Kang-Ping Lin Dept. of Electrical Engineering Chung-Yuan Christian University Handheld ECG A new step in Home care
Background on health management
High “medicare” cost and lower government coverage are the major trend now.
Ageing population in advanced economies show more occurrence of death threatening diseases such as cardiovascular diseases (CVDs).
Current health care system is complex, costly, inconvenient, passive (not active and not easy in implementing preventive medicine)
The need for a new model of high quality health care system that is simple, remote monitoring capability, self-manageable and affordable.
Current Status - Taiwan
Currently, government, research institutes and private organizations are supporting projects that are developing innovative
- Simple Home Use Medical Devices
- Remote Health Service System
- New Wellness Service Model
The above projects leverage on the advanced IT, electronic and medical management experiences in Taiwan
Creating a successful health & service model for implementation locally and internationally
Importance of Monitoring Heart Function Problems: Cardiovascular diseases (CVDs) is the second leading cause of death in the world, right behind cancer. There is no simple way to monitor heart function (ECG) easily except in hospital because traditional ECG require technicians to perform while Holters and event recorders are an inconvenience. They are only recording for a short term. It is difficult for users to monitor their ECG for a long term because there is no home use ECG tool available.
New device and tool to monitor ECG easily
Server System to collect data for long term wellness management
A more convenient medium for users and physicians to
manage health condition
Currently, blood pressure monitor, glucose meter, pulse oximeter are readily available by home users. However, the most important information of heart function lacked is electrocardiogram (ECG)
The purpose of this project is to
Develop a medical device for users to record their ECG data easily, anywhere, anytime
Implement a workable health service model in the monitoring of heart function
Market of this new ECG device and model to health care providers
Implement active preventive medicine focusing on heart function and CVDs
Purpose Create a new health and wellness management system - Focusing on Heart Function (Handheld ECG) Health Care provider Ageing Society

Telemonitoring and e-Health Service Health Prevention for high-tech workaholics
Responding to ITRI Health Management Plan:
Telemonitoring and e-Health Service EKG Health Care
Handheld ECG and its Applications Case A Case B
Handheld ECG and its Applications Case A Case B Normal subject Workaholic
Applications: Telemonitoring JMS, Japan : Many private health service providers only offers blood pressure, glucose meter, weight, etc as they are widely available in the market. Accurate, portable, easy to use personal ECG recorder is required to upgrade their current service system.
Handheld ECG and its Applications Applications : For Doctor For User Arrhythmia Control Drug evaluation Off-hospital monitoring Screening Health Management Health Prevention Prevention and Wellness Management
DEVICE: A handheld ECG device is developed successfully for that allows recording of ECG data by any user without the help of professional technicians
2. SYSTEM: A workable remote monitoring of heart function is achieved through the portable ECG device and IT management structure
3. BUSINESS: Many health care providers have now implemented ECG into their system. Their business scope has increased significantly due to the additional data. It allows physicians have the most critical data on heart and thus tighten the bond between physician-patient relationship.
4. PREVENTIVE MEDICINE: With the availability of handheld ECG to complete the monitoring system, health care providers and physicians can more effectively execute preventive medicine on heart problems.
