Has anyone ever had extreme pacs out of the blue? I have an implantable loop recorder so I was able to catch a lot of what was doing on. They told me they saw frequent PACS and there were a few episodes that were so long my EPs office thought for a moment I had afib- two episodes that lasted for SIX minutes each that’s how close together these PACs were! This has been happening on and off for two days. In the past cardiac wise I have been diagnosed with SVT, non sustained VTach (ventricular tachycardia- which is not the same as SVT *people seem to get these confused often) as well as atrial tachycardia, inappropriate sinus tach and POTS. I do tend to get PVCs and PACs. My PACs have never been in terribly long runs. I have never had an episode of AFib either.
What concerned me is the out of the blue nature of this. It hit me out of no where. and I have never experienced anything like it. I was so concerned because my heart was so out of sorts and I was so terrified I went to the ER. Where they put me on the monitors for a few hours. But as we know most ER visits are useless! My heart was all over the place. I had frequent PACs, I had a few Pvc pairs, a small run (3 beats) of NSVT, irregular heartbeat, multiform PVCs, a multifocial PVC as well tachycardia. My rhythms for the most part stayed either sinus or sv rhythm except a few times unknown origins came up or it alerted irregular heartbeat. Everything regarding my blood work was normal except my TSH level was at 12.9 which is hypothyroidism. I have never had an abnormal TSH but for years I have had antibodies and been diagnosed hashimotos disease. The endocrinologist swears that hypothyroid doesn’t cause arrhythmias especially what I’m dealing with while my EP disagrees. Has anyone else ever experienced this or something similar? My EP told me they have no idea why this is happening all of a sudden but we are monitoring it. In addition to my loop recorder they put a 24 hour holter on to see what’s up.
I honestly can’t believe how terrifying long runs of PACs can be and it’s hard to know when it happens if it’s the PACs or if it could be PVCs! Both feel similar. Hearts shouldn’t beat out of sync and when they do you have no idea how much trouble you could be in. Emotionally this is taking a toll.
