Your pulse was slow because Atenolol is a beta blocker and beta blockers drop the heart rate. Your doc should have had you monitoring your hear rate.
Please be careful with the Lisinopril.
I am posting my lisinpril side effects after taking for a week and I really have none except the throat is sore and only slightly and not all the time and I get a little light headed when I stand sometimes. I have been drinking green tea on ice for comfort for the sore throat thing as green tea is a antiseptic and soothes the throat. The lisinipril seems to work for my blood pressure, it is staying in the 120/77 range but pulse is a little low yet, it is 51. This bp is working better for me than atenolol did. I had extreme slowing of my heart from atenolol after taking it for 5 years. It slowed my heart down and my pulse was only 41, all I wanted to do was sleep 24/7. I was like a zombie for a month and didn't know it was the atenolol as I take other meds I had to go to the dr and they did a ekg and told me my pulse was way too low and the Dr said he can't believe I was still walking. I had to immediately stop the atenolol and he started me on lisinipril 2 days later. It is a ace inhibitor and atenolol is a beta blocker. Each bp medication works differently for certain peoples different problems. I always check on drug interactions at http://www.drugs.com/drug_interactions.php here you can type in everything you take including herbs and vitamins and it tells you what drugs are interacting and what foods an drinks that you should not take. I will keep posted here on any ongoing interactions as I have not been taking this for long I may develop some more.
