EsetismertetÉs: Egy 44 éves férfi betegnél endokarditisz talaján kialakult súlyos aortabillentyű-elégtelenség tett szükségessé szívsebészeti beavatkozást. A kevesebb mint egy év alatt bekövetkezett többszöri trombotikus esemény felvetette antifoszfolipid szindróma lehetőségét. A lupus antikoaguláns pozitivitás és az említett klinikai kép ezt igazolta.

Background: Evaluation of heart rate variability (HRV) detects the early subclinical alterations of the autonomic nervous system. Thus, impaired HRV is the earliest subclinical marker of cardiac autonomic neuropathy (CAN) in type 1 diabetes mellitus (T1DM).
Objectives: We aimed to explore the HRV parameters in asymptomatic T1DM patients and compare them with the results obtained in healthy subjects.
Article Synopsis
- The study aimed to evaluate the immediate impact of physical vascular therapy (PVT) on the autonomic nervous system using heart rate variability (HRV) and heart rate asymmetry (HRA) analysis in patients with coronary heart disease.
- A total of 48 patients participated, with half receiving actual PVT and the other half undergoing sham treatment, while their heart activity was monitored before, during, and after the therapy.
- Results showed that PVT notably improved certain HRV indices, indicating a positive autonomic response, whereas the sham treatment did not yield significant changes, highlighting the sensitivity of HRA in measuring these effects.
Precise beat-to-beat fiducial point detection in the photoplethysmogram signal is essential for reliable pulse rate variability (PRV) analysis, which is considered an integral part of health monitoring devices in the evolving era of mobile health. Several studies have aimed to compare PRV to the well-investigated, gold standard heart rate variability (HRV) analysis, to see if they are interchangeable. The agreement between PRV and HRV is not unequivocal, as we learn from the commented metaanalysis.

Background: Cardiac resynchronization therapy (CRT) is considered an efficient method to improve the left ventricular (LV) dysfunction with left bundle branch block. However, coronary venous anatomy is not appropriate in about 10% of the cases; thus other alternatives, such as epicardial lead implantation via minithoracotomy are needed.
Methods: During the period 2007-2017, a total of 57 patients were operated at our institute via left anterior minithoracotomy after an unsuccessful transvenous CRT.
