Maybe... I am Caucasion, slim build ,5 8 and 145lbs ,no huge belly,(except after a too large meal....) age 67. H/O CABG X 3... 27 years out. Asymptomatic , Indolent Follicular B Cell Lymphoma X 8 years with H/O 10cm Lymph node mass of Mesentary. No past treatment course needed. Otherwise healthy. I workout moderately X 3 per week. I seem to be experiencing what might be PVC s( I can feel the repolarization pause and a cough) or possibly PAC s with aberrant beats up to 6 times per minute..but only on occasion. Maybe occurring more when I am a bit tired or sitting down in the car or a chair..not noticed as much when standing. I am noticing that when I take my pants off (33 waist is usually too loose , some 32 s are tighter than they should be at times after a meal) (normal 32 waist) it seems to be resolved. It sounds silly but my thinking is that Baroreceptors might be reacting to pressure on the abdominal Aorta by the pressure on the Mesenteric Hypertrophic Node.... Sounds far fetched although I am seriously thinking that it is the cause..Holter has shown very little...Occasional PAC s were noted. Just want to hear what you think. It s pretty obvious to me that if it stops when the pressure is released it must be the problem.Have you seen this before ? Thank you PSF ..DPM , PA-C (Oncology)
