Read the labels. If the label lists sugar, sucrose, fructose, corn syrup, white or âwheatâ flour, they contain simple carbohydrates. If these ingredients are at the top of the list, they may contain mostly simple carbohydrates, and little else. They should be avoided.
A T-wave is a component of an ECG test. It signifies the repolarization of the heart ventricles after a contraction. In the adjacent image, the T-wave is the hump on the right. Every time your heart beats, the muscle is depolarized by an electrical current that originates in the sinoatrial node of the heart.
T wave. The T wave represents ventricular repolarization and is longer in duration than depolarization (i.e., conduction of the repolarization wave is slower than the wave of depolarization). Sometimes a small positive U wave may be seen following the T wave (not shown in figure at top of page).he different waves that comprise the ECG represent the sequence of depolarization and repolarization of the atria and ventricles. The ECG is recorded at a speed of 25 mm/sec, and the voltages are calibrated so that 1 mV = 10 mm in the vertical direction.
