However, the aortic dimension changes during the cardiac cycle due to cardiac pulsatility and aortic wall compliance. Thus, the electrocardiogram (ECG)-gated CTA that could obtain images at different ...

Electrocardiogram (ECG) monitoring is non-invasive, well tolerated by patients and provides continuous electrical information about the heart. It is frequently used in critical care areas such as the ...

Figure 3C shows an example of the ECG cardiac cycles aligned and the corresponding coherent mean cardiac cycle. The correlation analysis for the ACC signals is slightly more complex because the exact ...

A cardiac cycle consists of two phases: systole and diastole. During systole, the heart muscles contract, and during diastole, they relax.

Vivalink, a leading provider of digital healthcare solutions, announces its wearable ECG monitor is supporting research at Brigham and Women's Hospital in Boston aimed at understanding and ...

D, Retrospectively ECG-gated image at same level using reconstruction window of 215 ms centered at 50% of cardiac cycle. Decreased motion artifacts permit clear visualization of right coronary artery ...

Background The primary objective of pre-participation screening in athletes is the detection of potentially lethal cardiac conditions. The American Heart Association (AHA) recommends a directed ...
