I really don't know if this has any connection but here goes. I am 60 years old with no significant medical issues. My blood pressure has been creeping up over the past few years. Because of my job (professional pilot), I addressed the blood pressure issue with my family doctor and she prescribed Lisinopril. I was on the medication for a little over 3 months when all of a sudden with no warning my heart rate jumped to 185 and remained there for almost 2 hours. I underwent an angiogram (no significant blockage) and an echocardiogram (negative). I have an appointment with a Cardiologist in two weeks to continue follow-up with a stress test and possible electrophysiology study. Attempting to figure out what happened I started looking at what in my life had changed in the past few months. To my surprise I ran across this information on Lisinopril (rat poison).
