Efficacy of an implanted automatic defibrillator which had induced atrial fibrillation.
A 54 year old man with refractory life threatening ventricular tachycardia was given an automatic defibrillator. The initial system was a transvenous defibrillator coil electrode and this was later modified by implantation of two patch electrodes at thoracotomy. The modified system successfully controlled ventricular tachycardia. On one occasion reversion of ventricular tachycardia by the defib...
متن کاملImplanted Devices and Atrial Fibrillation
Atrial fibrillation (AF) is a supraventricular tachyarrhythmia characterized by uncoordinated atrial activation with consequent deterioration of atrial mechanical function. On the electrocardiogram (ECG), AF is characterized by the replacement of consistent P waves with rapid oscillations or fibrillatory waves associated with an irregular ventricular response. AF is the most common arrhythmia i...
متن کاملIs An Atrial Defibrillator Still An Option In Treating Patients With Atrial Fibrillation?
Atrial fibrillation (AF) is a common disorder associated with significant morbidities and presents several challenges for the control of symptoms and prevention of long-term implications. Atrial defibrillators (ADs), used for rhythm control in patients with symptoms refractory to medical therapy, can detect recurrences of the arrhythmia, allow prompt patient-directed treatment, and have the pot...
متن کاملAre electrophysiological changes induced by longer lasting atrial fibrillation reversible? :observations using the atrial defibrillator.
BACKGROUND Studies in animal hearts have shown shortening of the atrial effective refractory period (AERP) and loss of the relation between the AERP and heart rate after prolonged periods of atrial fibrillation (AF). The purposes of this study were (1) to evaluate atrial electrophysiology after a long period of sinus rhythm in patients who had longer lasting recurrent AF that was successfully t...
متن کاملLow efficacy of cardioversion of persistent atrial fibrillation with the implantable cardioverter-defibrillator
AIMS Atrial fibrillation (AF) and heart failure are conditions that often coexist. Consequently, many patients with an implantable cardioverter-defibrillator (ICD) present with AF. We evaluated the effectiveness of internal cardioversion of AF in patients with an ICD. METHODS Retrospectively, we included 27 consecutive ICD patients with persistent AF who underwent internal cardioversion using...
