i'm sorry to hear this and hope you're under a doctor's care. i'm assuming you are since you mention pvcs. one thing that can cause a drop in blood pressure is taking too high a dose of blood pressure medication. as with most medications anti-hypertensives need to be evaluated over time to make sure the dosage is still correct. sometimes as we age we need a lower dosage of medications in general simply due to our aging 'machinery. ' the liver and kidneys may not process (metabolize) drugs as thoroughly as we get older for example. however you should never adjust your own blood pressure medication dosage. only make adjustments when instructed to do so by a doctor. your heart issues also could cause your blood pressure to drop. whenever the heart isn't pumping correctly it can affect the pressure in the veins and arteries. in effect when the ventricles contract prematurely (pvcs) it means they're out of sync. they're not pushing as much blood into your system as they should. thus your blood pressure may be reduced. you should check with your doctor about how to handle the low blood pressure issue. the situation can be handled in multiple ways and only your cardiologist can advise you how to proceed. wishing you well!
why would someone with high blood pressure have their blood pressure get dangerously low? . i have had high blood pressure for 22 years. suddenly my blood pressure is running extremely low. also started having pvcs.
