Background: Although telemedicine has been proven to have significant potential for improving care for patients with cardiac problems, there remains a substantial risk of introducing disparities linked to the use of digital technology, especially for older or socially vulnerable subgroups.
Objective: We investigated factors influencing adherence to a telemedicine-delivered health education intervention in patients with ischemia, emphasizing demographic and socioeconomic considerations.
Methods: We conducted a descriptive, observational, prospective cohort study in consecutive patients referred to our cardiology center for acute coronary syndrome, from February 2022 to January 2023.
SCN5A mutation is associated with a higher Shanghai Score in patients with type 1 Brugada ECG pattern.

Article Synopsis
- Brugada syndrome (BrS) is a genetic heart condition that can lead to severe heart issues and sudden cardiac death, characterized by a specific ECG pattern.
- This study evaluated the Shanghai Score System's effectiveness in predicting the presence of SCN5A mutations in 125 BrS patients, showing that higher scores were linked to these mutations.
- Results indicated that SCN5A mutations were associated with longer PR and QRS intervals on ECGs, reinforcing the relevance of the Shanghai Score in clinical settings for identifying patients who may benefit from genetic testing.
Although ultrasound-guided axillary vein access (USGAVA) has proven to be a highly effective and safe method for cardiac electronic implantable device (CIED) lead placement, the collapsibility of the axillary vein (AV) during tidal breathing can lead to narrowing or complete collapse, posing a challenge for successful vein puncture and cannulation. We investigated the potential of the Valsalva maneuver (Vm) as a facilitating technique for USGAVA in this context. Out of 148 patients undergoing CIED implantation via USGAVA, 41 were asked to perform the Vm, because they were considered unsuitable for venipuncture due to a narrower AV diameter, as assessed by ultrasound (2.

Both the noise spectrum and temporal correlations are diagnosed by probing the photon with frequent (partially) selective polarization measurements. We show that noise with positive temporal correlations corresponds to our single photon undergoing a dynamical regime enabled by the quantum Zeno effect (QZE), whereas noise characterized by negative (anti) correlations corresponds to regimes associated with the anti-Zeno effect (AZE).

- A study was conducted to evaluate the use of handheld ultrasound devices (HUD) for guiding axillary vein access during cardiac device implantation, comparing it to the traditional fluoroscopy method.
- The results showed similar success rates, complication rates, and procedure times between the two methods, but the HUD group had significantly reduced X-ray exposure time.
- The study concluded that using a HUD for this technique is effective, safe, and minimizes radiation exposure while maintaining efficiency in the implantation process.
