it has been shown in elegant anatomic studies that acute pericarditis does not invade the sinus node proper, although it can infiltrate the zone around it.2Moreover, LeKieffre and colleagues2assert that at postmortem examination they have "never seen a patient with pericarditis and arrhythmia who...

Sinus arrhythmiais a normal physiologic arrhythmia that occurs at slow resting heart rates and is associated with variation in the rate of discharge from the SA node associated withvariation in the intensity of vagal stimulation. Sinus arrhythmia is most oftencorrelated with respirationso that the dis...
Sinus Arrhythmia Description.There is a phasic variation in the heart rate caused by respiratory influences on the autonomic nervous system, increasing during inspiration and decreasing during expiration. Thearrhythmiaoccurs, with maintenance of characteristics ofsinus rhythm(seeFig. 24-1). ...
Rapid electrolyte shifts, particularly calcium and potassium, and transient direct myocardial damage may also contribute to the development of arrhythmia [2], [6]. Bradycardia secondary to steroid administration is often asymptomatic and may go unnoticed. Patients' heart rates usually improve with ...

When rhythm control therapy is indicated, the choice of antiarrhythmic medication should be dictated by the presence or absence of structural heart disease, congestive heart failure, renal dysfunction, or other comorbidities in order to maximize efficacy and minimize the chance of proarrhythmia or ...
