Résumé
Premature ventricular complex (PVC) is a frequent finding in the general population. The atrial conduction time (ACT) is the period between the electrocardiographic P wave and the atrial mechanical contraction, and its prolongation indicates an atrial electromechanical delay (EMD). In our study, we compared atrial conduction parameters by echocardiographic methods between patients with frequent PVC and healthy control subjects. The study included 54 patients with PVC and 54 healthy volunteers. Atrial conduction parameters were measured with echocardiographic examination. The time difference between the p wave and the Am wave was measured in the septal, lateral, and tricuspid annulus regions. The interatrial EMD, left atrial intra-atrial delay, and the right atrial intra-atrial delay were calculated from these measurements. The groups were compared for demographic and electrocardiographic features and echocardiographic parameters. Left intra-atrial EMD, right intra-atrial EMD, and interatrial EMD were significantly longer in the patient group ( Atrial conduction times are prolonged in patients with frequent PVC.

Background

Premature ventricular complex (PVC) is a frequent finding in the general population. The atrial conduction time (ACT) is the period between the electrocardiographic P wave and the atrial mechanical contraction, and its prolongation indicates an atrial electromechanical delay (EMD). In our study, we compared atrial conduction parameters by echocardiographic methods between patients with frequent PVC and healthy control subjects.
Methods
UNASSIGNED
The study included 54 patients with PVC and 54 healthy volunteers. Atrial conduction parameters were measured with echocardiographic examination. The time difference between the p wave and the Am wave was measured in the septal, lateral, and tricuspid annulus regions. The interatrial EMD, left atrial intra-atrial delay, and the right atrial intra-atrial delay were calculated from these measurements. The groups were compared for demographic and electrocardiographic features and echocardiographic parameters.
Results
UNASSIGNED
Left intra-atrial EMD, right intra-atrial EMD, and interatrial EMD were significantly longer in the patient group (
Conclusions
UNASSIGNED
Atrial conduction times are prolonged in patients with frequent PVC.
