Earlier this week I went to my EP on the first day the office opened to patients since the Covid lockdown. My EKG revealed changes that concerned him, comparing it to the last EKG Feb 21, before discharge from the hospital. I have an ICD and am paced in the atrium 99% due to SSS and paced in the ventricle 30%. I had an ablation Feb 20 for atrial tachycardia and atrial flutter (over 110 areas ablated) and was doing fairly well, but it changed around March 23, texting my EP regarding extreme tiredness, swelling all over my body, and my arrhythmias had returned. I did not tell him how sick I was......but as months went by and broader Covid symptoms were revealed, I was pretty sure I had Covid. I had Covid testing over the last few weeks and both tests came back negative. My labwork revealed inflammation and elevated white blood cell count, so the EP is suspecting pericarditis. He has started me on oral med for pericarditis and I will see him in a couple of weeks, and I am sending Carelink transmissions 2x/week. I had 75 atrial tach events ranging from 140s - 160s, sometimes lasting for up to 6 hours, since Monday's appt. Can pericarditis spread to the ICD and leads? I am looking for opinions regarding pericarditis. He told me at the appt. several times I must let him know when I am sick with anything, no matter how minor I think it is. He's an amazing EP and person, and I've been going to him for 21 years. Any comments would be appreciated. I'm pretty worried, as I am noticing my arrhythmias and the way I am feeling is worsening.
