WHAT THIS STUDY ADDS. The spatial twist of the vectorcardiographic loops of the QRS complex and of the T wave is measurable not only based on standard 12-lead ECGs but also based on restricted ...

The pattern of a short PR interval and a prolonged QRS complex was encountered at one time or other in 7 cases. Since the records represented 1356 patients, the incidence was 0.5 per cent.

Abstract: The purpose of this study was to describe the changes in high-frequency QRS (HF-QRS) components due to myocardial ischemia provoked by prolonged artery occlusion during percutaneous coronary ...

Eligible heart failure patients with a wide QRS complex spent more time alive after use of a cardiac resynchronization therapy defibrillator (CRT-D) compared with an implantable cardioverter ...

Did you know that certain medications can cause symptom of 'Electrocardiogram QRS complex prolonged'. Find these drugs listed on the page and be warned of similar symptoms as possible side-effects.

Objective To test the hypothesis that in recipients of primary prophylactic implantable cardioverter-defibrillators (ICDs), the non-planarity of ECG vector loops predicts (a) deaths despite ICD ...

Approach to the QTc measurement in the setting of prolonged QRS duration. The QTc captures both ventricular depolarization (the QRS complex) and ventricular repolarization (the ST segment and T-wave).

The QRS complex duration is prolonged (0.14 sec), and there is a right bundle branch morphology with an RSR' in V1 (→) and a terminal S wave in leads I and V5-V6 (←).

It’s well known that the benefits of CRT—established in patients with heart failure, reduced LVEF, and a prolonged QRS duration—are dependent on the characteristics of a patient’s QRS complex, ...

To further verify the relationship between Cx43 gap junction channels and the QRS complex, we perfused isolated hearts of normal rats with 18β-glycyrrhetinic acid (18β-GA) at different concentrations ...
