Arrhythmia and Atenolol

[Lisa Bowman]

Hi, I have been given a prescription of Atenolol to treat my arrhythmia.  Since the package insert for the drug does not list arrhythmia as one of its indications, I would like to know if this is a common AND effective use of Atenolol.

Thank you.

Dear Lisa,



Atenolol is very safe and effective medication to decrease PVC's and arrhythmias.  It is commonly used in this case.

I am curently taking atenolol for a severe heart arrythmia and it is working great.  Ive never felt better.  So to answer your question it must be effective at least in my case!!

Thank you for your reply.  It makes me feel better knowing that others have had a positive experience with Atenolol.

I have SVT and have taken atenolol for almost two years.  The results have been good but there was an adjustment period for the dosage.  There are two side effects that I notice which are a little breathlessness when climbing stairs and vivid dreams.  Otherwise, everything is okay. Hope this information helps.

Atenol user for 10 years.  Keeps that heart rate down.  Don't know what I'd do without it.  Tachy from anxiety/panic attacks was my diagnosis for usage.

Dear Anne,



Thanks for sharing your experiences.

Lisa,



I have been taking Atenolol for about a year now since I started having Atrial Fibrilation attacks after heavy exercise and eating certain food, especially pizza. It has done a good job of controlling it. I have only had 2 minor attacks since I have been taking it: 1 after playing pickleball and I forgot to take it the day before, but it only lasted about an hour, and 1 in the morning for about 30 minutes.



I hope it works as well for you. It looks like my rythym problems are the least of my worries now since I have a ASD and some Tri valve leakage and they are recommending surgery to close the hole and fix the valve. Wish me luck!

Here is a brief explanation on how your medication is working to treat your tachycardia. Your heart contains receptors called beta-1 receptors. When beta-1 receptors are stimulated the heartrate increases, you have stronger heart contractions and you have a greater increase in output of the heart (blood) to the rest of your body. Atenolol(Tenormin) is a beta-1 receptor blocker. It binds to this receptor and "blocks" the actions that I just described. So as a result, you get a decrease in heartrate (tachycardia) and your heart doesn't have to work as hard to get blood to the rest of your body. I hope this kind of helps you understand the way your medication is working

Although it is not indicated in the product insert, the main action of Atenolol and other beta 1 blockers is to lower the heart rate. Also, this is one of the mechanism these drugs were designed in controlling hypertension.

Thank you to all for sharing your experiences.  Beta blockers are great cardiac drugs.
