Depolarization of the atria corresponds directly to the EKG's?
[non-professional opinion] Atrial repolarization is a much lower voltage event than atrial depolarization (the P wave) and it usually occurs during ventricular depolarization (the QRS complex). Therefore, it is too small to be clearly distinguished from noise on most EKGs and even if it were strong relative to the noise, would typically be obscured by the much stronger QRS complex.
A twelve lead electrocardiogram (EKG or ECG) shows a representation of the electrical activity of the heart as measured from 12 different perspectives (leads). The interpretation of EKGs allows a physician to determine if there are potential abnormalities or injury to the heart, at the time the EKG is taken.
A PCT in the medical field is intially called a Patient Care Technician, they are basically a certified nursing assistant but the difference is that they work in a hospital and they do phlebotomy and ekgs. They have more expereince than a CNA would have who workes in a nursing home who only does patient care.
When in the hospital, the person that performs Electorcardiograms (AKA: ECGs or EKGs) are usually done by EKG/ECG Technicianas, if there are none available an RN also knows how to perform them. If you're at a doctor's office, say, a Cardiologist, a Medical Assistant or nurse will perform the EKG/ECG.
Biological signal amplifiers are amplifiers designed to convert the weak voltage signal generated by various biological processes (nerve activity in EEGs, heart muscle activity in EKGs, etc.) into a strong signal. Almost every biological signal amplifier is built from an integrated circuit instrumentation amplifier.
This is directly from the Medicare and You 2009 book: Tests: Including X-rays, MRIs, CT scans, EKGs, and some other diagnostic tests. You pay 20% of the Medicare-approved amount, and the Part B deductible applies. See "Clinical Laboratory Services" on page 27 for other Part B-covered tests. If you get the test as a hospital outpatient, you pay a specified copayment that may be more than 20% of the Medicare-approved amount but can't be more…
Cardiovascular technologists and technicians assist physicians in diagnosing and treating cardiac (heart) and peripheral vascular (blood vessel) ailments. Cardiovascular technologists may specialize in three areas of practice: · Invasive cardiology · Cardiac sonography · Vascular technology/sonography Cardiovascular technicians who specialize in electrocardiograms (EKGs), stress testing and Holter monitors are known as cardiographic or EKG technicians.
The general field of Fourier analysis is often known as harmonic analysis. The Fourier analysis it occurs in the modeling time-dependent phenomena such as speech, EKGs, EEGs, earthquakes and tides. Examples also include the study of vibrations and circular, physical and rectangular pictures. It also involves the transmission of pictures including the weather or pictures of remote planets taken by space probes.
Why was it that when I was having a panic attack ekg computer reader said abnormal EKG but doctor said it was fine?
EKG readers provide only some very basic information about the patterns of EKGs. Some may make notes of alterations that don't actually represent disease, such as sinus bradycardia. Talk with your doctor for specific information about what your EKG reading said, and about why the doctor believed the notation was not a cause for concern.
The answer really depends on the state/province and country, as the laws are different everywhere. In some states chiropractic physicians are trained to perform and interpret EKGs, do venipuncture, perform urinalysis, even deliver babies and perform minor surgeries. Other staes have more narrow scopes of practice. To find out the laws in your state/province you should contact the chiropractic association or college in your area.

What are you asking? 1) EKG does not show any beer, ever. For that matter EKGs don't show drugs. They show your heart and how it's working. Drugs may affect that but many things do. 2) Blood & urine test for alcohol and drugs. 3) One beer one day ago will not show in any test. Our only current testing will show alcohol currently in your system, once it's out we can't test for it.
Thallium isn't only a chemical element in the periodic table, it's use in EKGs is very evident and important. It is a radioactive substance injected intravenously into a patient while being monitored exercising on a treadmill. The thallium mixes with the blood in the bloodstream and in the arteries enters the heart muscle cells. It shows how well blood flows to the heart muscle. It helps diagnose coronary artery blockage and heart function after a…
Chemistry is the foundation for anatomy and physiology and pathophysiology. It is important to understand these concepts. There are many aspects of nursing that require some knowledge of chemistry such as blood gasses, IV fluids, drugs, anesthesiology, etc. Also, electrolyte hommeostasis and action potentials (to understand heart physiology and read EKGs) make a lot more sense. Understanding chemistry allows the nurse to be able to think proactively. If the R.N. would want to go further…
