My son had Kawasaki at age 3, and at age 5 was diagnosed with "benign" PVCs. Benign is in quotes, because when they are really bad, he feels really bad and has zero energy- he can't function at all. His NP thought it was so bizarre that he suddenly developed PVCs with no history of murmur. He is 8 now, and had an episode today. He felt so bad that he sat down in the middle of the CVS parking lot because he felt that he just could not walk any further (we were parked about 35 feet from the door). I have found no correlation acknowledged on the world wide web between Kawasaki and PVCs, but we can't help but wonder. Tomorrow we will begin our search for a new pediatric cardiologist for a 2nd opinion.
Interesting! My daughter also had Kawasaki Syndrome at age 3 and she is now suffering PVCs. They have her on a monitor to see what the best course of treatment might be. She is now 33. I, too, wonder if there is a connection with the Kawasaki's.
So many people get PVCs that have perfectly normal hearts. I get them a lot, I have a normal heart. My LVEF is 74% which makes for one strong ticker.
I've gotten them since I was a kid though very rare at the time. As I got older they became a bit more frequent. I'm very aware of my body and notice them. It wasn't until they were caught one day on a stress test that I found out exactly what it was. Most days I hardly get any. Some days I get a lot. All my tests, and I've had many, are normal. I started testing when I was 35 due to significant heart disease in my family (CAD).
My grandmother had PVCs her whole life. She would walk to the ER 3 or 4 times a year she would get so scared. She recently passed away, at 95, and it wasn't her heart that got her.
Anyways, your question is tough to answer. Anything is possible. Statistically speaking they are probably the run-of-the-mill benign PVCs that most people get. Some feel them, some don't. But who knows without running some tests.
She should probably get an EKG, stress test, and an echo just to start off then go from there.
Things that will be prognostic about her PVCs are the frequency, where they are coming from in her heart, groupings, patterns, timing.... other questions I would want to know is if anything enhances them or in other words brings them on more frequently like exercise, at rest, positional....that sort of info can help.
Doing a quick search for Kawasaki's + Heart + PVCs on google didn't turn up any info at all. My thinking is that if this was a common issue I'd see more results.
