In this patient population, the higher percentage changes in ES-GLS are mainly due to the lower absolute values of ES-GLS. The lack of available data makes it very difficult to determine the clinical relevance of a certain measurement error in regional strain measurements. We assume, however, ...
What would happen to the ECG trace if the subject sneezed or laughed during a recording? Why? Describe the characteristic of the lymph nodes associated with chronic inflammation. Include patient examples with intervention needed. Determine whether the following is a clinic...
The limb leads record the ECG in the coronal plane, and so can be used to determine the electrical axis (which is usually measured only in the coronal plane). The limb leads are called leads I, II, III, AVR, AVL and AVF. Figure 2 shows the relat...
Traditionally, peripheral blood oxygen saturation (SpO2) is a measurement taken at the peripherals of the body on the finger or ear, most commonly with a clip device to determine the ratio of oxygen saturated hemoglobin to total hemoglobin. This measurement is used to tell how well red blood c...
There are several diagnostic algorithms to determine the site of origin using the 12 lead ECG [29, 30]. QT prolongation and torsades de pointes (Tdp) polymorphic VT The patients who are admitted to the ICU/CCU usually have several risk factors that can predispose them to QT prolongation and...
Answer to: How does the ECG vary and what is occurring during these conditions: junctional rhythm, second degree heart block and ventricular...
In the case of severe epicardial spasm, it may not be possible to determine whether microvascular spasm coexists. Reflecting the role of the right coronary artery to supply the sinus and atrioventricular nodes (or circumflex in left-dominant anatomy), transient bradycardia commonly occurs. Given ...

Reducing false positives is preferable to current strict STAN guidelines. Present ST-analysis compares absolute T/QRS ratio rises to its baseline. As fetal heart axis orientation varies, fetal vector ECG parameters vary, resulting in interpatient T/QRS baseline differences. We hypothesize that ...
What are the two factors that determine cardiac output? How are these factors regulated? Explain why the atria have thinner walls than the ventricles of the heart. How do the cardiovascular, respiratory, and nervous systems contribute to muscle contraction? How would the heart rate be affected ...
