Bradyarrhythmias are commonly encountered in clinical practice. While there are several electrocardiographic criteria and algorithms for tachyarrhythmias, there is no algorithm for bradyarrhythmias to the best of our knowledge. In this article, we propose a diagnostic algorithm that uses simple concepts: (1) the presence or absence of P waves, (2) the relationship between the number of P waves and QRS complexes, and (3) the regularity of time intervals (PP, PR and RR intervals). We believe this straightforward, stepwise method provides a structured and thorough approach to the wide differential diagnosis of bradyarrhythmias, and in doing so, reduces misdiagnosis and mismanagement.

Background/objectives: Newborn heart rate is an integral part of resuscitation algorithms, but the impact of ECG monitoring on resuscitative interventions and clinical outcomes has been identified as a knowledge gap. The objective was to evaluate the impact of routine use of dry-electrode ECG in all newborns immediately after birth on time to start positive pressure ventilation (PPV) when indicated.
Methods: We conducted a randomized clinical trial from June 2019 to November 2021 at Stavanger University Hospital, Norway.

Dexmedetomidine (DEX), as a widely used medication for sedation, its usage has increased significantly. The concerns about its side effects remain, making a thorough safety evaluation necessary. Data on adverse drug events related to DEX from the first quarter of 2004 to the fourth quarter of 2023 were collected from the US Food and Drug Administration.

Background: Conduction system pacing, particularly left bundle branch area pacing (LBBAP), is emerging as the preferred strategy for bradyarrhythmias and cardiac resynchronization therapy because of its clinical benefits. However, the differences in the impact of LBBAP vs right ventricular pacing (RVP) on cardiac energetics remain unclear.
Objective: The purpose of this study was to compare the effects of LBBAP and RVP on cardiac energetics using a novel noninvasive pressure-volume (PV) loop algorithm derived from cardiac magnetic resonance (CMR).

This paper presents a novel privacy-preserving architecture, a fusion of Federated Learning with Personalized Models and Differential Privacy (FLPMDP), for diagnosing arrhythmia from 12-lead electrocardiogram (ECG) signals. The architecture supports collaborative training in decentralized healthcare institutions without exposing sensitive patient information. By employing gated recurrent units (GRUs) for temporal sequence modeling along with feature fusion techniques and local differential privacy enforcement, FLPMDP ensures robust classification performance with data confidentiality.
