Despite these extensions, the quality standards remain high because these applications are highly health related. Currently, vital signs monitoring involves measuring a series of physiological parameters that indicate the health of an individual. Heart rate is one of the most common parameters and can be detected by an electrocardiogram, which measures the frequency of the heart beats and, most importantly, the variation of the heart beats. Heart rate variability is often caused by activity. During sleep or rest, the rhythm is slow, but tends to increase with physical activity, emotional response, stress or anxiety. Heart rate outside the normal range may indicate the presence of a disease such as bradycardia (when the heart rate is too low) or tachycardia (when the heart rate is too high).
