    In this thesis paper we are presenting the result of analysis of Photoplethysmogram (PPG) signal of normal subjects and cardiovascular problematic subjects. Photoplethysmogram (PPG) is a non-invasive and inexpensive method for detection of cardiovascular disease. Photoplethysmogram is a technique that measures blood volume changes from skin which is close to arteries. PPG data were taken from 10 subjects and data were taken from subject’s index finger. Amongst 10 subjects 5 subjects were cardiovascular problematic patients and 5 were normal. Primary cardiac problem detection technique is Electrocardiogram (ECG). ECG is also a noninvasive technique but ECG is expensive compare to PPG. ECG machines are big, not portable and very expensive to have individually at home. ECG is more suitable for hospitals. ECG tests are also expensive. It will cost very large for anyone who wants to keep going on tests of cardiac disease detection at early stage. Compared to ECG PPG is very small, portable and inexpensive. All kind of people can afford PPG based system for cardiac detection at home. In this paper we presented two methods based on PPG signal to analyze cardiac disease one is pulse amped sensor and other one is smartphone. This paper presents all the research, techniques, and algorithm development to analyze cardiac disease using pulse amped sensor and smartphone both individually. Pulse sensor is affordable and 2.1 billion or more people already uses smartphone today's time so any system based on both or any of the way will be low cost and great for early detection of cardiac disease at home or anywhere. Pulse sensor and smartphone both can be a worth alternative of ECG. We hope this study will be valuable to create both or any of the monitoring system for cardiovascular disease detection.
