conclusions this case report underscores the role of fetal echocardiography in the prenatal diagnosis of cardiac disease and illustrates rhabdomyomas in a tuberous sclerosis patient. rhabdomyomas are histologically benign; however, they may cause severe arrhythmia even when they are regressing. case presentation our tuberous sclerosis patient developed arrhythmia unexpectedly while his tumors w...

torsades de pointes is a rare but potentially lethal arrhythmia which mainly occurs in the setting of a prolonged qt interval. ecg is a reliable tool to detect such abnormalities, routinely taken from all patients over 40 who undergo surgery. we describe the case of a 35-year-old woman with torsades de points arrhythmia after hysterectomy surgery. most likely, our patients had long qt syndrome ...

PURPOSE To describe the illness experience of patients living with arrhythmia and implantable cardioverter defibrillator (ICD) and evaluate their experience after implantation of the device for gaining insight on care suitable for their condition. METHODS In this qualitative descriptive study, we conducted semi-structured interviews of 22 outpatients who were visiting certified implant facili...

An 18 year old girl presented with frequent vasovagal attacks and sinus arrhythmia. The amplitude of respiratory sinus arrhythmia assessed by cosinor analysis was 20%; the predicted value for a normal girl of this age is 4% and the 95% confidence interval is 0-8%. Treatment with propantheline, in a dose sufficient to reduce the amplitude of sinus arrhythmia to normal, abolished her symptoms.

Background: Tricyclic antidepressants (TCAS) Poisoning is the most common poisoning in the Poisoning Emergency Department of Noor Hospital, Isfahan, Iran. The objective of this study was to compare QRS interval duration with RaVR³3mm and R/SaVR³ 0.7 in predicting: serious complications of acute TCA toxicity. Methods and Materials: This study was descriptive – analytic and prospective cohort....

The aim of this study is to address a new feature extraction method in the area of the heart arrhythmia classification based on a metric with simple mathematical calculation called Curve-Length Method (CLM). In the presented method, curve length of the under study excerpted segment of signal is considered as an informative feature in which the effect of important geometric parameters of the ori...

Heart rate increases during inspiration and slows during postinspiration; this respiratory sinus arrhythmia helps match pulmonary blood flow to lung inflation and maintain an appropriate diffusion gradient of oxygen in the lungs. This cardiorespiratory pattern is found in neonatal and adult humans, baboons, dogs, rabbits, and seals. Respiratory sinus arrhythmia occurs mainly due to inhibition o...
