Resumen
When developing the degree work entitled remote monitoring system for high-risk patients with web visualization, using microcontrollers, it was necessary to make a study of existing projects, with the intention of ensuring the viability and reduce errors in the development of the device. The signals are captured through the AD8232 card which is a cardiac or ECG monitor. With the pulse sensor, the signal is displayed and the pulse rate is measured per minute. This is done by means of the IOIO OTG card which has a microcontroller that allows us to calculate and transmit via bluetooth. Thanks to the bluetooth connection is made the transmission which allows us the continuous sending of data, through a cellular application in the android operating system can display the ECG signal, pulse signal and pulsations per minute, once you have a signal with a certain amount of information is stored in the database which is connected to a web page. The web page contains clear information, with it the user can know in a few minutes everything about it. the aforementioned information is very reliable because it is necessary to guarantee the security of the data, which is why vulnerability studies were carried out on the page to avoid filtering information. All users who use this service may register as doctors or patients to enter the page to be monitored or to be monitored respectively. In addition to the signs displayed the doctor can see the patient's medical history, be in direct contact with this via e-mail. Also the patient will have the possibility to upload the information required by the doctor. The indicated characteristics will allow that this device can be monitored to patients of high risk, such as:1. Patients with a history of coronary artery disease; arrhythmias such as atrial fibrillation, implantable cardioverter defibrillators or cardiac pacemakers, and stage D heart failure. In these patients, an abrupt change in pulse or electrocardiographic tracing may force the patient to move, starting with maneuvers from home and preparing medical equipment hospital to provide all the tools that are needed in each case. 2. In this way, patients with congenital heart disease and cardiac tumors could be monitored closely by their cardiologist and thus plan the long-term follow-up. 3. Patients with syncope of unexplained cause could be monitored to evaluate the path at the time of their loss of consciousness and thus rule out cardiogenic origin. 4. Patients with terminal chronic renal failure in replacement therapy may also benefit from changes in the pathway, such as hyperkalemia. 5. Post-operative cardiac surgery patients may be monitored during the first year by their specialist from home to indicate if they require changes in medical management. 6. In an intensive care unit, the device could be used by the intensivists to perform telemedicine with sub-specialists and thus to evaluate as a whole whether a surgical procedure or other emerging medical therapy is required. 7. In addition to those already listed, there are other more interesting applications, they may derive from the use of the new device for use in patients with a history of high risk and requiring close medical care. It should be noted that during the development of the present study, laboratory tests were performed to test the effectiveness of the device.
