Pacemaker wires + heart valves + light headed.
Since my pacemaker 18 mths ago I have experienced constant light headedness + frequent mild nausea. Nothing has been found. I noticed on my oximeter that O2 levels have dropped from fairly constant 98/99% to 94/96%. The only thing left that I could think of was valve leakage in the paced side of my heart. Looking at my heart X rays I was surprised how thick the pacemaker wires were going thru the heart valves. Heart valves calcify as we age + any foreign object going thru them must cause leakage. Question-how significant is this leakage under pressure? What are the common wire diameters? What are the long term effects on the heart valves themselves with a wire shoved thru them?
