The purpose of the present work is to establish a one-to-one correspondence between the family of interval type-2 fuzzy reflexive/tolerance approximation spaces and the family of interval type-2 fuzzy closure spaces.

Takotsubo cardiomyopathy is a rare type of nonischemic cardiomyopathy accompanied by a transient ballooning and akinesis of the apical segment of left ventricle. Here, we report a 28-year-old woman who presented with acute chest pain after an emotional stress. Electrocardiography showed STsegment elevation in leads II, III, aVF, V3-V6. Echocardiography, coronary angiography and left ventriculog...

Brugada syndrome is characterized by the presence of right bundle branch block on electrocardiography and by ST-segment elevation in the right precordial leads (V1-V3), by the absence of structural cardiac abnormalities, and by episodes of syncope or sudden death. On occasion, diagnosis is made difficult by temporary normalization of the ECG. The condition can be unmasked by potent sodium chann...

Abstract Background Moral injury exposure (MIE) and distress (MID) may indirectly affect the relationship between trauma alterations in autonomic regulation [assessed via high-frequency heart rate variability (hfHRV)] civilians, but this has not been tested prior research. We conducted two exploratory studies to examine types' associations with MIE MID among civilian medical patients (Study 1) ...

The use of dynamic electrocardiogram (ECG) monitoring is regarded as a standard of care during general anesthesia and is strongly encouraged when providing deep sedation. Although significant cardiovascular changes rarely if ever can be attributed to mild or moderate sedation techniques, the American Dental Association recommends ECG monitoring for patients with significant cardiovascular disea...

Over the past decade, significant advances were made in the research, diagnosis, and treatment of cardiovascular diseases. Such progress was in every sphere of cardiology that includes non-invasive, minimally invasive, and invasive technologies. Interpretive electrocardiography, cardiac pacemakers, cardiac stents, and angioplasty are some areas where the progress has been significant. Non-invas...

In 1908, Einthovent published the first example of normal electrocardiographic responses to exercise. In 1928, Feil and Siegel2 observed abnormal downsloping ST depression and T wave inversion in three of four patients experiencing anginal attacks (presumably after climbing stairs to the phy-sician's office; H. Hellerstein, personal communication). In 1932, Goldhammer and Scherf3 associated thi...

situation resembling most electrophysiological studies. One other factor in favour of subpectoral automatic cardioverter/defibrillator implantation under local anaesthesia is the reduced complexity of the implant procedure, whereby the procedure-related risk for the patients is reduced, since the complication rate during a pacemaker-like approach of automatic cardioverter/ defibrillator implant...
