Summary: The study evaluated atrial electromechanical delay (AEMD) in patients with Chronic Obstructive Pulmonary Disease (COPD) using both ECG and echocardiography. Both mild and severe COPD groups showed decreased P-wave dispersion (PWD), increased tricuspid PA, and significantly decreased interatrial and right intra-AEMD times compared to the control group.

Summary: "This study computationally assessed the impact of variations in ion channel conductance on cardiac electromechanical delay (EMD), finding that major ion channels such as CaL play a crucial role in prolonging EMD. Moreover, ventricular cells with long EMD showed inferior mechanical responses due to reduced intracellular calcium levels, potentially compromising heart pump function."

Summary: This study assessed P-wave duration and dispersion in morbidly obese young subjects without co-associated atrial fibrillation risk factors, finding significantly prolonged P-wave duration and dispersion in obese patients compared to normal weight individuals, with a significant correlation with BMI. These results suggest that even in the absence of atrial fibrillation risk factors, severe obesity itself may lead to abnormal cardiac electrophysiological parameters.

Summary: This study reports a novel electromechanical metamaterial called SEMM, which utilizes its electromechanical resonant effects to achieve enhanced and tunable damping properties. The scissor-like structure in SEMM amplifies the damping ratio through a displacement amplification mechanism, improving vibration mitigation. By quantifying the relative dissipation performance based on complex band structures, SEMM demonstrates higher damping performance compared to traditional systems through numerical verification and analysis. The electromechanical nature of piezoelectric material in SEMM allows for convenient tuning of the damping properties by adjusting the piezoelectric shunting circuit.

Summary: This study assessed atrial conduction time and P-wave dispersion in patients with gestational diabetes mellitus (GDM) and compared them to a healthy pregnant control group. The results showed that GDM patients had higher P-wave dispersion and atrial conduction and electromechanical delay times compared to the control group. In addition, there was a positive correlation between intra-atrial delay time and P-wave dispersion in the GDM group.

Summary: This study developed a deep learning-based algorithm to identify atrial fibrillation using digital data from 12-lead electrocardiograms during normal sinus rhythm. The algorithm showed high accuracy in both internal and external validation datasets, providing new possibilities for early AF detection.

Summary: This study demonstrated that patients who achieved effective weight loss with bariatric surgery showed significant changes in ECG parameters related to atrial arrhythmia predictors, particularly in P wave dispersion, P wave peak time in lead D2, P wave peak time in lead V1, and terminal force in lead V1, within 6 months post-operation.

Summary: This study utilized extended ECG recordings to analyze atrial electrical activity characteristics in AF patients, revealing significant differences in P-wave and f-wave parameters between paroxysmal and persistent AF. Furthermore, correlations were found between echocardiographic parameters and P-wave and f-wave parameters, with extended ECG significantly improving AF-type classification performance.

Summary: This study assessed the specific contributions of atrial fibrillation-related atrial arrhythmia vs. associated ventricular arrhythmia to remodeling. The results showed that both atrial tachyarrhythmia and rapid ventricular response during AF produce distinct atrial remodelling, providing new insights into AF-related remodeling and ventricular rate-control considerations.

Summary: This study aimed to evaluate the association between electrocardiographic P wave indices and the severity of COVID-19 infection indicated as intensive care unit (ICU) admission. The results showed that P wave dispersion (Pdis) and P wave peak time (PWPT) were associated with ICU admission in newly diagnosed COVID-19 patients.

Summary: The authors use non-invasive atrial electromechanical assessment during atrial fibrillation to identify early remodeling changes associated with underlying myopathy, which decreases the probability of successful rhythm control. This study provides mechanistic insights into the electromechanical remodeling process associated with AF progression and demonstrates its prognostic value in the clinic.

Summary: This study aimed to explore the association between monocyte to HDL cholesterol ratio (MHR), lymphocyte to monocyte ratio (LMR), and neutrophil to lymphocyte ratio (NLR) with pulmonary arterial hypertension (PAH). The results showed that MHR and NLR were positively correlated with PAH, while LMR was negatively correlated with PAH, suggesting that these ratios may serve as significant predictors of PAH.
