Postpartum Maternal Bradycardia Overview: Bradycardia in pregnancy:

Background: Hypotension or bradycardia after spinal anesthesia for cesarean section remain common and are serious complications. The current study evaluated factors associated to the incidences of hypotension or bradycardia in this context. Material and Method: A prospective cross sectional study from November 1, 2004 to July 31, 2005 was conducted on 722 parturients undergoing cesarean section...

Atrial Bradycardia

This paper describes a group of patients who have chronic bradycardia, due to a slow atrial rate. This can be the result of sinus bradycardia or produced by block between the sinus node and the atrium. The distinction between the two processes may be difficult, since electrical discharge of the sinus node does not give rise to a deflection on the standard electrocardiogram. For a start, therefo...

Reflex bradycardia during surgery.

Reflex bradycardia and sinus arrest may occur in a variety of surgical procedures, from neurosurgery to general abdominal, laparoscopic, ophthalmic and facial surgery and even procedures such as liver biopsies and electroconvulsive therapy. In most cases a vagally-mediated reflex has been implicated, although experimental support for this is often lacking. Drugs such as vecuronium, atracurium, ...

Fetal bradycardia in labor.

The prognostic significance of terminal bradycardia is analysed in this study. Amongst 12,145 intrapartal directly recorded cardiotocograms, 135 heart rate curves free of deceleration (1.1%) were found with an abruptly occurring fetal bradycardia. The mean duration of bradycardia was 5.7 +/- 3.1 minutes, the mean heart rate during the phase of bradycardia was 86.2 +/- 9.9 beats/minute. A premat...
