Novel Notch Detection Algorithm for Detection of Dicrotic Notch in PPG Signals
Photoplethysmography (PPG) is a non-invasive optical technique that measures relative blood volume changes in the blood vessels and is widely used for research and physiological studies. Dicrotic notch represent the closure of the aortic semi-lunar valve and subsequent receding blood flow when ventricles relax. Their location is used to calculate systolic time intervals and monitor cardiac func...
متن کاملOn an automatic delineator for arterial blood pressure waveforms
Arterial blood pressure waveforms contain rich pathophysiological information; hence receive much attention in cardiovascular health monitoring. To assist computerized analysis, an automatic delineator was proposed for the fiducial points of arterial blood pressure waveforms, namely their onsets, systolic peaks and dicrotic notches. The presented delineator characterizes arterial blood pressure...
متن کاملAn Open-source Algorithm to Detect Onset of Arterial Blood Pressure Pulses
In this paper; we present an effective algorithm for detecting the onset of anerial blood pressure (ABP) pulses. The algorithm employs a windowed and weighted slope sum function (SSF) to extract ABP wavefonn features. Aahptive thresholding and search strategies are applied to the SSF signal to detect ABP pulses and to determine their onsets. Two evaluation procedures were employed. First, pulse...
متن کاملThe dicrotic arterial pulse.
SUMMARY The study consisted of observations on nine male patients with palpable dicrotic carotid pulses. Average patient age was 37 years. All had advanced myocardial failure as evidenced by cardiomegaly and the presence of prominent atrial and ventricular diastolic gallop sounds. Most of these patients were diagnosed as having primary myocardial disease. The indirect carotid pulse was characte...
متن کاملSystolic peak foot-to-apex time interval, a novel oscillometric technique for systolic blood pressure measurement
BACKGROUND Noninvasive blood pressure (BP) measurement is essential for the study of human physiology but automatic oscillometric devices only estimate SBP and DBP using various, undisclosed algorithms, precluding standardization and interchangeability. We propose a novel approach by tracking, during pneumatic cuff deflation, the time interval from the foot to the apex of the systolic peak of t...
