Proper Placement Of Ecg Electrodes
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
Where on the scalp are electrodes placed in order to record a single channel of visual evoked potentials?
I think the question: You are asking is: Can you apply an external fixator under spinal anesthesia? That is a possibility to the lower extremity but it may be dependent on other factors such as other injuries elsewhere and the type of injury directly. An external fixation device also exists for the spine too. ...Read moreSee 1 more doctor answer
During routine echocardiogram, is the ejection fraction usually calculated using the m-mode estimate, or the 2d volume (tracing the lv) measurement?
Either: Both methods are used. However, it is generally accepted that tracing the endocardial borders of the left ventricle at end systole and end diastole in two separate planes gives the best estimate of ejection fraction. When using only the m-mode tracing, there are many assumptions built into the estimate of ejection fraction that can challenge accuracy. ...Read more
Is the removal of the wires used to close the sterum after heart bypass sugery a valid option in an effort to reduce non-cardiac chest pain?

Will the accuracy of mapping of the heart be compromised if general anesthesia is used during mapping for a pediatric atrial ablation?
Yes: Yes, absolutely. Avr usually has inverted t-waves normally. If you invert left and right arm electrodes, avr becomes avl so now avl has inverted t waves (where as typically it does not). ...Read more

What would abnormal septal motion on an echo and poor R wave progression on an ECG for the same patient suggest?
Spect images demonstrate inferior and apical reversibility from my nuclear stress test. Is a cardiac catherization must be done?
Not enough data...: Inferior ; apical reversibility means there is some ischemia in those regions. Without seeing the images it is difficult to tell how much. If there is very mild ischemia, some cardiologists may decide to do medical management (only medicines). If there is any significant amount of ischemia, cardiac catheterization is usually done. Again, it depends on the clinical scenario..Not enough data. ...Read moreSee 1 more doctor answer
What are the advantages of having a diagnostic cardiac catheterization through the groin arm or neck?
Groin/ arm/ neck: The difference lies mostly in operator preference and experience. There are higher complication rates when using the brachial (upper arm) approach due to ability to compress the artery after the catheter is removed. Some pain at the insertion site is possible after the procedure, which may be a consideration. ...Read moreSee 1 more doctor answer

I recently underwent a echocardiogram what does these results mean spectral doppler velocity of mitral valve inflow abnormal with reversal of the e and a wave amplitude ratio tissue doppler velocity of mitral valve annulus abnormal with reversal of the
Need more infomation: This is a method of looking at function during the part of the heart cycle know as diastole (when the ventricle relaxes). The information provided needs to be taken in context with other information such as pulmonary venous inflow to detemine whether there is diastolic dysfunction. ...Read moreSee 1 more doctor answer
