Improved ECG triggering with the T-wave Terminator

چکیده
INTRODUCTION. MR imaging of the heart and thoracic vessels requires ECG gating to compensate for cardiac motion. Triggering is accomplished by synchronizing the image acquisition pulse sequence to the R-wave of the ECG. However, the magnetic fields within the bore of the scanner can cause artifacts in the ECG waveform which result in gating errors. In addition, small variations in electrode position on the thorax can result in an unusable ECG signal.

Acoustic cardiac triggering: a practical solution for synchronization and gating of cardiovascular magnetic resonance at 7 Tesla
BACKGROUND To demonstrate the applicability of acoustic cardiac triggering (ACT) for imaging of the heart at ultrahigh magnetic fields (7.0 T) by comparing phonocardiogram, conventional vector electrocardiogram (ECG) and traditional pulse oximetry (POX) triggered 2D CINE acquisitions together with (i) a qualitative image quality analysis, (ii) an assessment of the left ventricular function para...

Background: To compare image quality and radiation doses of low kilovolt (kV) “prospective ECG-triggering” (PT) and standard “retrospective ECG-gating” (RG) coronary computed tomography (CT) angiography. Materials and Methods: A total of 101 consecutive patients (76 males, 25 females; mean age: 55.44 ± 8.28 years) with low-to-intermediate risk status for coronary artery disease and with a body ...

The theoretical and experimental rational of atrial signal-averaged ECG in patients with AF is delay in the intra-atrial and interatrial conduction. Similar to the ventricular signal-averaged ECG, the atrial signal-averaged ECG is an averaging of a high number of consecutive P waves that match the template created earlier P wave triggering is preferred over QRS triggering because of more accura...

Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...
متن کاملT-wave inversion in the aVL lead is associated with severity of stenosis in the LAD artery
Background & Aims: The clinical value of T wave inversion (TWI) in the lead aVL in diagnosing coronary artery disease (CAD) remains unclear. Hence, we aim to evaluate the association between TWI in the aVL lead and the severity and location of coronary artery stenosis in elective coronary angiography. Material and Method: Electrocardiograms (ECGs) of 167 consecutive patients undergoing electiv...
