What is a heart fibulator?
it's actually called a cardiac defibrillator. it is a device that is implanted into the chest wall and has a wire that goes in to 1 or 2 of the lobes of the heart (depending on the type) it is for people who have been diagnosed with ventricular fibrillation, a deadly cardiac rhythm. this device detects when the heart goes into ventricular fibrillation and will shock the heart causing it to stop briefly and restart. this triggers the heart to "re-set" and will hopefully allow the natural heart rhythm (also known as Normal Sinus Rhythm) to take over. without this device, they would die. Only a doctor would be able to tell if the person can resume every activity depending on the severity of the condition and how often the defibrillator "fires" microwaves and cell phones have no effect on defibrillators. Hope this helps.
How do surgeons develop steady hands outside of the OR?
Not sure that everyone doesn't actually have the "steadiness" already. What we do have is the ability to have impeccable hand eye control. When we tell our hands "go left 1mm" they go left only 1mm and not 2mm or up 1mm.There is nothing to do to practice but the ability to see the difference between correct and not correct comes with time in grade and that is why residencies in the surgical specialties take so many years. Especially with more and more super specialties being created the actual need for multiple years in terms of knowledge is not the issue but the time doing the various services under supervision is necessaryYears ago using one example the Orthopedic specialties one would become on and either did spine or limb Orthopedics now the specialty is broken to hand and wrist and shoulder and elbow and that is JUST the arm. The legs have similar breakdowns.The key to successful hand function is doing it over and over and knowing when doing it is acceptable and when it is not and that can only happen under supervision and with repetition Thanks for the A2A I hope this helpedDr D
From where "automaticity" of heart came?
from cells that act like a bypass, those nodes r everywhere in the heart; they generate they own action potential by Ca++, K+, Na+. This potential is what makes the heart beat... systole and diastole. They dont need any stimulation from parasimpatic or simpatic systems... they activate by themselves.
Do doctors in India only marry doctors?I like this girl a lot, but I am an engineer and she's pursuing medicine. Plus we both live in different cities. How should I approach her? Do they think other people are not intellectually of their level?
Well.. I can tell you a few things.. There are much more male doctors than female doctors. While 99.999% female doctors get married to other doctors, male doctors are not so lucky. Unless it's a college love... A female doctor if only mbbs will marry an md / ms guy only. And an md / ms female doctor will marry a dm / mch guy only. That's the rule.. So unless she gets a guy according to this doctor - caste system, you have a good chance. Doctor duties and responsibilities are notorious, so if you ever marry a doctor girl, be prepared for that. Also almost.. No not almost but each and every doctor in india regrets to have ever deciding to join the Medical profession until they are 35 or 40. So, if your future girlfriend or wife is a doctor, please try not reminding her of her profession as much as possible,she will be grateful for that. She may initially pretend to be high nosed because of her profession, but trust me that's just a defence mechanism. It will go away once she starts trusting you.
Do doctors have to work long hours no matter what?
The answer, as in a lot of things in life, is that it depends. Depends on the specialty of the doctor, whether they want to be busy, where they work and how their contract is set up. I’m a primary care doc and hospitalist. I did vacation coverage for a clinic once where I saw maybe 0–2 people a day from 9–5pm for a week. They paid me an hourly rate with an 8 hour guarantee, so it didn’t matter that I barely worked I still got paid and I could do whatever I wanted as long as I sat in the office for 8 hours. Dermatologists also have regular office hours like that: 9–5, 40 hours a week and they do very well.At the other end of the spectrum you have surgeons who frequently work long hours and may have lengthy operations and get called back in the middle of the night when they are covering their colleagues. The worst situation would be a surgeon who didn’t have any colleagues to cover for him, he would be “on call” for emergencies all day, every weekend and every night - some crazy people actually do this, especially in smaller towns - albeit in those smaller places its more doable because they may not get called in as often.As a temp hospitalist I’m scheduled 12 hours a day, but often work 3–6 hours depending on how busy it is. I get paid an hourly rate for the 12 hours. So although I might be scheduled for 80+ hours a week I might only actually work less than 40. Still I am on call the rest of the time to answer nurses questions and come back for emergencies - there is some low level stress involved in that.If I was a permanent employee in a clinic I could either have a contract giving me a fixed sum a year, or a fixed sum plus a productivity bonus, or compensation entirely based on my productivity. In the productivity scenarios I would be incentivized to see more patients to make more money. So some people try to cram those extra patients into an 8 hour day, seeing a patient every 7 minutes and others might just work longer hours and weekends.For some specialties (eg. surgery, OBGYN) in some locations it’s very hard to work reasonable hours. Other specialties (eg. derm, radiology) in other locations are more of a cake walk. If you’re wondering about a particular field and know which city you want to live in you should ask people who live and work there what their lives are like.
What are all the types of doctors and what do they do?
Anesthesiologists - An anesthesiologist is the one who 'puts you out' for surgery and who monitors the patient's vitals. Dermatologists - If you have a skin problem, go see a dermatologist. As a dermatologist you'll diagnose and treat things like psoriasis, eczema, skin cancer, scabies, and acne. Emergency Medicine Doctors - If you have ever watched the television show ER, then you have a rough idea as to what emergency medicine doctors do. They work in a hospital's emergency room, responding to myriad medical conditions. Family Practice Doctors or General Practitioners - As a family doctor you'll have regular patients, whole families, who see you for referrals to specialists, for sprained ankles, skin problems, you name it. Neurologists - If the brain and central nervous system are fascinating to you, then become a neurologist. In this field you may be treating spinal cord injuries or deep brain injuries. Obstetricians/Gynecologists - As an OB/GYN you could work in a hospital, private practice, or both. Your patients will be women. Every day you will be consulting on pregnancies and childbirth related issues as well as other women's healthcare issues. Oncologists - Treating cancer is what an oncologist does. Oncologists may end up specializing in the treatment of specific cancers. Pediatricians - Do you like working with and being around kids? If so, then become a pediatrician. It's a very rewarding job, and you'll often have a steady, devoted clientele. Plastic Surgeons - Are you the next Dr. 90210? As a plastic or cosmetic surgeon your job will be extremely varied, from doing breast augmentations and facelifts to helping burn victims. Psychiatry - Unlike psychologists, a psychiatrist is a medical doctor who has graduated from medical school and can prescribe medications. You will be working with people who suffer from a variety of mental illnesses, and could be located in a hospital's psychiatric ward or in private practice, or both. Urologists - Ah, the dreaded bladder infection! Time to go see your family doctor, who might refer you to a urologist, a type of doctor specializing in ailments related to the urinary tract. Best, Ali
