It is a dollar in the sense that the value of the note is stated in units of one dollar. The statutory authority for the creation and issuance of Federal Reserve notes is provided by Â§ 16 of the Federal Reserve Act (see 12 O.S.C. S 411).
Related to QRS interval: QT interval. the duration of the QRS complex in the electrocardiogram. In the electrocardiogram, the interval that denotes depolarization of the ventricles, between the beginning of the Q wave and the end of the S wave. Its normal duration is 120â200 msec. Shorter durations are found, e.g., in preexcitation. Longer durations are indicative of first-degree heart block.
1 The normal QRS axis range (+90Â° to -30Â°); this implies that the QRS be mostly positive (upright) in leads II and I. 2  right of +60Â°. 3  Septal q waves should not be confused with the pathologic Q waves of myocardial infarction. 4  Precordial leads: (see Normal ECG).5  Small r-waves begin in V1 or V2 and progress in size to V5.T segment depression is always an abnormal finding, although often nonspecific (see ECG below). ST segment depression is often characterized as upsloping, horizontal, or downsloping. The normal U Wave: (the most neglected of the ECG waveforms). 1  U wave direction is the same as T wave direction in that lead.
