Article Synopsis
- A study was conducted to assess how atrial and ventricular pacing affects left atrial (LA) function after dual-chamber pacemaker implantation in 121 subjects with sinus node disease or atrioventricular block.
- Participants were grouped based on their pacing settings, with variations in atrial and ventricular pacing loads analyzed during follow-up visits at one and three months.
- Findings showed that high atrial pacing significantly decreased LA function, particularly affecting reservoir and contractile strains, whereas re-establishing atrioventricular synchrony in other groups maintained LA function levels.
: Chronic atrial stimulation might impair left atrial (LA) function. We aimed to assess the impact of atrial pacing burden on LA volumetric and functional parameters after implantation of a dual-chamber pacemaker. : The prospective study included 121 subjects with sinus node disease (SND) or atrioventricular block (AVB) that received a dual-chamber pacemaker.

We sought to determine the diagnostic value of speckle-tracking echocardiography derived myocardial deformation parameters at rest and during stress to determine hemodynamically significance coronary artery stenosis in patients with moderate and high probability of CAD.
Materials And Methods: In 81 patients (mean age, 64±8.
Early and late diastolic strain rate vs global longitudinal strain at rest and during dobutamine stress for the assessment of significant coronary artery stenosis in patients with a moderate and high probability of coronary artery disease.

Background: The aim of this prospective study was to assess the usefulness of global longitudinal strain (GLS), regional diastolic and systolic strain, strain rate (SR) parameters at rest and during dobutamine stress echocardiography for detecting significant coronary artery stenosis in patients with a moderate or high probability of coronary artery disease (CAD).
Methods: Dobutamine stress echocardiography and adenosine magnetic resonance imaging (AMRI) were performed on 127 patients with a moderate and high probability of CAD and left ventricle ejection fraction ≥55%. CAD was defined as ≥70% diameter stenosis on coronary angiography validated as hemodynamically significant by AMRI.
