Pacemaker and conduction system myocytes play crucial roles in initiating and regulating
the contraction of the cardiac chambers. Genetic defects, acquired diseases, and aging …

The conduction system of the heart initiates and coordi-nates the electric signal that causes
the rhythmic and synchronized contractions of the atria and ventricles. In higher vertebrates …

Objectives: The purpose of this study was to perform a detailed analysis of the P-wave
morphology (PWM) in focal atrial tachycardia (AT) and construct and prospectively evaluate …

Objectives: We sought to investigate electrophysiological characteristics and catheter
ablation in patients with focal atrial tachycardia (AT) originating from the non-coronary aortic …

Objectives This study sought to report P-wave morphology (PWM) from a series of
paraseptal (PS) atrial tachycardia (AT), revise then prospectively evaluate a simplified PWM …

Objective: To characterize the electrocardiographic and electrophysiological features and
frequency of focal atrial tachycardia (AT) originating from the right atrial appendage (RAA) …

Atrial tachycardia (AT) may be focal or macroreentrant. In this review we will concentrate on
focal AT. The diagnosis of focal AT may be made from a standard electrocardiogram (ECG); …

Atrial tachycardia is an uncommon arrhythmia and may be focal or macroreentrant. This
review concentrates on focal atrial tachycardia. Over the last decade there have been a …
