Esophageal long-term ECG reveals paroxysmal atrial fibrillation.
A 79-year-old man was referred for coronary angiography because of atypical chest pain. The patient’s medical history included a myocardial infarction 5 years previously and well-controlled arterial hypertension. Three months before this admission he reported atypical chest pain, sometimes associated with palpitations lasting seconds up to a few minutes. Hence, he underwent ambulant 24-hour ECG...
متن کاملAtrial ectopic activity associated with sinus bradycardia.
Five cases of atrial ectopic activity associated with sinus bradyeardia are reported. The ectopic activity was abolished in all cases when the sinus rate was increased spontaneously or by atropine. The report demonstrated that the incidence of ectopic activity increases in the atrium at the slower basic rates as it does in the ventricle. It was emphasized that atrial ectopic activity associated...
متن کاملLong-term pervenous atrial pacing.
Long-term pervenous right atrial pacing has been used in five patients with intact atrioventricular (A-V) conduction for the treatment of refractory ventricular arrhythmias in two subjects and marked sinus bradyeardia in three, two of whom also had paroxysmal supraventricular arrhythmias. The pervenous method was used to avoid a thoracotomy, and atrial pacing was chosen over ventricular pacing ...
متن کاملNonlinear Analysis of Electrocardiography Signals for Atrial Fibrillation
This paper aims to analyze the electrocardiography (ECG) signals for patient with atrial fibrillation (AF) by using bispectrum and extreme learning machine (ELM). AF is the most common irregular heart beat disease which may cause many cardiac diseases as well. Bispectral analysis was used to extract the nonlinear information in the ECG signals. The bispectral features of each ECG episode were d...
متن کاملLong-term follow-up of atrial myxoma.
Experience of I2 patients with atrial myxoma over a period of Io years is reviewed. Eleven patients had a left atrial tumour and one a right atrial tumour. Successful surgical removal was carried out in 9 (8 left, and I right). Three patients died before operation, the diagnosis having been made in life in 2 of them. Seven patients with left atrial myxoma have been followed for 5 to Io years af...
