Can you explain the different components of ECG report?

Can you explain the different components of ECG report?

A lot!: For a cardiologist, an EKG can give information about the rate, the rhythm, whether there are signs of a congenital abnormality, signs of a heart attach or blocked artery, the thickness of the heart muscle, previous heart attack, and more. In experienced hands, an EKG can tell an incredible amount of information. ...Read more

Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

What kinds of things are considered artifacts that would effect a heart monitor and what's seen on the screen for the heart rate?

What kinds of things are considered artifacts that would effect a heart monitor and what's seen on the screen for the heart rate?

Artifacts : Any source of electrical input other than the signal coming from the heart can cause artifact. Examples are skin contact, electrical line interference, poor electrode contact, external current induction, electrical line flux and others. ...Read more

Can you explain the different grades of spondylolisthesis?

Can you explain the different grades of  spondylolisthesis?

Grading: Defined by how much the bone has shifted (translated) compared with the bone next to it. Grade 1- 0-25% translation, 2-25-50% translation, 3-50-75% translation, 4-75-100% translation. Greater than 100% is called spondyloptosis. ...Read more

When asked to compare two US of thyroid what kinds of information should we expect to see in the comparison. What specifically should be compared.

When asked to compare two US of thyroid what kinds of information should we expect to see in the comparison.  What specifically should be compared.

Changes in nodules: Thyroid US is usually done when you have enlarged thyroid (goiter) or nodule that can be felt. There are often other nodules within the thyroid that can not be felt and US can show them. We usually do a second US if a biopsy was done and definitely if non-suspicious nodules on first US to look for growth of nodules or development of suspicious characteristics both of which are reasons for biopsy. ...Read more

Identical twins have the same DNA sequence, then how would you explain the different patches of sweat glands, can you explain?

Identical twins have the same DNA sequence, then how would you explain the different patches of sweat glands, can you explain?

We're complicated: The twins share the same DNA sequence but going from a fertilized egg to splitting into multiple cells to form a human can be influenced by several factors that can lead to individual differences. I found this article very helpful in answering your question. http://multiples.about.com/od/funfacts/a/differenttwins.htm ...Read more

Can you please explain the function of prostate-specific antigen in normal cells?

Can you please explain the function of prostate-specific antigen in normal cells?

See answer: Prostate specific antigen (psa) is an enzyme which is secreted by the prostate gland and appears to play a role in the liquefaction of semen. Thus it has more of an "exocrine" function vs and endocrine function which imply a role in the physiologic or cellular processes of the body itself. ...Read more

Can you explain why there are "crossovers" of characteristics among the different types of eds?

Can you explain why there are "crossovers" of characteristics among the different types of eds?

Collagen: Eds has many different types. In most of its forms, the defect involves some aspect of collagen. Collagen is one of the basic building blocks of connective tissue which is found in all organs, joints and blood vessels. Depending on the exact type of genetic defect, and becasue collagen is found everywhere, there is cross-over in the types of eds with similar manifestations. ...Read more

Can you explain to me the primary and secondary immune response in terms of speed and number of antibodies produced?

Can you explain to me the primary and secondary immune response in terms of speed and number of antibodies produced?

Immunity: Very broad subject but the primary response is slower and takes time to make antibody to foreign particles. Secondary response is a memory response that occurs much swifter due to the primary response. The quantity of antibody is dependent on the infection and how long it lasts. There is no benefit to measure quantity. ...Read more

Can you explain the different kinds of midwives?

Complicated: There are many certifying bodies and also direct entry midwives. Midwives either enter specialty training to obtain skills nec for prenatal, labor, postpartum and newborn care after receiving rn (nursing degree) or via another professional non-rn program. Most are very highly skilled and work with back up from md when nec. http://mana.org/definitions.html http://www.Who.Int/features/factfiles/midw. ...Read more

Can you please describe the differences and similarities among a myelogram, mri, and ct?

Can you please describe the differences and similarities among a myelogram, mri, and ct?

See below: Mri is excellent looking at soft tissues such as brain, spinal cord, internal organs in chest and abdomen, and works via magnetic fluxes. Both cat and myelogram depend on radiation, the former provides screening of bones, sinuses, and the soft tissues above with far faster images, but less definition for smaller lesions. Myelogram images spinal canal by injection of dye, and is rarely used. ...Read more

Is there any test that docs can perform to tell the differences of what kinds of opiates you have in your system?

Is there any test that docs can perform to tell the differences of what kinds of opiates you have in your system?

Yes: Yes, although it can take a while. Most clinics and doctor's offices use an on-site urine or saliva screen for certain drugs and medications. What is gained in having quick results is occasionally lost with accuracy. Thus, sometimes the urine is sent out to a lab-- it is there that they can tell the difference between the different opiates among many others. The lab very rarely makes errors. ...Read more

Can you enumerate and differentiate the types of culture media?

Can you enumerate and differentiate the types of culture media?

Too many to address: I trust you mean media for bacterial cultures. There are general media for screening culture and even that varies with the source of the specimen and suspected organisms, There are sold media and liquid media. There are special media for many of the bugs. The variety is further magnified by aerobic and anaerobic types and so on. ...Read more

Are there any cardiologists that can tell me why the P wave on an ECG is pointed amplitude 2.5 mm and the U wave is tall? What are the possible causes of this if previous ECGS were normal

Are there any cardiologists that can tell me why the P wave on an ECG is pointed amplitude 2.5 mm and the U wave is tall? What are the possible causes of this if previous ECGS were normal

Standardization: a sudden increase in P amplitude and U amplitude when previous EKG was normal likely is due to change in the settings of the EKG machine with increased gain voltage amplitude which is indicated on the bottom left of the page should state 10 mm per millivolt. If this is not the case..... increased P amplitude indicates large atrium and increased U wave may indicate low potassium, or high Calcium ...Read more
