High-Resolution Body Surface Potential Mapping in Exercise Assessment of Ischemic Heart Disease.

Standard 12-lead ECG exercise testing is commonly used for screening of ischemic heart disease (IHD). We studied if high-resolution body surface potential mapping (HR-BSPM) during exercise offers advantages over current standards in noninvasive evaluation of IHD. This study was carried out on 90 IHD patients and 33 healthy controls.

Prolonged postocclusive hyperemia response in patients with normal-tension glaucoma.

Background: It is believed that endothelial dysfunction may be a link between systemic and ocular dysregulation in glaucoma. The aim of this study was to evaluate peripheral vascular reactive hyperemia in response to occlusion test and to correlate peripheral vascular findings with retrobulbar hemodynamics parameters in patients with normal-tension glaucoma.

Material And Methods: Forty-eight patients with normal-tension glaucoma (mean age 58.

Evaluation of the QRS-T angle using the high-resolution 64-lead electrocardiography.

Objective: The aim of the study was to evaluate the influence of the number of electrocardiogram (ECG) leads on the diagnostic value of TCRT (spatial QRS-T angle) parameter (12 standard ECG leads and 61 surface ECG leads were used). The TCRT parameter, which describes the spatial QRS-T angle, is a useful indicator of the risk of ventricular tachycardia (VT) and sudden cardiac death (SCD). It is usually calculated from standard 12 leads ECG.

Microcirculation in the diabetic foot as measured by a multichannel laser Doppler instrument.

Background: The purpose of this study was to investigate microvascular perfusion in insulin-dependent diabetic patients at various locations on the foot, and to determine which part of the foot is most sensitive to microangiopathic changes. All the parameters of postocclusive reactive hyperemia calculated from multichannel laser Doppler recordings were also evaluated to find the most valuable measure for diabetes examination.

Material/methods: Our study involved 65 subjects divided into four subgroups: male and female controls, and male and female IDDM patients without overt complications.
