The clinical significance of premature atrial contractions: How frequent should they become predictive of new-onset atrial fibrillation Ann Noninvasive Electrocardiol . 2020 May;25(3):e12718. doi: 10.1111/anec.12718. Se hela listan på obgproject.com Aims: Frequent premature atrial contractions (PACs) are associated with increased risk of atrial fibrillation (AF), stroke, and death. This study aimed to explore the electrophysiological features of PACs with and without inducing AF and to evaluate the effectiveness of catheter ablation for PACs. Premature atrial contractions (PACs) is a medical condition in which the heart beats too early due to premature discharge of an electrical signal in the atria, which are the two upper chambers of the heart. PACs is one of the most common types of arrhythmia, a general term to describe a heartbeat that is too fast, too slow, or irregular (uneven).

Premature atrial contractions (PACs) are premature heartbeats that are similar to PVCs, but occur in the upper chambers of the heart, an area known as the atria. PACs do not typically cause damage to the heart and can occur in healthy individuals with no known heart disease. "Premature atrial contraction An early heartbeat that originates in the heart’s upper chambers (atria) is a premature atrial contraction (PAC).

A PAC results in an electrical impulse coming earlier than expected, and in most cases causes an extra contraction of the heart. Premature Atrial Contractions (PACs) are one type of premature heart beat, irregular heart beat or benign arrhythmia.

Premature atrial contractions (PACs) are extra atrial beats that appear occasionally between normal SA nodal beats. They can consist of only an occasional extra beat or many such extra beats. PACs are normally not very troublesome to the patient, but they can indicate the presence of some degree of atrial pathology, and be a harbinger of the more serious atrial tachycardia or atrial fibrillation.
