Arrhythmias can be classified by their origin (atria or ventricles) and by heart rate. Tachycardia. A fast (over 100 beats per minute) heart rate is called tachycardia.
What are products of the light and dark reactions of photosynthesis? The products of the light reaction are 602, 12 NADPH2 and 18 ATP.    The products of the dark reaction are C6H12O6, 12 NADP, 18 ADP, 18 Phosphates and 6H2O.
Carbon dioxide and water are the two reactants, and carbohydrates (glucose) and oxygen are the end products. Sunlight is the energy source for the endothermic reaction. Along with glucose, products including ATP and other intermediary chemicals are produced.arbon Dioxide, and water are the reactants. Glucose and oxygen are the products. Just remember there are other products that are made in the process of photosynthesis, but ar â¦ e used elsewhere. An example of this is NADPH. NADPH is a product of PS1, but then is used in the Calvin Cycle. 14 people found this useful.
