heart rate monitor

In a hospital, especially in the Intensive care unit (ICU), where seriously ill patients are treated, monitoring of the patients heart rate, blood pressure, temperature, oxygen level in blood etc. is very important. Electronic biomedical equipments continuously mo..

The number of times the heart beats per minute is called heart rate. For a normal adult human it is about 72 times per minute. For infants, it is a higher figure. It also goes up during physical exercise. The contractions and relaxations that the heart chamb..

The rhythmic contraction and relaxation of the heart to pump out and receive blood is called the heart beat. The rate of the heart beat varies from species to species. The smaller the animal, the higher is the metabolic rate and so greater is its ..

The Heart Beat - The heart beat results in electropotential differences spreading over the heart muscles. These follow a specific pattern. Any change in the pattern indicates an abnormality. The pattern can be recorded using an electrocardiograph. The recorded pattern ..

The cardiac muscles of the heart have the property of excitability and conductivity. When these muscles are stimulated, they get excited and initiate waves of electric potential called cardiac impulses, which are conducted along the special cardiac muscle fibres on the wall of the he..

The heart has an increasing rhythmic activity. It pumps blood by its contraction and relaxation. The contraction of the heart is called systole and the relaxation is called diastole . The contraction and relaxation together constitute the heart beat. The heart..

The control of the heart function is by a set of muscles and is, therefore, called myogenic . If the heart is removed from a living mammal and placed in a well oxygenated salt solution maintained at 37 o C, the heart continues to function though at a slower rate..

Rate of a Reaction - Rate of reaction basically means the speed at which a chemical reaction occurs. The speed of a reaction is determined by monitoring the concentrations of the reactants or products at intervals of time. The volume of the reaction vessel is kept cons..

The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or volume (as in the case of gas phase reactions), pH, optical rotation, el..
