Abstract

Paroxysmal palpitation is a frequent non-specific symptom observed in clinical practice. It is not always possible to identify the arrhythmogenic cause of this complaint. The induction of paroxysmal atrial fibrillation (PAF) during transoesophageal pacing (TEP) was found to be particularly useful when arrhythmia paroxysms were not evidenced by standard electrocardiography or by 24-hour Holter monitoring. The objective of the present study was a comparative assessment of the electrophysiological parameters obtained from a patient group with PAF induced during TEP and from a patient group with no arrhythmia, in order to determine the hazard of spontaneous PAF occurrence. The study included 116 patients complaining of palpitations who underwent TEP. Of these, 53 were selected (34 males and 19 females; mean age, 47.6 +/- 13.1) in whom a sustained PAF episode (> 30 sec) had been induced during TEP. These patients are referred to Group I. Group II (control) comprised the remaining 63 patients (38 males and 25 females; mean age 45.5 +/- 8.5) in whom no PAF episode had been induced during TEP. All patients (Group I and Group II) underwent echocardiography, 24-hour Holter monitoring, exercise test and TEP. During TEP the following param...Continue Reading

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
