Background: The incidence of tuberculous pericarditis has increased in Africa as a result of the human immunodeficiency virus (HIV) epidemic. However, the effect of HIV co-infection on clinical

In this study, a higher LVEF was associated with a greater risk of lead fracture in patients with Sprint Fidelis 6949 ICD leads. Radiographic features did not predict subsequent risk of lead fracture in our population. (PACE 2010; 437-443).

Our study identified significant underutilization of bridging, particularly in the postoperative period, in patients at "moderate/high risk" of thromboembolism. Conversely, bridging was overused in "low risk" patients and associated with bleeding complications. Physicians should be urged to follow current expert guidelines in regard to bridging anticoagulation for cardiac rhythm device surgery. (PACE 2012;35:1480-1486).

Patients present to the emergency department with either an ongoing tachycardia or a history suspicious of a tachycardia. Either way, the tachycardia needs to be documented, preferably on a 12-lead electrocardiogram (ECG) for diagnosis and management. If a tachycardia is not documented, a careful history of the palpitations should be taken to see if further monitoring and investigations are required. If a tachycardia is confirmed on an ECG, the clinician needs to classify it according to two variables: (i) regularity of the rhythm; and (ii) QRS width. This will allow a differential diagnosis to be made.
