This paper presents a system to remotely monitor a patient's heartbeat and alert doctors or relatives if abnormal rates are detected. The system uses a heartbeat sensor to detect heart rate, an Arduino board to process the data, and a GSM modem to send SMS alerts to mobile phones if the heart rate is above normal. It aims to continuously monitor patients diagnosed with heart disease without needing direct supervision by automatically sending alerts for abnormal heart rate readings.

2. Cardio vascular diseases have shown that
heart beat rate plays a key role in the risk of
heart attack.
 Heart disease such as heart attack, coronary
heart disease, congestive heart failure, and
congenital heart disease is the leading cause
of death
 This paper presented a system that being
developed which able to monitor and alert the
patient’s relatives or doctors about the
patient’s heartbeat conditions

3. BLOCK DIAGRAM

4. • Heartbeat is sensed by using HRM2511E, heartbeat
sensor
• It uses the principle of PPG (Photoplethysmograph).
• The change in volume caused by the pressure pulse is
detected by illuminating the fingertip’s skin with the light
from an LED using a photodiode sensor.
• With each heart beat, a surge of blood is forced through
the vascular system, expanding the capillaries in the
finger, and changing the amount of light returning to the
photo detector

5. 2.ARDUINO UNO
•The Uno is a microcontroller
board based on the ATmega328P.
•The Uno can be programmed
with the Arduino Software (IDE).
•Here the Arduino is programmed
to monitoring the heart beat
•It is interconnect the sensor
module with GSM modem

6. 3. GSM MODEM
• A GSM modem can be an external device or a PC
Card / PCMCIA Card.
• Typically, an external GSM modem is connected to
a computer through a serial cable or USB cable.
• Like a GSM mobile phone, a GSM modem requires
a SIM card from a wireless carrier in order to
operate.
• GSM modems support a common set of standard
AT commands. With the AT Command, reading and
sending message can be done without any doubt.

7. 4.MOBILE PHONE
•When the heartbeat goes above normal
rate, the doctor or the patient’s relatives
gets an alert message in their mobile
phone.
•The number of SMS messages
that can be processed by a GSM modem
per minute is very low which only
about six to ten SMS messages per minute.

8. WORKING
• For a patient whom already diagnosed with fatal
heart disease, their heart rate condition has to be
monitored continuously.
• Heartbeat is sensed by using a heart beat sensor.
•Signal is processed using Arduino UNO to determine
the heart beat rate per minute.
•When the heartbeat signal is detected as high,
the input is processed and analyzed.
•The interfacing betweenArduino to GSM modem is
established by using HyperTerminal.
•Then, it sends SMS alert to the mobile phone of
Medical experts or patient’s family members, or their
relatives via SMS.

9. APPLICATIONS
•EEG, ECG and other health parameters
can also be monitored.
•Continuous monitoring and future
diagnosis can be performed via the same
system (TELEMEDICINE).
•More than a single patient at different
places can be monitored

10. LIMITATIONS
•Heart beat per minute is not highly
accurate as in real case.
•More than a person can’t utilize the
same system at the same time.

11. CONCLUSION
•Biomedical engineering (BME) is the
application of engineering principles and techniques
to the medical field. It combines A medical device
is intended for use in the diagnosis of disease, or
in the cure, treatment, or prevention of diseases.
•Thus in Implementation of Wireless Systems
for Patient Monitoring System, the heart beat and
body are successfully sensed This project will
eventually reduce man power in the very near future
