A good flat baseline is an essential feature in a NMR spectrum for several reasons. A flat baseline ensures integrity of integrals, reduces t1 noise in 2D spectrum and in indirect dimensions of nD spectrum. Baseline wobble in a nD dataset will lead to bad quality data.
What is the U wave in the ECG strip?
The ‘U’ wave is a wave on an electrocardiogram (ECG). It comes after the T wave of ventricular repolarization and may not always be observed as a result of its small size. ‘U’ waves are thought to represent repolarization of the Purkinje fibers. However, the exact source of the U wave remains unclear.
What is a deflection from the baseline?
By convention, the first upward deflection from the baseline is termed the P wave, and it reflects atrial depolarization. The P wave should not exceed 2.5 mm in height nor 0.11 second in width (i.e., less than three small boxes high and wide). Ventricular depolarization is represented by the QRS complex.
