In this paper I endeavored to show that respiratory sinus arrhythmia closely corresponds with the perception of psychosomatic complaints. To achieve this aim, two groups of menopausal women, each consisting of 85 subjects, were compared, one of which exhibiting troubles with falling asleep, frequent awakening at night, and sweating and fatigability sensations during the day and the other being ...

The sinus of Valsalva presents the initial segment aorta from where coronary vessels arise. Sinus aneurysms (SOVAs) present as progressive dilatation aortic sinus. SOVA arises both congenital and acquired weakness elastic lamina media. Though most SOVAs are asymptomatic diagnosed on screening for other pathologies, patients can with symptoms arrhythmia, insufficiency, aorto-cardiac fistulas, an...

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. Cardioversion for AF may be performed by either using direct current (DC) shock (electrical cardioversion) or using drugs (chemical cardioversion). Here we report a case of a patient with heart failure and AF, who reverted to the normal sinus rhythm on correction of hyperkalemia (electrogenic cardioversion). The patien...

In pulmonary stenosis with normal aortic root, sinus rhythm is the rule and atrial fibrillation appears to be rare (Abrahams and Wood, 1951; Campbell, 1954; Donzelot and D'Allaines, 1954; Kjellberg et al., 1955). The following case is considered to be of interest because the presence of this arrhythmia resulted in a clinical picture differing in several respects from that of pulmonary stenosis ...

Atrial fibrillation (AF) is a common arrhythmia that occurs in paroxysmal and persistent forms. It occurs in varied situations but lightning induced AF is extremely rare. Here is a case which reverted to sinus rhythm spontaneously. This 37-year-old man without any underlying heart disease had new onset AF after being struck by a lightning. Oral Metoprolol alone was given to control ventricular ...

Atrial fibrillation (AF) is a ubiquitous yet diverse cardiac arrhythmia whose incidence increases with age; with most forms of cardiac and some pulmonary diseases; and with a number of metabolic, toxic, endocrine, or genetic abnormalities.1,2 Classification of clinical AF subtypes can be achieved on the basis of the ease by which episodes of the arrhythmia terminate as follows3: “Paroxysmal” AF...

This study focuses on the dynamic pattern of heart rate variability in the frequency range of respiration, the so-called respiratory sinus arrhythmia. Forty experimental time series of heart rate data from four healthy adult volunteers undergoing a paced respiration protocol were used as an empirical basis. For pacing-cycle lengths >8 s, the heartbeat intervals are shown to obey a rule that can...

Acute myocardial infarction complicated with lethal cardiac arrhythmia remains the major cause of sudden death. The possible clinical presentation leading to lethal ventricular arrhythmia has been demonstrated but the data are limited. The previous study revealed no significant correlation between sudden cardiac death and the location of coronary obstruction site. And the possible mechanism of ...
