Patient perspective and safety of remote monitoring of implantable cardioverter-defibrillators in the Polish Nationwide Multicenter Registry: the Medtronic CareLink network evaluation.

Background: Remote monitoring of cardiovascular implantable electronic devices allows the assessment of system effectiveness, arrhythmia occurrence, and indirectly, clinical changes. Medical interventions can be performed earlier because of a faster transfer of information to the monitoring site, even in the case of asymptomatic arrhythmias or abnormalities in the operation of the system.

Aims: The aim of the study was to assess the effectiveness of remote monitoring of implantable cardioverter-defibrillators and evaluation in an outpatient setting during 12-month follow -up.

Effects of amiodarone on the P-wave triggered signal-averaged electrocardiogram in patients with paroxysmal atrial fibrillation and coronary artery disease.

The effects of a 6-week treatment with amiodarone on the P-wave triggered signal-averaged electrocardiogram in patients with paroxysmal atrial fibrillation and coronary artery disease have been studied. Amiodarone favorably influences P-wave triggered signal-averaged electrocardiographic parameters, predominantly in patients in whom amiodarone is effective in preventing paroxysmal atrial fibrillation.

[Evaluation of electrophysiologic properties of the heart atrium in patients with electrically induced atrial fibrillation].

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 influence of myocardial ischemia on the electrocardiogram under stress].

Ventricular late potentials (LP) seem to reflect mixed, anatomic and electrophysiologic substrate for ventricular reentrant tachyarrhythmias. Ischemic events can perform areas of delay and dispersion of conduction and refractoriness in patients with ischaemic heart disease (CAD), especially after myocardial infarction (MI). These electrophysiological disturbances can induce the reentry phenomenon.
