The feasibility of fully automated pacemaker advise in treating atrial tachyarrhythmias.

Background: Modern pacemakers continuously store significant cardiac-related events. Interpreting these data and reprogramming the pacemaker can be time-consuming and demands expert knowledge. A software-based expert system, the therapy advisor (TA), was developed, which analyzes stored data and provides reprogramming recommendations.

Compliance to MADIT and MUSTT criteria for implantable cardioverter defibrillator therapy in the pre-SCD-Heft and MADIT II era. Data from a multicenter Italian study.

The follow-up of 1440 consecutive post-MI patients (68.9 ± 10.9 years) with an LVEF ≤ 40% was analyzed in 19 Italian hospitals to evaluate how many patients with clinical nonsustained VT and inducible sustained VT or VF underwent post-discharge risk assessment (RA).

Early EPS/ICD strategy in survivors of acute myocardial infarction with severe left ventricular dysfunction on optimal beta-blocker treatment. The BEta-blocker STrategy plus ICD trial.

Aims: This multicentre prospective randomised trial was undertaken to evaluate the usefulness of an electrophysiological study (EPS)-guided/implantable cardioverter defibrillator (ICD) strategy in patients at high risk of sudden death (SD) early after myocardial infarction (MI). Previous studies have shown the benefits of such a strategy only in high-risk patients late after MI.

Methods And Results: We enrolled 143 survivors of acute MI (<1 month) with left ventricular ejection fraction < or = 35% and either frequent (> or =10/h) premature ventricular complexes (PVCs), or depressed heart rate variability (SDNN < 70 ms) or abnormal signal-averaged ECG, who were able to tolerate optimised beta-blocker therapy (68 +/- 40 mg/day of metoprolol).

Atrial fibrillation requiring urgent medical care. Approach and outcome in the various departments of admission. Data from the atrial Fibrillation/flutter Italian REgistry (FIRE).

Background: The atrial Fibrillation/flutter Italian REgistry (FIRE) study was designed to obtain updated information regarding the clinical characteristics of and medical approach to patients requiring urgent medical care for atrial fibrillation (AF) or atrial flutter in a nationwide and representative series of hospitals.

Methods: 4570 consecutive patients admitted to the emergency room for AF/atrial flutter were enrolled in 207 hospitals. Of these, 2838 (61.

Combined use of morphology discrimination, sudden onset, and stability as discriminating algorithms in single chamber cardioverter defibrillators.

Morphology Discrimination (MD) is a rhythm discriminator based on QRS morphology analysis that can be combined with other discriminators like Stability, with or without Sinus Interval History (SIH) and Sudden Onset. Thirty-five patients implanted with a St. Jude Medical single chamber ICD were evaluated during exercise testing, during induced AF, and during follow-up for 14 +/- 5 months.
