TREATMENT OF SINUS BRADYCARDIA AND AV JUNCTIONAL RHYTHM WITH TRANSESOPHAGEAL ATRIAL PACING: HEMODYNAMIC EFFECTS OF PACINGTransesophageal atrial pacing (TAP) with the use of standard, thermistor-equipped, esophageal stethoscopes, modified for pacing by incorporation of a 4-French, bipolar TAP pr...
Sinus Bradycardia Sinus bradycardia is characterized by sinus rhythm with heart rates below normal for age (see Fig. 16.5). Slow heart rates can be observed during sleep or at times of high vagal tone. When there is significant sinus bradycardia, a slow junctional escape rhythm or a slow atri...
2). A 24-hour Holter monitor revealed sinus bradycardia with occasional junctional escape rhythm. The ventricular rate ranged from 59 to 135 beats/min (mean of 88 beats/min). The serum thyroid-stimulating hormone was 2.44 mIU/L (normal < 5), and free T4 was 6.8 pmol/L (normal 13-41)...

In 1960, Bacos et al 1 reported their investigation of a family with a "congenital familial nodal rhythm." They examined 2 brothers, 1 age 50 (IV-10, Figure 1), and the other age 42 (IV-14, Figure 1), with atrioventricular (AV) junctional bradycardia and intermittent atrial fibrillation...
They exhibit two SAs: the first one lasts for 7.2 seconds, followed by an atrioventricular junctional escape rhythm, and then a second arrest of 3.8 seconds. SA: sinus arrest. Figure 2 Open in figure viewerPowerPoint The holter monitor recorded a set of randomly occurring cardiac electrical ...
The normal cardiac rhythm that is typical is a normal sinus rhythm.Answer and Explanation: Bradycardia is a term that describes a slow heart rate. In the normal adult, one is considered bradycardic when the heart rates is observed at less......
Rhythm The cardiac rhythm can almost always be described in one of the following four categories: (1)sinus rhythm(or a sinus variant such assinus bradycardiaor sinus tachycardia); (2)sinus rhythmwith extra (ectopic) beats such asatrial premature beats(APBs) orventricular premature beats(VPBs);...
junctional escape rhythm (escape cycle > 1.5s) or atrioventricular block occasionally, with bundle branch block. Zhongshan Hospital of Shanghai Medical University according to the dynamic electrocardiogram (DCG) performance is divided into 4 types: type I, severe and persistent bradycardia (21.1%); ...
