pathological Q-waves, left axis deviation and conduction delays and findings suggestive or diagnostic of primary electrical diseases such as long QT syndrome and Wolff-Parkinson-White syndrome. The ...
Fourteen studies and two case series were found describing ST-segment abnormalities and/or significant Q-waves in association with cocaine use. Not surprisingly, this literature overlaps ...
The most common ECG finding of an acute pulmonary embolism is sinus tachycardia; however, the classic finding is an S wave in lead I, Q wave in lead ... Type I is deep inverted T waves in the ...
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves ...
These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...
