8.3 Provision of Health Care Information
The physiological indices of a person may show abnormality when his or
her health status is trapped in a bad state. Hence, it is necessary for the
user to obtain an
early warnin
g of this health status. HCloud can provide
further semiautomatic or automatic analysis of physiological data by means
of statistics and pattern recognition as well as data-mining methods. This
section introduces the online analyses of ECG with the Map-Reduce scheme
and presentation of the results via the cloud platform, as well as presenta-
tion of the other physiological signals (e.g., of the PPG and HBP), which can
provide convenient, customized health care service. An actual mobile health
system is described in Figure 8.7.
8.3.1 Online Analysis of ECG Data
The ECG is a transthoracic (across the thorax or chest) interpretation of the
electrical activity of the heart over a period of time, as detected by electrodes
attached to the outer surface of the skin and recorded by a device external
to the body
[18

. It is utilized to measure the rate and regularity of heart-
beats as well as the size and position of the chambers, which can diagnose
atrial premature beats (APBs), arrhythmia, myocardial ischemia, and so on.
Apart from simple records and general instructions, the system also pro-
vides detailed ECG physiological indexes for medical experts who need to
obtain complete user information for diagnosis. The most common forms
of arrhythmia, such as bigeminy, premature beats, bradycardia, and the
frequency of occurrence are autoanalyzed by related algorithms.
