Right ventricular (RV) pacing, particularly from the RV apex, causes bilateral ventricular dyssynchrony, reducing systolic and diastolic function, by delayed activation of the lateral left ventricle, resulting in a wide QRS with a left bundle branch block (LBBB) morphology. Alternative pacing strategies, such as His-bundle pacing and LBB area pacing, tend to be more physiological, avoiding this problem. The feasibility of attaining a narrow paced QRS from the RV septum has not been methodically examined.

Background: Persistent left superior vena cava (PLSVC) is a rare congenital venous anomaly. Permanent pacemaker implantation (PPI) in patients with PLSVC presents challenges in placing both the right ventricular and atrial leads. The article describes a technique for dual-chamber PPI using standard leads in a PLSVC patient with chronic kidney disease on maintenance hemodialysis.

Background: This manuscript describes the first known cases of sick sinus syndrome (SSS) associated with the use of anlotinib in non-small cell lung cancer patients, highlighting the need for increased vigilance and cardiac monitoring.
Case Summary: Two patients with non-small cell lung cancer developed SSS after 15 months and 5 months of anlotinib treatment, respectively, presenting with syncope and palpitations. Electrocardiogram confirmed SSS, and different treatment approaches were taken for each patient.
