Scientific Studies
Risk-based screening for the evaluation of atrial fibrillation in general practice (R-BEAT): a randomized cross-over trial
Summary: Among older community-dwelling adults with a CHA2DS2-VASc score of greater than two, screening with ELR for one week was associated with a 5.5% incremental detection of new atrial fibrillation over usual care.
Usefulness of Ambulatory 7-Day ECG Monitoring for the Detection of Atrial Fibrillation and Flutter After Acute Stroke and Transient Ischemic Attack
Summary: Following acute stroke or TIA, ELR identified patients with AF, which remained undetected with standard ECG and with Holter. ELR should, therefore, be considered in every patient in whom a cardioembolic mechanism is suspected.
How to measure arterial stiffness independently of blood pressure: the QKD method...
Summary: Ambulatory monitoring of QKD provides indices of arterial stiffness independent of blood pressure level and 24-hour blood pressure. This method has the potential to refine risk assessment in patients with low traditional risk scores.
Arterial stiffness (from monitoring of Qkd interval) predict the occurrence of cardiovascular events and total mortality
Summary: A study of 930 hypertensive patients over 12 years found arterial stiffness, measured by QKD interval, independently predicts cardiovascular events and all-cause deaths. This measurement is most predictive in low-risk patients.
Increased arterial stiffness is an independent predictor of atrial fibrillation in hypertensive patients
Summary: Arterial stiffness is a strong predictor of future atrial fibrillation in hypertensive patients, independently of age, 24-hour pulse pressure, and left atrial diameter. This finding was based on a cohort study of 853 patients with hypertension, with a mean follow-up of 102 months.
Determination of central blood pressure by a noninvasive method (brachial blood pressure and QKD interval): a noninvasive validation
Summary: A measure of central systolic blood pressure (cSBP) based on the QKD interval was validated against the SphygmoCor device. The QKD-based cSBP estimation algorithm, defined in a first cohort, showed good agreement with SphygmoCor in a second cohort and demonstrated comparable blood pressure variations during head-up tilt in a third cohort.
