A) They are narrow electrocardiographic wave (QRS) complexes that are preceded by P waves.
B) In most cases, they disappear with exercise.
C) They are treated with type IC antiarrhythmics.
D) They may represent a risk for sudden death in healthy patients.
E) Caffeine use is not associated with PVCs
Answer: B ( In most cases, they disappear with exercise.)
Discussion: Premature ventricular complexes (PVCs) are abnormal ventricular beats that are characterized by wide QRS complexes, which are usually not preceded by P waves.
In patients with normal hearts, PVCs usually disappear with exercise. If the patient remains asymptomatic and there is no organic heart disease, no further treatment is necessary.
If PVCs are frequent, electrolyte abnormalities and heart disease should be excluded. Patients with frequent,
repetitive, or multiform PVCs and underlying heart disease are at increased risk for sudden death because of cardiac arrhythmia (particularly ventricular fibrillation). Without underlying cardiac disease, bigeminy and trigeminy are considered benign rhythms. Treatment of PVCs is controversial but should be reserved for symptomatic patients. If MVP, hypertrophic obstructive cardiomyopathy, prolonged QT interval, LVH, or CAD is present, a trial of B blockers can be used. Types IA (quinidine, procainamide) and IB (lidocaine, mexiletine) antiarrhythmic agents may be used; however, they are associated with a high incidence of side effects and can make the arrhythmias worse. Type IC agents (flecainide, propafenone) should not be used because of their potential for increased mortality rates. Elimination of exogenous catecholamines, sympathomimetic amines, alcohol, and caffeine may decrease symptoms. In general, antiarrhythmic drug therapy is rarely necessary.
Nice blog
ReplyDeleteHave been totally convinced that HIV,and many others dangerous diseases can be best cured using the Herbal Medicine. Dr.Akpu the great and powerful herbalist cured me with his Herbal remedy. I'm Linda,15 years from Texas. I was born with HIV. I lost parents at my teenager age when I was 4th. I had to grew up with my mum only Sister, whom I loved so much. She was so worried about my life as my condition was her mature problem in life. I had taken lots of antiviral treatment to get ride of the virus not believing what there said HIV has no cure. I was on the internet when i came across blogs of testimony about a lady who where cured of a 7 years diagnose of Herpes by this powerful Herbalist, Dr.Akpu.I wrote down his mail @ Dr.akpupowerherbscenter@gmail.com
I told my Aunt,luckily it was the same Dr,we where referred to few months back by my pastor in church whom members have being testifying about of his cure We did contacted him and explained my problem to him.He prepared the medicine and sent to me with details of how to use and apply. After a while, I began to feel more strong than never before, I felt so lucky and happy when my Doctor congratulated me that he could found no HIV virus again in me. I knew I was free cos my body was so strong. His herbal medicine should have saved my parents life, i said!

Is the solution
ReplyDeleteThe worst time has passed”However, it is true that there are more improvements than before...because of the rising numbers of people living with HIV in the state of Nevada. How could they stigmatize all of them? Therefore everything becomes a little easier and we start to share everything... We also started to invite and visit each other in a community. You know, it is six years since I started taking antiretroviral drugs...Yet whatever problems I face, the worst time has passed
When I was evicted from the family home by my mother, my father rented a small room for me. But my mother and brothers believed that having HIV was my own fault – and that I deserved to be punished...I also considered myself unworthy and without hope... But I have a child and eventually I convinced myself to live for my child’s sake.
My mother knew nothing [about HIV]. She didn’t understand anything. Do you know why? She didn’t have [the chance] to go out of the house and communicate with society. However, my father does interact with the community. I know his friends are mature and dignified in africa america. So he has a better understanding than her.
My father came call me on a sadfull day sitting on my couch about a friend of his from africa who introduce him to Dr Itua herbal cure in africa in which he advise we should purchase his herbal medicine to cure my hiv so we did and Dr Itua prescribed I should drink the herbal medicine for two weeks to cure although we were so curious about the whole thing ,I finished the herbal medicine like he advised then he talked to me to visit my nearest clinic for check up I did and now I'm totally cured from Hiv my father was my rock and I and my family are now happy together also Dr Itua has be helpful in my community ever since he cure my Hiv so why I'm leaving my story on here today is to reach out someone out here to hope on God and never give up no matter the situation you that you are facing especially through this pandemic seasons which has really taught us all on how we should be helpful to each other and cherish one another.
