Relationship between pulmonary embolism (PE) and atrial fibrillation (AF)

If PE and AF occur together it is most likely that the PE is the cause of the AF.

The mechanism of the AF is said to be acute right ventricular dilatation with "strain" due to the embolus in the pulmonary circulation creating backpressure into the right ventricle.

If a patient presents with unexplained AF, look for an accompanying PE as the cause.

It is postulated that AF can cause PE if a clot originates in the right atrium rather than the left, but this is less common than clots originating from the right ventricle and more studies need to be done in this area.

Hello,

Healthline just designed a virtual guide of how atrial fibrillation affects the body. You can see the infographic here: http://www.healthline.com/health/atrial-fibrillation/effects-on-body

This is valuable med-reviewed information that can help a person understand the effects of afib of their body. I thought this would be of interest to your audience, and I’m writing to see if you would include this as a resource on your page: http://didiaskforitstat.blogspot.com/2007/07/relationship-between-pulmonary-embolism.html

If you do not believe this would be a good fit for a resource on your site, even sharing this on your social communities would be a great alternative to help get the word out.

Thanks so much for taking the time to review. Please let me know your thoughts and if I can answer any questions for you.

All the best,

dr itua healing herbs the worst moment has passed, however, it is true that there are more improvements than before… due to the growing number of people living with hiv in the state of nevada. How could they stigmatize them all? then everything becomes a little easier and we begin to share everything... we also begin to invite each other and visit each other in community. You know, it's been six years since I started taking antiretroviral drugs… however, regardless of the problems I faced, the worst moment was when my mother evicted me from the family home, my father rented me a small room. but my mother and my brothers believed that having hiv was my fault and that I deserved to be punished… I also considered myself unworthy and hopeless… but I have a son and eventually I convinced myself to live for my son reason. my mother didn't know anything [about hiv]. she didn't understand anything. You know why? she did not have [the opportunity] to leave the house and communicate with society. however, my father interacts with the community. I know that his friends are mature and dignified in Africa America. so he has a better understanding than her. my father came to call me one sad day sitting on my sofa about a friend of his from africa who introduced him to dr itua herbal cure in africa in which he advised me that we should buy his herbal medicine to cure my hiv, so we did and dr itua prescribed me that i should take the herbal medicine for two weeks to cure myself, although we were very curious about the whole thing, i finished the herbal medicine as he advised, then he told me to visit the nearest clinic for a check up i did and now i am totally cured of hiv my father was my rock and me and my family are now happy together too dr itua has been helpful in my community since he cured my hiv and tinnitus so why do i quit my story here today is to get someone here to hope in god and never give up no matter what situation you are facing especially during this pandemic season which has really taught us all how we should s help each other and appreciate each other. dr itua cures the following diseases... herpes, liver cancer, throat cancer, leukemia. , alzheimer's disease, chronic diarrhea, cop, parkinson's, als, infectious mononucleosis adrenocortical carcinoma. bowel cancer, uterine cancer, fibroid, bladder cancer, HIV, esophageal cancer, gallbladder cancer, kidney cancer, HPV, lung cancer, melanoma, mesothelioma, multiple myeloma, oral cancer, sinus cancer, hepatitis a, b/c, skin cancer, soft tissue sarcoma, spinal cancer, stomach cancer, vaginal cancer, tinnitus, vulvar cancer, testicular cancer, thyroid cancer. you can contact dritua herbal center at email: drituaherbalcenter@gmail.com .www.drituaherbalcenter.com.
