t wave inversion造句

• In the case of digitalis administration, ST depression or T wave inversion may occur without indicating toxicity; however, PR interval prolongation indicate toxicity.
• At this point there may be signs of " ventricular strain pattern " ( ST segment depression and T wave inversion ) on the EKG, suggesting subendocardial ischemia.
• The ECG findings most commonly seen in myocarditis are diffuse T wave inversions; saddle-shaped ST-segment elevations may be present ( these are also seen in pericarditis ).
• In the ECG above, you can see an example of the rSR'pattern in V1 with a R'greater than S with T wave inversion which is commonly seen in volume overload Right Ventricular Hypertrophy.
• Other EKG signs include a right bundle branch block as well as T wave inversions in the anterior leads, which are " thought to be the consequence of an ischemic phenomenon due to low cardiac output in the context of RV dilation and strain ."
• Unstable angina ( UA ) and non-ST elevation ( non-Q wave ) myocardial infarction ( NSTEMI ) differ primarily in whether the ischemia is severe enough to cause sufficient damage to the heart's ECG changes indicative of ischemia ( e . g ., ST segment depression or transient elevation or new T wave inversion ).
