Performing chest X-ray is an important annual investigation to check pacemaker lead integrity during follow-up of patients with pacemakers. Understanding lead design is vital to the correct interpretation of X-rays to prevent inappropriate interventions for patients as highlighted in this case.

A young man in his 30s presented to us with multiple episodes of syncope and exertional dyspnoea for the last 2 weeks. He was diagnosed with squamous cell carcinoma of the lower one-third of the oesophagus in 2021 for which he was treated with neoadjuvant chemoradiotherapy, followed by McKeown oesophagectomy. At 2-year follow-up, he had developed a soft tissue swelling in the scalp, which was diagnosed as a tumour recurrence and radiotherapy was initiated.

Background: Obstructive sleep apnoea (OSA) may lead to heart rhythm abnormalities including bradycardia. Our aim was to ascertain clinical and echocardiographic parameters in patients with OSA in whom severe bradycardia was detected in an outpatient setting, as well as to evaluate the efficacy of CPAP therapy on heart rate normalization at the early stages of treatment.
Methods: Fifteen patients mild, moderate or severe OSA and concomitant bradycardia were enrolled.

This case details the successful implantation of a leadless pacemaker following the extraction of transvenous leads in a 72-year-old female patient with a complex cardiovascular history. The patient had undergone a series of cardiac interventions, including a recent percutaneous tricuspid valve repair with a metal clip implant due to severe regurgitation. After presenting with an infection at the pacemaker site, methicillin-resistant Staphylococcus hominis was identified, necessitating the removal of the entire pacing system.

Objective: To compare the paced QRS duration on different sites in age-, gender-, and indication-matched patients implanted with Micra leadless pacemakers and conventional transvenous pacemakers (TV-PM).
Method: A total of 82 patients from Xinhua Hospital, Shanghai Jiaotong University, were enrolled, including two groups of 41 patients matched according to gender, age, and pacemaker indications, who underwent Micra and TV-PM implantations, respectively. The baseline data of the patients, the pacing site described using three- and nine-partition methods, and the paced QRS duration on 12-lead electrocardiogram were then analyzed.

Background: Our aim in this case was to remove the defective ventricular lead and the ruptured coronary sinus lead.
Methods: Entering through the right femoral vein and removing the coronary sinus lead with a pigtail catheter.
Results: In our attempt to extract the coronary sinus lead, it fractured.
