Clinical data: the patient had a good clinical course after repair of severe coarctation of the aortic isthmus with end‑to‑end technique, closure of the interventricular communication at 18 days of life, and relief of moderate subaortic stenosis at 3 years of age. Currently, the patient can tolerate well routine exercise, with no symptoms. At last evaluation, blood pressure in the right arm was...

AIM The occurrence of accelerated junctional rhythm during radiofrequency energy delivery at the region of the slow pathway is a well-recognized marker of successful treatment of atrioventricular nodal re-entry tachycardia (AVNRT). Our aim was to evaluate if the quantity and duration of accelerated junctional rhythm during radiofrequency ablation of the slow pathway is correlated with residual ...

The newly described slow cortical rhythm (approximately 0.3 Hz), whose depolarizing-hyperpolarizing components are analyzed in the preceding article, is now investigated from the standpoint of its relations with delta (1-4 Hz) and spindle (7-14 Hz) rhythmicity. Regular-spiking and intrinsically bursting cortical neurons were mostly recorded from association suprasylvian areas 5 and 7; fewer neu...

BACKGROUND Heart failure (HF) is a syndrome that leads to poor outcome in advanced forms. The neurohormonal blockade modifies this natural history; however, it is often suboptimal. OBJECTIVE The aim of this study is to assess at what percentage cardiologists used to treating HF can prescribe target doses of drugs of proven efficacy. METHODS A total of 104 outpatients with systolic dysfuncti...

PURPOSE To assess the presence and the prevalence of arrhythmias and the variability of the heart rate in the medium-term postoperative period following the maze procedure for chronic atrial fibrillation (AF). METHODS Seventeen patients with a mean age of 51.7 +/- 12.9 years, who previously underwent the maze procedure without cryoablation for chronic atrial fibrillation, were evaluated with ...

A 37-year-old male patient was referred to our cardiology division with a longstanding and worsening history of short episodes of dizziness and reduced effort tolerance. He denied any syncope, palpitations or chest pain. His medical history was unremarkable and he took no medication. Family history was negative for cardiac diseases at a young age or premature sudden death. On clinical examinati...

AIMS Children with congenital complete atrioventricular block (CCAVB) often need pacemaker therapy. In these children, it may be preferable to use single-lead VDD pacing, but for VDD pacing a normal sinus node function is required. Our aim was to study sinus node function in children with CCAVB. METHODS AND RESULTS We longitudinally evaluated sinus rate in 36 children with CCAVB and normal an...

PURPOSE To develop an arrhythmia-insensitive rapid (AIR) cardiac T1 mapping pulse sequence for quantification of diffuse fibrosis. METHODS An arrhythmia-insensitive cardiac T1 mapping pulse sequence was developed based on saturation recovery T1 weighting, which is inherently insensitive to heart rate and rhythm, and two single-shot balanced steady-state free precession image acquisitions with...

AIMS To analyse whether heart rate may affect the efficacy of adenosine, verapamil and carotid sinus massage in terminating symptomatic episodes of paroxysmal supraventricular tachycardia (PSVT) in adults. METHODS AND RESULTS The study population was selected among 175 adult patients, affected by symptomatic PSVT. One hundred and six of them were considered eligible for the study. Each subjec...
