Heart spectrum technology
a patented analysis technology of blood pressure measurement data, developed by OSTAR Meditech Corp. of Taiwan
detect identifiable heart noises, which are categorised as irregular heartbeats (cardiac arrhythmia), noises of heart valves and noises of corona arteries
display the analysis results with three numerical indexes, I1, I2 and I3, shows numbers from 0 to maximum 20 accordingly
The heart spectrum technolgy is a patented analysis technology developed by OSTAR Meditech Corp., Taiwan, by analyse the data collected on a blood pressure measurement to provide information about the healthy status of the heart. The results of the analysis are presented by three useful indexes that give an overview of the healthy status of your heart each time you measure your blood pressure.
Integrated with this patented technology, the OSTAR heart spectrum blood pressure monitor is a unique equipment for private use that shows much more information than just a roughtindication of an irregular heartbeat (heart arrhythmia).
Assessment of the clinical efficacy of the heart spectrum blood pressure monitor for diagnosis of atrial fibrillation: An unblinded clinical trial
Atrial fibrillation (AF) is the most common arrhythmia. The most common diagnostic method, 12-lead electrocardiogram (ECG), can record episodes of arrhythmia from which the type and severity can be determined. The Heart Spectrum Blood Pressure Monitor (P2; OSTAR Meditech Corp., New Taipei City, Taiwan) is used to measure cardiovascular pressure change with fast Fourier transform (FFT) analysis to obtain heart rate frequency variability and accurate blood pressure data. We compared the diagnostic efficacy of the Heart Spectrum Blood Pressure Monitor to a 12-lead ECG (gold standard) for patients with AF. Three measurement methods were used in this study to analyze the heart index and compare the results with simultaneous 12-lead ECG: blood pressure; mean arterial pressure, which was calculated from individual blood pressure as a constant pressure; and a constant pressure of 60 mmHg. The physician used a 12-lead ECG and the Heart Spectrum Blood Pressure Monitor simultaneously. The Heart Spectrum Blood Pressure Monitor used FFT analysis to diagnose AF, and the findings were compared to the 12-lead ECG readings. ......
simply measure your blood pressure
The heart spectrum technology is an analysis process of the data collected from the blood pressure measurement and then provides useful references for the health status of the heart.
The blood pressure measurement data was collected by the OSTAR heart spectrum blood pressure monitor, which uses the oscillometric method to measure blood pressure and pulse.
When the OSTAR heart spectrum blood pressure monitor making a blood pressure measurement, the sensor inside will detect the oscillations of the blood flow (the pulse) through the connected cuff on the user's upper arm and saves the data in form of a time-domain pressure wave.
When the measurement is completed, the analysis starts by converting the time domain pressure wave into a frequency domain wave using FFT (Fast Fourier Transformation) algorithm. The transformed frequency wave will display the primary frequency peaks showed in three frequency regions. If peak rates which are different from the primary peak rates are observed, these abnormal rate peaks are defined as heart noise and are quantified.
The quantitative calculation of heart noises is determined by the number of abnormal peaks in different frequency regions applying the proportional parameter determined from the results of a clinical pretest by removing the background noise.
Clinical trials find that the main frequency peaks of the tranformed normal blood pressure measurement data is displayed with three identifiable regions. Accordingly, the first frequency region is defined as the first heart rate frequency, and the second frequency region is defined as the second heart rate frequency, and the third frequency region is defined as the third heart rate frequency. The sum of heart noise in the first frequency region is the value of the heart spectrum index I1 , and the sum of heart noise in the second frequency region is the value of the heart spectrum index I2, and the sum of heart noise in the third frequency region is the value of the heart spectrum index I3.
Clinical trials also indicate that the heart spectrum index I1 is the noise index of arrhythmia, and the heart spectrum index I2 is the noise index of the heart valve, und the heart spectrum index I3 is the noise index of the coronary artery.
