WebFetal extrasystoles are the most common fetal arrhythmia that results in an irregular fetal heart rate (early or premature beat).; Benign and usually self-limiting and do not generally compromise cardiac function. Extrasystoles usually last < 750 msec.; Premature atrial contractions are more common than those of ventricular or junctional origin (however … WebAug 8, 2024 · Introduction. Premature atrial contractions (PACs) are contractions of the atria that are triggered by the atrial myocardium but have not originated from the sinoatrial node (SA node). PACs are also commonly referred to as atrial premature complexes (APCs), premature supraventricular complexes, premature supraventricular beat, and premature ...

WebOct 20, 2024 · The premature atrial contractions follow a usually normal ventricular contraction and are seen in doppler ultrasound as deep a waves, because they hit on a closed atrioventricular valve. If they are conducted, they are followed by a ventricular contraction which appears to be smaller than usual, because of the smaller stroke volume. redcliffe bus lines
