We would like to thank Dr. Imamura for their interest in our study and their valuable comments on diagnostics and risk stratification in Brugada syndrome (BrS) [..

Twelve-Lead ECG, Holter Monitoring Parameters, and Genetic Testing in Brugada Syndrome: Insights from Analysis of Multigenerational Family with a History of Sudden Cardiac Arrest during Physical Activity.

Brugada syndrome (BrS) is an arrhythmogenic disorder increasing the risk of syncopal episodes and sudden cardiac death. BrS usually runs through families with reduced penetrance and variable expression. We analyzed the multigenerational family of a patient who died after sudden cardiac arrest with post-mortem diagnosis of BrS.

Cardiac chambers perforation by pacemaker and cardioverter-defibrillator leads. Own experience in diagnosis, treatment and preventive methods.

Cardiac chamber perforation is an uncommon, but potentially dangerous, complication of implantation of a pacemaker (PM) or a cardioverter-defibrillator (ICD). Different clinical presentations are related to the time between implantation and perforation, localisation of the perforation and concomitant lesions in neighbouring organs. Diagnosis is based on concomitant analysis of the clinical picture, ECG tracings, PM or ICD function check-up with a programmer, and review of echocardiographic, X-ray and computed tomography pictures.

Influence of heart failure etiology on the effect of upgrading from right ventricular apical to biventricular or bifocal pacing in patients with permanent atrial fibrillation and advanced heart failure.

Introduction: Chronic heart failure (HF) results from various disease processes. There are no data on the effect of the etiology of HF on the improvement after pacemaker upgrade. OBJECTIVES The aim of the study was to assess changes in various parameters in patients with ischemic (IC) and nonischemic (NIC) cardiomyopathy after pacemaker upgrade in pacemaker-dependent patients with permanent atrial fibrillation, in the course of advanced HF during 12-month follow-up.

[AAI stimulation and nodal rhythm].

We describe the case of a 77 year-old white woman treated by AAI pacing. Nodal rhythm with ventriculo-atrial conduction and retrograde P wave were observed in ECG Holter monitoring. The retrograde P wave was sensed by the pacemaker, which responded correctly.

[Echocardiographic examination in patients with corrected transposition of great arteries (L-TGA, ccTGA) with failure of systemic (anatomically) right ventricle treated with resynchronisation therapy].

A congestive heart failure is common in population of adult patients with congenital heart disease, especially among patients with systemic right ventricle. According to literature 4-9% of patients with systemic right ventricle can be treated with resynchronisation therapy (CRT). Authors present results of echocardiographic examination in two patients with ccTGA treated by CRT because of failure of systemic right ventricle.

Percutaneous removal of endocardial implantable cardioverter-defibrillator lead displaced to the right pulmonary artery.

We describe a case of percutaneous removal of endocardial implantable cardioverter-defibrillator lead displaced to the right pulmonary artery. The procedure was performed from two accesses; from the lower one (femoral) and then, due to technical problems, from the upper one (subclavian). In the last stage the flattened Dotter's basket was introduced to the heart inside the Byrd dilator and then fastened to the described lead as the external 'splint'.

[Necessity of endocardial lead removal in device upgrade in a patient with left subclavian vein occlusion - a case report].

We describe a method of regaining venous access to the heart in a patient with permanent atrial stimulation, in whom the pacing system upgrade to the atrio-ventricular one was necessary. However, left subclavian vein occlusion was found. We used an existing lead as a conduit.

[Pacemaker implantation in a patient with cor triatriatum sinister - preoperative evaluation].

A case of 72 year old-male with cor triatriatum sinister, permanent atrial fibrillation and symptomatic bradycardia is presented. Patient was scheduled for pacemaker implantation. A preoperative evaluation with transesophageal echocardiography revealed a nonrestrictive membrane in left atrium, normal right superior vena cava and absence of persistent left superior vena cava and other cardiac anomalies.

[The impact of nitrates and mono-therapy and nitrates combined with angiotensin converting enzyme inhibitors on left ventricular remodeling and exercise capacity in patients after acute myocardial infarction].

The objective of this paper was to evaluate potential beneficial effects of combined treatment with slow-release nitrates and angiotensin converting enzyme inhibitors (ACE) on left ventricular remodeling and exercise capacity in patients after acute myocardial infarction. In this study, 141 patients (aged 34 to 74, mean 56.6 years) with sufficient circulation received combined treatment with 24 hour nitroglycerin infusion followed by oral nitrates (isosorbide mononitrate 50 mg OD) from day 2 day 42 after myocardial infarction and ACE inhibitor (captopril 25 mg BID or enalapril 5 mg BID versus placebo) from day 10 to day 42.
