Beta blockers

[Heathbar]

I'm on a small dose of bisoprolol, 2.5 mg's. To be honest it doesn't help the pvc's. Is there a specific beta blocker that deals directly with supressing these pvc's. I've been on toprol as well with no positive results.

I am very sensitive to meds, too!  I can only take 12.5 mg of atenolol, it seems to take care of my NCS, but it's not enough for my IST.  (I say seems, because there is now a question about spells I have been having as to whether or not they are near syncope from NCS or another arrhythmia).  So, to help with the tachy I take verapamil.  I still have breakthru tachy, but I am not usually symptomatic now.  

Also, the nice thing about verapamil is calcium channel blockers are sometimes used for Raynaud's, which I have.  When I 1st started it my hands and ft would get uncomfortably warm, but it was better than cold.  Now, they are better than they were, but still on the cold side.

Capsicum, I hear, is good for Raynaud's and if you have it pretty bad you can ask your dr. for nitro cream.

im 18, 6 monthes after i gave birth to my son i was ablated for psvt and avnrt in nov 2002. in march 2003 i developed pvc's. because i never had a pvc before the ablation i think the ablation caused the pvc's. i have pvc's all day everday but im cured of all my other arrythmias. i do experience sinus tachycardia(resting hr about 100) for some reason i had it for monthes then recently it went away. i get a fast heart rate upon standing, have low blood pressure and fatigue ever since i woke up from the ablation. in your case i would say go for it because you have the svt everyday. my psvt went up to 300 one time in the er....but i only had it once every 2 weeks(usually 250bpm for 5 hrs). well good luck let me know how it goes.

I have had SVTs & PVCs since the 80's, I am 29 yr old F, have gone to ER many times for SVT/ doc put me on Toprol XL 50 mg., I started meds 1/30/04 (I waited so long because I was more afraid of the meds than condition until recently when 1) I learned SVT can lead to clotting & 2) I started suffering horrible chest pain w/them).  (Noraml echo.)  I've had more problems ever w/the meds, I am very sensative to meds.  I have headaches every day, swelling in my left leg & left arm, pinching/cramping in my arms/legs, chest tightness, fatigue.  Doc said to take 1/2 dosage (25 mg), the decrease made me have SVT EVERY DAY, now i'm having PVCs all the time that feel different, ie..I feel like i'm always starving for air, with a cool rush through my arms like anesthesia or something.  Due to increase in SVT my doc said to go back to 50 mg. Toprol XL.  All day today i've felt like my head would bust, also having chest tightness, PVC's, pain in extremities, BUT it also feels like my heart & blood flow just STOPS all of the sudden & I get very panicky. I am scheduled for thallium stress test 3/30 & ablation 4/7.  Should I have these procedures done?  It has been almost 2 months since taking meds, why would they make me worse?

MEANT TO SAY CLOSING NOT CLODING. GREAT NOW I CANT SPELL.

My pvc's come with no rhyme or reason it seems. My heart rate isnt too fast when i have them, thats for sure. Seems to happen more when i'm resting. Sometimes my throat feels like it's cloding as well, mabey its the anxiety thing. Not taking anything for anxiety mabey i should.

I must say that I am not a doctor, but I must agree with everthing I have seen you posted thus far.

Beta blockers mostly only work for person with PVCs that their PVCs are triggered or/and aggravated by an elevated heartrate.

Sometimes by reducing the force of contraction the beat after the PVC is less noticable , thus relieving uncomfortable symptoms associated with PVCs.

Sometimes beta blockers slow the heartrate in excess and thus aggravate or cause more PVCs because the ventricles take over momentarily from heart natural pacemaker, thus triggering more PVCs.

It is my understanding this why some well trained conditioned athletes develop induced conditioned PVC syndrome, because their heartrates have become slower due to exercise and conditioning thus causing a slow heart rate in which the ventricles fire prematurely to make up for the delayed response of the heart's natural pacemaker.

I could be completely wrong , but this is my understanding also.
