The Smartphone Accessory Heart Rate Monitor
[attachment=68673]
INTRODUCTION
People don't use their Smartphone's for talking as much as they used to, but they are increasingly using them to detect and monitor their health.
Today’s telemonitoring devices are smaller and more user-friendly, and can monitor heart rate, blood pressure, oxymetry and weight.
Many Smartphone applications exist nowadays for measuring the user’s heart rate. One of which is through the Smartphone’s camera that can be used to detect changes in heart rate in a person’s finger using a technology called PhotoPlethysmoGraphic (PPG) measurement
ELECTROCARDIOGRAM(ECG)SIGNALS
Electrical waves cause the heart muscle to pump. These waves pass through the body and can be measured at electrodes (electrical contacts) attached to the skin. Electrodes on different sides of the heart measure the activity of different parts of the heart muscle.
An ECG displays the voltage between pairs of these electrodes, called Leads, and the muscle activity that they measure, from different directions
CONCLUSION
we described a design for a mobile accessory that once connected via USB to the patient’s Android based device displays his heart rate, calculated from his ECG extracted from two electrodes connected to his thumbs, and provides him with the option of sharing the result of his heart rate with his physician via SMS by a press of a single button. This proposed design is helpful for patients suffering from cardiac diseases as heart rate is an independent risk factor for patients with cardiovascular disease, in particular with arterial hypertension, myocardial infarction, coronary artery disease and heart failure. Studies demonstrated detrimental effects of increased heart rate on the function and structure of the cardiovascular system. Heart rate can be easily detected and therefore allows a conclusion on prognosis and efficiency of therapy.
