as other pacemaker types
206754
without a pacemaker, such as an intermittent, the heart will continue to go into constant dysrythmia or atrial, ventricular, or sinus fibrillation. this makes it to where the hearts effectiveness(cardiac output) is decreased to nearly if not full asystole(without constriction) and blood will not flow through the body providing oxygen to all the tissues, including "the brain" and you will die due to ischemia- lack of oxygen. the pacemaker "paces" the heart keeping it under control like a kid on Ritalin

There's all different forms of irregular heart beat, and a doctor can usually tell from what sort of irregularity whether or not it is very serious.  I have an irregular heart beat myself, but I understand it is not a particularly dangerous kind.  I ought to lose weight, of course I know that, but it's not more than a somewhat increased risk of heart attack.\n\nBut some kinds can be a warning of much worse stuff, so it would clearly pay to have your doctor listen to it, and take whatever tests he really needs.  Good luck.

Also known as SVTs, it describes a very rapid heart rate. It would be helpful to know the underlying rhythm (ie: atrial flutter, atrial tachycardia, etc...) If you find out, post this question again. It would be helpful to know a few other things about you, so I'll have to give a broad answer. The heart is unique tissue that beats when it receives electrical impulses (you may have seen actors who pose as "dead patients" on t.v. get "shocked" in the ER with electricity to help their hearts beat again). With SVTs, a part of your heart gets "excited" and starts to shoot off it's own electrical impulses, which can cause the heart to beat out of rhythm, and very fast. You should see a cardiologist and have a few tests such as a 12-Lead EKG, 2d echo, holter monitor, blood & thyroid tests, and possibly a stress test. Many young females get SVTs, which is usually harmless and do not cause any longterm problems. These cases can be treated with simple lifestyle modifications that can minimize attacks (such as sleeping better, reducing stress and eliminating caffeine products). Patients can do Valsalva manuevers to stop SVTs. As far as alternative, homeopathic, etc... there are no products that have shown evidence in successfully treating SVTs. If you ever find that your SVTs won't stop, you may get dizzy, get chest pain and your cardiac output will fall and you can pass out. Have someone dip your face/head in a bucket of ice-cold water (the mammalian diving reflex) and call 911. Medications, ablation, cardioversion, etc... are reserved for advanced cases. These patients may be older or have other cardiac issues going on. Or they can get SVTs before or after a heart attack due to changes that occurs in a part of the heart called the "Atrium". I hope I was able to answer some of your questions...

i guess A, U and mu law are used for pulse code modulation. i have no idea that these are different for different countries or country specific. u can try google.

yes, males have slightly higher volumes in their hearts and a slightly lower pulse rate. Sorry no sources, ask a nurse.

I also have MVP.  In my case, the person doing the ECG showed me the fault.  I was able to see the valve failing and allowing blood to flow in the wrong direction.  I'd get another ECG done and request to see the result.  It should be easy as it's just a matter of having them point it out to you on the screen.  I wish you all the best!

A Taser will not disrupt a pacemaker.  The amps are too low to affect the internal systems of the body.  Tasers are no more harmful to the body than an really bad static shock.  Pacemakers are designed to be protected from such electrical impulses.

this is not true.  not at all.  my source is that i am a urologist, and i do not see much dextrocardia, but i do see it hanging on boths sides quite often.

There Sach's organ has a stack of electroplaques, which acts somewhat as a stack of battery plates. There evolutionary history is not know to me.

A pacemaker cell must have a long life (you don't want to have to open someone back up every .week to replace the batteries) and it has to be corrosion resistant.

Beat, pace, tempo, time, pulse...

Please, that should be in your books. Ventricular depolarization is represented by the QRS complex, and ATRIAL depolarization, by the P wave

It depends upon the type of disease.... generally for cardiac diseases, the most frequent treatments involve medications for blood pressure....  if someone has previously suffered a heart attack, a bypass and grafting are often done...  a pacemaker may be installe dto regualte heart rate and to ease the stress put on the myocardial tissues...\n\nthere are a multitude of respitory (lung) diseases as well... most common of course being asthma... but for any ailment affecting the lungs a common treatment is an inhaled medication that opens up the small vessels within the brochials... albuterol and combivent are common meds for such... a nebulizer may be used instead of an inhaler which acts in much the same fasion but adds a bit of moisture...\n\nto best answer you question however i would suggest that you refine your question to specific cardiovascular diseases

Not really, although it can tend to run in families. It is something people are born with. Very basically, it happens when a heart has an extra electrical pathway which at times causes a rapid heart rate. It sometimes can be serious, so if you haven't seen an electrophysiologist, find one soon. \nMore information is available at the Heart Rhythm Society website.\nGood Luck :>)

i have delt with thousands of patients with a slow heart rate(bradycardia) and it most cases it causes no inconvenience to the person life style or health,, there is simple medication available that will encourage the heart to pump at a normal rate..\na pace maker is a last resort for most patients and usually for the over forties..\nhaving said that a lot depends on what is causing the problem and how slow is the heartbeat.... a heart beat of 60-80 pm is normal for a adult at rest but some athletic people have a heart rate of 40 bpm at rest\nthe heart is a complex organ and has many safety features built into it,, the initial beat comes from the s.a node at the top of the right atrium and sends a signal via the punjibe fibres to encourage the ventricles (lower heart chambers)to contract and pump the blood through the body,, however if the sa. node fails for any reason the heart can fire of the signal to beat at two lower locations and get the same result,, poss this is where your friends missing beat comes into play,, im sure her doctor will do what is required and you try not to worry about your friend im sure she will be fine  ... keep smiling
