Wireless heartattack detector

  1. 1. BY MANOJ. CT NIKHYDA.N
  2. 2. Heart attack (coronary artery disease) Coronary artery disease is one of the most common and serious effects of aging. Fatty deposits, plaque (cholesterols), emotional stress, drugs intake builds up spasm in blood vessel walls and narrow the passageway for the movement of blood. The resulting condition, called atherosclerosis often leads to eventual blockage of the coronary arteries and it is referred as “ heart attack”.
  3. 3. signs and symptoms Signs & Symptoms indigestion & Heartburn Lose of sensation Shortness Of Breath Discomfort in Left arm,jaw, Back & neck Chest pain For a normal human the symptoms will start before 1 week, critical symptoms are shown before 20 min. The other symptoms are: Anxiety, repeated cough with mild pain in chest, shortness of breath, sweating even in normal condition. For the elderly people (i.e., people with diabetes) they may have unusual symptoms (shortness of breath, fatigue, weakness). This may leads to "silent heart attack" which is a Heart attack with no symptoms.
  4. 4. Present detection and treatment available [For the serious cases] Electrocardiogram (ECG or EKG): The ECG can detect abnormal heartbeats, some areas of damage, inadequate blood flow, and heart enlargement. Treadmill Stress During exercise, healthy coronary arteries dilate (develop a more open channel) than an artery that has a blockage. This unequal dilation causes more blood to heart muscle supplied by the normal artery. In contrast, narrowed arteries end up supplying reduced flow to it's area of distribution. This reduced flow causes the involved muscle to "starve" during exercise. Nuclear scan This test shows areas of the heart that lack blood flow and are damaged. It also can reveal problems with the heart’s pumping action. Coronary Balloon Angioplasty . The tests used to make the diagnosis of coronary artery disease and its medical treatment Many patients with serious disease or those who fail on medical therapy are treated with a "needle hole" or "percutaneous" (through the skin) procedure called Angioplasty..
  5. 5. Present detection and treatment available [For the normal cases] Heart Basics 101 provides the viewer with fundamental information about the structure and function of the heart. Physical Examination: During this phase of the cardiac evaluation, the patient is examined by the physician. TEE or TE Echo cardiogram: TEE uses ultrasound to examine the heart with the use of a probe that looks at the heart from the back. Isotope stress test :An isotope tracer is used to increase the accuracy of a stress test in helping diagnose coronary artery disease. Holter monitor: This is a 24 hour tape recording of the patient's EKG. It is used to diagnose the cause of symptoms such as black outs, dizziness, irregular heart beats and coronary artery spasm. Heart attack or acute MI: This section provides fundamental details about a heart attack together with its cause, symptoms and treatment. Angiogram: A thin and flexible tube or catheter is inserted into the blood vessel of the arm or leg and guided to the heart with the use of x-ray. Contrast or "dye" is injected to help diagnose heart disease.
  6. 6. The disadvantage of the present detection devices oIt cannot be used by the normal people except the experts who have learnt to handle it. oLack of awareness. oAnd these detecting devices are very costly and cannot be Owned by individuals. oMore over if only the patient under observation the device can detect and hence it is not possible for all the cases.
  7. 7. To over come the disadvantage of present detection devices ,we have implemented heart attack detector in a digital wrist watch. Our device will detect the heart attack when the symptoms which starts in the body, this information will spread to other members and hospitals simultaneously self awareness of the patient is possible when this watch is wore by the respective person. Wireless heart attack detector in wrist watch The goal is to provide early heart attack detection so that the patient will be given medical attention within the first few critical hours, thus greatly improving his or her chances of survival. But our innovation is to support both heart patients as well as the normal persons.

TEMPERA P ULSE -TURE SENSOR SENSOR TISSUE PRESSURE SENSOR SENSOR TEMPERA P ULSE -TURE SENSOR SENSOR TISSUE PRESSURE SENSOR SENSOR PIC MICRO CONTROLLER PIC MICRO CONTROLLER BUZZERBUZZER LEDLED Transmission to 10 numbers programmed in it Message transmitted to the list of contacts described. Block Diagram of the construction in Wrist watch GSM & GPS
  9. 9. The operation of the heart attack will be performed on the basis of the results sensed by the sensors plates installed on back of the wrist watch. As per the block diagram,  The tissue sensor will identify the blood flow through in the blood vessel in our hand. If there a lack of blood flow, it will identify and produces a negative result  The temperature sensor work according with pressure sensor to send the signal The pulse sensor in the device will sense the pulse rate of the heart and checks it with abnormal pulses programmed if it matches then it will produces a negative result. Operation of the sensors
  10. 10. Pulse sensor is also programmed to identify the state of angina. The Heart Rate sensor measures heart rate between 0 and 200 bpm (beats per minute). The pressure sensor will identify the condition, which is programmed as: Exceeding the stage 2 hyper tension will lead to heart attack If the results are negative then all the sensors output will be logic 1 or else logic 0. Low blood pressure level CATEGORIES SYSTOLIC DIASTOLIC Normal < 120 and <80 Prehypertension 120-139 or 80-89 Stage 1 hypertension 140-159 or 90-99 Stage 2 hypertension > 160 or > 100 High blood Pressure level
  11. 11. Buzzer Flow chart of the operation in the wrist watch If (Sensor condition = normal) If (Sensor condition = normal) Manipulation of Sensor results Manipulation of Sensor results Gsm and tracking program enabled red led for abnormal /blue led for angina red led for abnormal /blue led for angina yes no
  12. 12. These signals are feed to Pic micro controller, which in turn gives the output according to the results. In pic micro controller ,logic AND performance is done with the 4 inputs from the sensors. According to the output of the pic micro controller, i.e. if the condition is abnormal then it glows red led and ON the buzzer for self awareness of the person who is wearing it which would help for self rescue. Then it activates the GSM and message will be sent to the 10 contact numbers of known members which will be stored in it. Using tracker system the location of the patient is also transmitted along with the alert message transmitted.
  13. 13. ADVANTAGES: PORTABLE LOW POWER COMSUPTION. AWARENESS TO THE PATIENT TO TAKE PRECAUTIONS. LESS COST WHEN COMPARED WITH THE OTHER EQUIPMENTS USED FOR HEART ATTACK DETECTION. DECREASES DEATH RATE DUE TO HEART ATTACK. EVEN HUGE HEART DAMAGES CAN BE PREVENTED CAN BE USED DAILY AND EFFICIENTLY WITH THE AVAILED RECHARGEABLE EQUIPMENTS WITH IT.
