Ambulatory Biopotential Measurement, Lakshmi Chitra Penugonda

Theses

Biopotential signals measure the electrical activity of different parts of the body. Conventional bedside monitors only provide information about the body under restricted conditions. Observation and documentation of biopotential signal during daily activities and the relation to patient symptoms may be important factors for clinical decision-making. Ambulatory monitoring helps to monitor the biopotential signal of a patient in the natural environment. The effective ambulatory system can help a physician to diagnose the patient's abnormality.

In this project, a low cost and flexible ambulatory biopotential system, compared to the commercially available systems, was designed and tested. Concurrently a software program was …

Ambulatory Measurement Of Body Position, Swetha Vennamaneni

Theses

Ambulatory monitoring is playing an important role in the clinical and research field. In the modem era, physicians are showing much interest in measuring heart rate, blood pressure and many other physical and cardiac conditions and recording electrocardiogram (ECG, a popular technique for diagnosing heart related disease), while the patient is ambulatory. Heart rate, blood pressure and ECG waveform can change because of body position. In the case of the ECG, the changes caused by body position are can change the ST-T segment and also the QRS amplitude. The heart rate and blood pressure changes when there is a change …
