Heart Rate Variability (HRV) is an important tool for the analysis of a patient’s physiological conditions, as well a method aiding the diagnosis of cardiopathies. Photoplethysmography (PPG) is an optical technique applied in the monitoring of the HRV and its adoption has been growing significantly, compared to the most commonly used method in medicine, Electrocardiography (ECG). In this survey, definitions of these technique are presented, the different types of sensors used are explained, and the methods for the study and analysis of the PPG signal (linear and nonlinear methods) are described. Moreover, the progress, and the clinical and practical applicability of the PPG technique in the diagnosis of cardiovascular diseases are evaluated. In addition, the latest technologies utilized in the development of new tools for medical diagnosis are presented, such as Internet of Things, Internet of Health Things, genetic algorithms, artificial intelligence and biosensors which result in personalized advances in e-health and health care. After the study of these technologies, it can be noted that PPG associated with them is an important tool for the diagnosis of some diseases, due to its simplicity, its cost–benefit ratio, the easiness of signals acquisition, and especially because it is a non-invasive technique.

Internet of Things (IOT) is the technology that can help integrate both physical and digital worlds. With associated technologies like Wireless Sensor Networks (WSN), communication standards and Radio Frequency Identification (RFID), to mention few, it has got plenty of use cases in the real world. One such use case is healthcare industry. Since healthcare industry needs seamless integration and quality in health care services, IoT has become crucial for taking the industry to the next level in providing satisfactory services. There are many benefits of integrating IoT with the infrastructure of healthcare units. One important benefit is real time health monitoring. With wearable technology patients can have body sensors and doctor can view vital signs of patients live. This could help in providing real time healthcare services so as to provide timely diagnosis and treatments. It also avoids many conventional barriers like travelling and wasting time. Still it is in its inception therefore, this paper throws light on the present state-of-theart of IoT and its integration with healthcare units. It provides useful insights on various aspects of integration besides giving recommendations.

“…The original model assumed the placement of a light source and a detector on two sides of the tissue being examined. In this way light, which was passed through absorbent substances, was detected and quantified [10]. The disadvantage of this model was the application limited to superficial tissues, transmitting the right amount of light.…”

The development of medicine and the ability to conduct effective therapy in increasingly severe cases create the need to develop new methods of continuous and non-invasive monitoring of the patient's condition. One of the techniques that is widely used in many fields of medicine is photoplethysmography (PPG). The analysis of the latest research indicates that PPG can have much more applications than the measurement of heart rate and arterial saturation of the patient-as shown by the latest research, it can be used in the measurement of many other key parameters. The optimism is the multitude of areas in which PPG monitoring is attempted. There are more and more attempts to use photoplethysmography in diagnosis and evaluation of peripheral vascular diseases, assessment of circulation in diabetic patients and assessment of endothelial function. Authors are focusing on new applications of PPG, its advantages and limitations. Most of them agree that PPG can provide useful knowledge about the patient's condition while being a quick, easy-to-use and cost-effective technique. The following review was created to critically analyze the latest technical developments and uses of PPG in clinical practice. Sources for the following article were found using the PubMed database using keywords such as "photoplethysmography", "oxygen saturation" and "pulse oximeter".
