high blood pressure
"My doctor gave me Losartan and I took it for 3 wks until I developed a 2nd degree heart block.  When I noticed my heart behaving oddly, I stopped taking the drug.  My heart appeared normal within 5 days, after having been admitted to the hospital.  I was told Losartan does not cause this but in researching it, I found that it does at times.  My heart was doing well for about 6 months after this, but then it happened again a few more times.  This last time, July 2016, I went to the ER and they found I had a 2nd Degree Heart Block Mobitz Type ll with Bradycardia. I was symptomatic with my legs feeling heavy & breathing harder after walking a short distance.  I was told I could have sudden death if I did not get a pace maker, which I now have."
