i have a pacemaker and am having longer, more frequent episodes of pvc s, apparently every other beat. i can always feel it when it comes on, fluttery, thump heartbeats, increased pressure in my head, ache at base of skull, fuzzy thinking, fatigue. pacemaker checks out aok. am taking atenolol and irbesartin and metformin. pacemaker is 4 years old - these episodes came on within last year. before that pacemaker kicked in every time my heart rate dropped to 60, usually when i was at rest or lying down. now they occur even when i am active and my heart rate is elevated. i have some mitral valve issues. might a change in meds relieve or lessen the pvcs?
