Opis:
This article demonstrates the echocardiographic method to assess the placement of pacemaker and implantable cardioverter-defibrillator leads in the vicinity of the superior vena cava as a way to increase the safety of transvenous lead extraction (TLE). Three-dimensional transesophageal echocardiography was performed in 3 patients during TLE with the use of the Specranetics Excimer Laser device. We assessed the following parameters: lead adherence to the lateral wall of the vessel and lead movement. This method increased the safety of the performed TLE.

Opis:
Introduction: Syncope is defined as transient loss of consciousness, due to decrease in brain perfusion. The most frequent mechanism is vasovagal syncope. In many patients, the cause of syncope remains unspecified, despite an extensive diagnostic work-up. Tilt-test (TT) is an acknowledged diagnostic tool for syncope. Currently, the so-called Italian protocol of TT is most widely used. Vasovagal syncope is caused by impaired circulatory regulation in response to orthostatic stress. One of the available tools to examine the influence of the nervous system on the circulation is the analysis of heart rate variability (HRV). Despite numerous publications concerning HRV parameters and autonomic regulation in patients with syncope, direct comparisons and metaanalysis of the results is impossible, due to variability of TT protocols and study group specifications. Aim of the study: As there is no uniform model of HRV during TT, we aimed to analyze HRV parameters during TT (performed according to the Italian protocol) in patients with vasovagal syncope, in order to determine the possible application of HRV measurements in clinical practice in that group of patients. Detailed objectives were: (1) analysis and comparison of HRV in patients with and without the history of syncope; (2) analysis of HRV changes in consecutive stages of TT; (3) identification of possible HRV differences between patients with positive and negative TT results. Materials and methods: Patients between 18 and 50 years of age were qualified for the study, if they had a history of at least 2 incidents of syncope or presyncope within the preceeding 6 months, and if signs and symptoms indicated the vasovagal mechanism. The study group included 150 patients: 100 consecutive patients with a postive TT result (POS), and 50 consecutive patients with a negative TT result (NEG). The control group (CG) comprised 50 volunteers with no history of syncope nor presyncope, matched according to age and sex to the study group. In all patients a TT was performed according to the Italian protocol, with paced breathing at a rate of 15/min. Time-domain (meanRR, SDNN, RMSSD, pNN50) and frequency-domain (abs_LF, abs_HF, rel_LF, rel_HF, norm_LF, norm_HF, LF/HF) HRV parameters were analyzed and compared at different stages of TT in the study groups as specified above. Results: 100 patients at the age of 18-44 years were included in the POS group, 50 patients at the age of 18-39 years in the NEG group, and 50 volunteers at the age of 20-39 in the CG. Volunteers in the control group developed unexpectedly high percentage of positive TT (14 patients). For consistency of analysis, the CG was thus subdivided according to the result of the TT into CG_POS (positive result of TT) – 14 patients, and CG_NEG (negative result of TT) – 36 patients. Based on HRV analaysis, no significant differences in HRV values were noted between patients with a history of syncope and positive or negative result of TT. Upright tilt resulted in HRV changes of the same direction and value in syncopal patients in the POS and NEG goup, as well as in patients in the CG_NEG group. Conclusion: HRV values and changes of those values at subsequent stages of TT were not different between syncopal patients with postive or negative TT result, or negative TT control group. The Italian protocol of TT may be associated with a surprisingly high percentage of false positive results.

Implantable cardiac electronic device (ICED) infections include- lead infection (ICED-LI), device pocket infection (PI) and infective endocarditis (ICED-IE). The aim of this study is to analyze the records of patients with ICED, who developed implantable device-related infections. We analyzed retrospectively the records of the University Clinical Centre (Gdańsk) patients who in 2012-2018 underwent transvenous lead extraction (TLE) due to infections. In order to identify potential ICED infection risk factors we included patients who underwent any electrotherapy procedure within 2 years prior to the TLE. ICED infections that led to septic shock were defined as severe. The analyzed sample included 59 patients with infectious complications (37 male and 22 female) with median age of 74. The in-hospital mortality was 8.5%. All patients with severe ICED infection were diagnosed with ICED-LI, whereas the rest of the sample was diagnosed mostly with PI (p<0.001). The most commonly cultured pathogens were S. aureus and S. epidermidis. In the analyzed sample, the most common infectious complication related to the ICED was PI and the most common etiological agents were S. aureus and S. epidermidis. Severe ICED infections that present with septic shock are associated with a 50% in-hospital mortality rate.

Opis:
Background: Anatomy assessment using Computer Tomography (CT) and Magnetic Resonance (MRI) is performed in patients undergoing pulmonary vein isolation (PVI). The aim of this analysis was to investigate whether electroanatomical 3D map and CT/MRI image integration using the CartoMerge system improves efficacy, reduces procedure time or fluoroscopy usage. Materials and methods: 57 patients undergoing PVI were divided in two groups: “Merge” (n=45 pts) and “non-Merge” (n=14 pts) depending on usage of image integration. PV isolation during procedure (acute PVI), procedure time, fluoroscopy time, number of radio frequency (RF) applications and AF recurrence during follow-up (Merge group: 12-24 months, non-Merge group: 9-18 months) were analyzed. Results: Intra-procedural PVI was equal in both groups (93%). Long-term efficacy, defined as absence of AF recurrence, was insignificantly higher in the Merge group (69,8% vs 50%, p=0,11793). Procedure time was significantly longer in the Merge group – 239,1 (±55,5) min. vs 192,4 (±44,5). Fluoroscopy time was similar in both groups 29,9 (±12,23) vs 24,6 (±26,5) min, (p=0,579). Number of RF applications was significantly higher in the Merge group 48,5 (±25,2) vs 27,2 (±14,9). Conclusions: CartoMerge did not improve the rate of acute PVI, long-term effectivity or fluoroscopy time. In the non-Merge group the procedure time was shorter and the number of applications was significantly smaller.

Opis:
Telemedicine is very promising way of delivering medical services. At this moment telecardiology gives many possibilities of improving outcome of patient and very often it also decreases the costs, which makes it cost-effective solution. Unfortunately actually in Poland there are many difficulties in delivering telemedicine. There is no central refunding of procedures; hospitals are not ready with IT solutions etc. The article describes those problems in different fields of telecardiology.

Opis:
The paper examines the impact of the COVID-19 pandemic on macroeconomic activity in the selected European countries. The studies are based on monthly and quarterly indicators of GDP, unemployment rates and key indicators of the tourism sector. To present how COVID-19 has affected these macroeconomic variables, statistic data from the three periods are compared. Namely, data are collected from the pre-pandemic period, i.e. the fourth quarter of 2019 as the reference period, the second period covers the first quarter of 2020 and means the beginning of the pandemic, and the third one covers second quarter of 2020, during which the pandemic has spread to all the analyzed countries. The following statistical techniques are used in the research: regression analysis, the hierarchical grouping of agglomerations, k-means method, and selected non-parametric tests (Kruskal-Wallis test for a selected group of countries and Kolmogorov-Smirnov test for a selected pair of countries). The results show the significant impact of the pandemic on the level of gross domestic product, unemployment rate and turism sector. In most cases, a correlation between incidence of COVID-19 infections, unemployment rate and GDP is observed. The statistical techniques also allow to demonstrate the similarities and differences in the response of the economies to the COVID-19 pandemic. Central Statistical Offices of the selected countries are the main data source and for all calculations Statistica version 13.3. is used.
