The Anatolian Journal of Cardiology's "Focus on Arrhythmias" discusses various studies from China and India on conditions such as High Altitude Pulmonary Hypertension, constrictive pericarditis, and atrial fibrillation. The research highlights the role of immune responses, genetic predispositions, and diagnostic accuracy in identifying and treating these cardiac rhythm disorders. The journal also emphasizes the importance of transcriptomic profiles in understanding the molecular mechanisms underlying atrial fibrillation for targeted therapies. Additionally, the study suggests reevaluating definitions of blanking periods to improve outcomes for patients undergoing catheter ablation procedures.
