What Do The Letters Qrs Mean On The The Electrocardiogram
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
Several ways to view: There are many ways to view the psa. Age based, most assays have 2.5 as the high for a 45 year old and higher values as you age. Psa velocity is probably the best way to view, it's how fast it's rising. You want it <0.7/year. Psa density, free vs total are other ways. ...Read moreSee 1 more doctor answer
Can someone, please, explain in the commonest words what does ECG axis mean? How do you see it is abnormal/normal on the ECG?
Axis deviation: EKGs show cardiac rate, rhythm, and axis. Axis deviation is determined by whether the QRS complex is positive or negative in leads I and AVF. If the axis is positive in both leads I and AVF, called "both thumbs up" the axis is normal. Axis interpretation can generally be described as trying to determine where the heart has an electric conduction defect, fascicular blocks, and axis deviation. ...Read more
A few include...: Reports are not always standardized so there is local variation. In general, a few of the abbreviations used for the type of ultrasound you describe are: us or u/s: ultrasound ruq: right upper quadrant (of abdomen) cbd: common bile duct gb: gall bladder abd: abdomen wnl: within normal limits cd or cdi: color doppler or color doppler images i hope that helps... ...Read more
Usually direction : Usually direction of blood flow, the colors are changeable and are set usually to indicate the direction of blood flow towards or away from the probe, typically red means towards and blue away from. Mixture of colors or color aliasing occurs where there is turbulent flow. ...Read moreSee 1 more doctor answer
Posterior wall?: You probably meant to say posterior wall, instead of posterior valve. But it probably means there is a blockage in the coronary artery that is feeding the posterior wall of your heart. This can be confirmed with a coronary angiogram and potentially fixed with coronary angioplasty and stent placement or else coronary bypass surgery. ...Read moreSee 1 more doctor answer
Helpspreemiesbreathe: Premature infants often do not have enough surfactant at birth. This surfactant is made by everyone to help keep the alveoli open to facilitate gas exchange. Sometimes a surfactant needs to be administered by endotracheal tube to the lungs to help tide the infant over until the infant makes enough-1-2 days. There is surfactant derived from cow and pigs lung. There is also a synthetic surfactant. ...Read more
In SIMPLEST terms... can you explain ECG axis... what axis (left/right) deviation means...and how to spot it on ECG. thanks?
Electrical axis: Roughly corresponds to size & shape of heart. No simple answer. Can indicate left or right ventricular muscle enlargement, left or right atrial enlargement, dextrocardia, loss of activity by a portion of heart muscle. After you get your MD you can spend some time learning to interpret cardiograms. It is hard. Most Drs are not good at it. ...Read moreSee 1 more doctor answer
EMG report say the sensory nerve conduction amplitude in the Right lower limb were on the lower limits of normal. What does that mean?
Means it's normal: Low or high end of normal is still normal when it comes to that sort of statement on an EMG report. If, however, the clinical situation were explained a bit more or if there were other EMG's you've had in the past that show a distinct change from these results then, there might reason to question the stated "normality." Otherwise, be glad you're done with the test! Good luck. ...Read more
My emg said i damaged the sensory part of the radial nerve in the forearm! what does the numbers mean on the test? 26 it should be 50 or higher! :(
My ECG report says 'sinus rhythm r-s transition zone in v leads displaced to the right. what does that mean exactly ?
Nothing: It is a description of the ectrical orientation of the hearts excitation and by in itself means nothing . ...Read more
Distance: The lengthier arms means absolutely nothing except the distance from your shoulder to your fingertips. There is a tremendous genetic variation on arm length. ...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
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 moreSee 1 more doctor answer
