I am a 44 year old healthy female. In Sept. I had a lithotripsy procedure (blasting of kidney stones). Apparently while I was under sedation, my heart rate went up and down, as low as 30 bpm to 140 bpm. A nurse told me that she asked the urologist "What organ he was near when this was happening." After I came out of sedation, I was asked how my chest felt. I had some pressure so they admitted me overnight for testing. Xray, doppler, came back normal; however i was told that there were EKG changes. After I was released I was put on a 30-day monitor. My heart rate soared daily to over 200 bpm on and off throughout the day. I was told I had two options, medication for the remainder of my life or a cardiac ablation. I opted for the ablation due to the side-effects and long term effects of the medication. My question is, could the lithotripsy have caused this SVT, the sedation, or could this have been a pre-existing condition that was brought on by this procedure? Thank you.
