1 TRANSMISSION OF DIGITAL ELECTROCARDIOGRAM BY MODEM CONNECTION IN RURAL BRAZIL A L F Sparenberg, T Russomano, M A dos Santos, D F G de Azevedo Microgravity Laboratory/IPCT-PUCRS, Porto Alegre, RS, Brazil. Sociedade de Medicina de Sao Lourenco do Sul, RS, Brazil

2 Digital ECG System (D.E.S) Background The lack of cardiologists to analyze electrocardiograms (ECG) in small cities around the world, especially in developing countries, frequently delays the correct diagnosis of cardiovascular emergencies. Thus the delay in the provision of an analysis of an emergency ECG in Sao Lourenco do Sul (SLS) Brazil, a city with a population of 44,000, averaged 24 h before the introduction of a digital ECG system (DES) which allowed electronic data transmission to, and interpretation by, a remote cardiologist.

6 Hospital Santa Casa / Urban Hospital Walter Thophern Hospital /Rural Hospital Sao Lourenco do Sul, RS, Brazil # 2 Hospitals (1 Urban / 1 Rural) # 43 Physicians # 43 Physicians # 2 Cardiologists # 2 Cardiologists Mean time for ECG Analyses – 24 h, unsuitable for cardiovascular emergencies

7 D.E.S METHODS AND MATERIAL # Wincardio - Digital ECG Machine # Computers - 1 Desktop/modem/host/patient 1 Laptop/modem/cardiologist # Telecommunication Software - PC Anywhere/Symantec # Phone Lines - Fixed/Conventional Cell phone line (9.600 bits/s)

8 D.E.S METHODS AND MATERIAL # WINCARDIO - Digital ECG machine - 12 channel - Serial interface to PC/ bps - Response frequency: 0,05 – 128 Hz - A/D conversion 12 bits/sample 300 samples/s/channel - >100 MHz Pentium PC -1 PC (Desktop / Host) Pentium > 100 MHz Modem 56 K Windows 95, 98, 2000 or XP Serial Input -1 Laptop (Remote/Cardiol) Pentium > 100 MHz Modem 56 K Windows 95, 98, 2000 or XP Input for cell phone ???

9 D.E.S METHODS AND MATERIAL # TELECOMMUNICATION SOFTWARE PC Anywhere 32, 7.5 version – Symantec - HOST / Hospital - REMOTE / Cardiologist (Modem connection) # PHONE LINES -Remote Cardiologist Cell Phone Nokia model 6120i cable DLR-3P - Urban Hospital Fixed/Conventional Phone line - Rural Hospital Cell Phone Nokia model 7140i cable DLR-3P

10 D.E.S REQUIREMENTS # Time Effective: Early Diagnosis (on-line) # Cost Effective: Developing Country # Collaborative Technology: User of friendly systems # Enrolment of a Cardiologist

11 D.E.S ANSWERS TO REQUIREMENTS # Time effective – ECG transmission and analyses in approximately 10 min # Cost effective - Wincardio: U$ Computers: U$ PC anywhere: U$ 150 Cell / Fixed phones: U$ 200 TOTAL U$ # Collaborative Technology - Windows 95, 98, XP - Easy to teach and to learn ( User Friendly System.) - High Team motivation # Ensure the participation of local or regional Cardiologist..

12 D.E.S.RESULTS 1.A total of 1,100 digital ECGs have been made in the two hospitals since the implementation of D.E.S. 2.The time between data transmission and analyses with D.E.S. was around 10 min, which markedly decreased the previous estimated period of 24 h. 3.The utilization of a cell phone line has allowed the data transmission from a hospital located in a rural area where conventional phone lines are not available.

13 D.E.S.CONCLUSION 1. D.E.S. has proven to be of great benefit to patients with cardiovascular disease. 2. D.E.S provides a means of obtaining an immediate interpretation of an ECG by a cardiologist. 3.The low cost of this system makes it useful and appropriate for small cities and remote areas of developing countries where cardiologists are not available for on-site consultation. 4. It is believed that D.E.S can improve patients treatment with a consequent decrease in morbidity and mortality rates from cardiovascular diseases.
