med. My cardio changed my med to verapamil 240 mg qday. I have noticed I'm still tachy 120's at times and up into the 150s.
The doctors were very concerned that my heart would become enlarged with the constant tachycardia, so they attempted several SA node ablations. I had three ablations done over about a years time. Eventually they did work, but they ended up ablating a little to much of the sinus node and my heart rate dropped profoundly to 30-40. So they ended up putting in a single chamber atrial pacemaker.
The reason for them is, ironically, to help prevent the heart from stopping, they are God's way of giving the heart's normal electrical points (SA Node and AV Node) a backup system! Believe it or not, you are fine in reference to these premature beats, so you are better off to try and just forget about them. Being pregnant, you are going to be having more heart 'issues' because your heart is working harder than normal to cover for your baby.
Because beta blockers slow down heart rate though, sometimes the rate can become so slow, or otherwise irritate the ventricles, that the ventricles themselves take over for the SA node (primary pacemaker) momentarily. This is infrequent as far as I know though, and is usually not considered an issue unless there is a history of heart block. I'm not a doctor though, just sharing my personal knowledge. Good luck!
the doctor I saw before the EP had said it was SA node tachycardia. The EP says it's Inappropriate Sinus Node Tachycardia. 6) Where would be the best hospital to go to/area of the US to go to, to get help with this? 7) When I was 16 I was told that I have a 2cm mass on my adrenal gland. It was never investigated despite my requests. (I've had my tachycardia for 6 years). The last 3 years, my hair has fallen out of my head by the masses. Could this tachycardia be caused by a pheochromocytoma?
The contractions are caused by an electrical signal that begins in an area of the heart called the sinoatrial node (also called the sinus node or SA node). The signal moves through the upper heart chambers (the atria) and tells the atria to contract. PSVT starts with events taking place above the lower heart chambers (ventricles). PSVT can be initiated in the SA node, in the upper heart chambers (atria), in the atrial conduction pathways, or other areas.
I had mine done last tuesday and prior to the procedure I was warned it may take a few times...mine is the sa node itself..i had chest pain and arm pain post which i was told take ibuprofen for..due to the irritaiton to the heart muscle and damage caused by the ablation itself..was extremely tired the first few days but slowly getting better...i will eventually have a pacemaker due to the fact its the sa node itself...im also 29 and was very active..
