Hello, A late answer I suppose... Your blood pressure seems to be uncontrolled. The best way to help your doctor in similar situations is to measure your blood pressure every morning and afternoon for a week or so and record the measurements. Your doctor will find your records very helpful. The irregular rhythm needs immediate clarification though. It could be just a few innocent systolic but I could also be atrial fibrillation or other types of significant arrhythmias. I mentioned atrial fibrillation because it is fairly common in individuals with uncontrolled blood pressure. You should discuss your problems with your doctor regarding lisinopril side effects and perhaps choose an alternative regimen. I hope I ve helped! You can contact me again if you d like any clarification or further information. Kind regards!
