Unusual sinus arrhythmia

International Journal of Cardiology, 2008
A juxtaposition of long and short RR intervals was observed in 2 hypertensive patients recovering from major surgery under spontaneous ventilation. Sinus rhythm was ascertained throughout the recording. These oscillations could not be linked one-to-one to ventilatory cycles.

Nonrespiratory Sinus Arrhythmia

American Journal of Critical Care, 2005
Scenario: This continuous lead II rhythm strip was obtained in a 25-year-old woman admitted to the intensive care unit for intracerebral hemorrhage. The patient presented to the emergency department with a headache after a skateboarding accident. The patient stated that she “bumped” her head during the accident.

SINUS ARRHYTHMIA

Pediatrics, 1960
Though there are many comments on respiratory sinus arrhythmia in articles and textbooks, there have been surprisingly few data collected. We have presented data from 4,096 electrocardiograms of 199 healthy individuals on pulse rate, range (max. difference in cycle length), and frequency index (range/mean cycle lengthx100).

Sinus arrhythmia in rheumatic fever

American Heart Journal, 1961
Abstract 1. 1. The degree (frequency index) of sinus arrhythmia was investigated in children suffering an initial attack of rheumatic fever (with and without carditis), in children with a recurrent attack, and in children with normal hearts who served as controls. 2. 2.

Arrhythmias and Sinus Node Dysfunction

JAMA: The Journal of the American Medical Association, 1984
To the Editor. — Alpert and Flaker1have contributed an excellent review of arrhythmias associated with sinus node dysfunction. I wish to take exception to only one item, which, unfortunately, is a recurring source of confusion in many publications. In the author's Table 1, they list acute pericarditis as a cause of sinus node dysfunction.

Analysis of vagally induced sinus arrhythmias

Journal of Theoretical Biology, 1992
Vagal stimulation at precise times in successive cardiac cycles can elicit sinus arrhythmias. Two mechanisms have been identified that can, but do not necessarily, cause these vagally induced sinus arrhythmias. First, changes in cycle length elicited by a given concentration of acetylcholine (ACh) depend on the phase of the pacemaker cell action ...

Respiration Sinus Arrhythmia in Psychotic Children

Psychophysiology, 1973
ABSTRACTTen psychotic and 10 normal children, paired for age and sex, were compared for respiratory sinus arrhythmia differences under conditions of spontaneous and 5, 10, and 15 sec interval breathing. Cardiac rate and respiratory changes were simultaneously recorded. Parameters of degree of change and timing for each respiratory‐cardiac cycle and its
