An R point of a PQRST pattern in the filtered ECG data is determined (906). A portion of samples is selected from the filtered ECG data surrounding the R point (908). QRS duration of the PQRST pattern is then determined by processing the selected portion of samples using an application ...
Electrocardiography and mechanical remodeling is influenced by multiple factors such as cardiac structure, and cellular and molecular levels, which is manifested by prolonged QRS complex duration in the ECG. In the treatment of HF, in addition to traditional pacemakers, the emerged conduction system ...
Objective Longer QRS duration on the ECG is associated with increased cardiovascular (CV) mortality. To evaluate potential mechanisms, we examined in this study the relationship between QRS duration and left ventricular (LV) mass and LV end systolic and end diastolic volume in patients with known ...
AIMS. This study was conducted to determine whether prolonged QRS duration in electrocardiography (ECG) measurement could be used as a predictor for extended in-hospital length of stay (LOS) in congestive heart failure (CHF) patients. METHODS AND RESULTS. We obtained data of 147 patients who wer...

We aimed to evaluate if optimization by maximizing QRS duration (QRSd) reduction is feasible in an all-comer cardiac resynchronization therapy (CRT) popula
Data presented in this article relates to the research article entitled "Association between QRS duration on prehospital ECG and mortality in patients with suspected STEMI" (Hansen et al., in press) [1]. Data on the prognostic effect of automatically recoded QRS duration on prehospital ECG and ...

Relationship between QRS duration and left ventricular mass and volume in patients at high cardiovascular risk. Longer QRS duration on the ECG is associated with increased cardiovascular (CV) mortality. To evaluate potential mechanisms, we examined in this study the ... RA Stewart,AA Young,C Ander...
