Bradyarrhythmias can present as an incidental electrocardiographic (ECG) finding or a life-threatening condition requiring immediate intervention. They are caused by sinus node disease or atrioventricular block. This review covers pathophysiology, stabilization and assessment, diagnosis and treatment options, and disposition and outcomes for patients with bradycardia. Figures in the review demonstrate characteristic ECG tracings. Tables list classifications of sinus node dysfunction as well as of sinoatrial and atrioventricular blocks, presenting symptoms, important information to elicit on history taking, various causes of bradycardia, and specific interventions for toxicologic etiologies. Key words: atrioventricular block, atropine, bradyarrhythmia, bradycardia, first-degree atrioventricular block, second-degree atrioventricular block, sinoatrial block, sinus bradycardia, sinus node disease, tachycardia-bradycardia syndrome, third-degree atrioventricular block This review contains 9 highly rendered figures, 7 tables, and 92 references.

Anomalous Pulmonary Venous Connection

Background: Surgical repair of partial anomalous pulmonary venous connection (PAPVC) may disturb the electrical conduction in the atria. This study documents long-term outcomes, including the late occurrence of atrial tachyarrhythmia and bradyarrhythmia. Methods: This retrospective study covers all PAPVC operations at Aarhus University Hospital between 1970 and 2010. Outcome measures were arrhythmias, sinus node disease, pacemaker implantation, pathway stenosis (pulmonary vein(s), intra-atrial pathway, and/or superior vena cava), and mortality. Data were collected from databases, surgical protocols, and hospital records until May 2018. Results: A total of 83 patients were included with a postoperative follow-up period up to 46 years. Average age at follow-up was 43 ± 21 years. During follow-up, new-onset atrial fibrillation or atrial flutter appeared in four patients (5%). Sinus node disease was present in nine patients (11%). A permanent pacemaker was implanted in seven patients (8%) at an average of 12.7 years after surgery. Pulmonary venous and/or superior vena cava obstruction was seen in five patients (6%). Stenosis was most prevalent in the two-patch technique, and arrhythmia was most prevalent in the single-patch technique. Sixty-seven (81%) of 83 patients had neither bradyarrhythmias nor tachyarrhythmias or pacemaker need. Conclusions: This study contributes important long-term data concerning the course of patients who have undergone repair of PAPVC. It confirms that PAPVC can be operated with low postoperative morbidity. However, late-onset stenosis, bradyarrhythmias and tachyarrhythmias, and need for pacemaker call for continued follow-up.
