Primary prevention (PP) implantable cardioverter defibrillator (ICD) implant rates in the UK are below national targets and barriers to this are not well known. This study was designed to identify the stages along the referral pathway from general to specialist care that eligible patients reach and what proportion eventually receive an ICD. ⋯ Failure to refer from the general physician to cardiology and from the cardiologist to EP is the principle reason for low PP ICD implant rates among eligible patients in the UK.

Comparative Study
New electrocardiographic criteria to differentiate the Type-2 Brugada pattern from electrocardiogram of healthy athletes with r'-wave in leads V1/V2.
Diagnosis of Type-2 Brugada pattern remains challenging and it could be confused with other electrocardiogram (ECG) patterns presenting an r'-wave in leads V1-V2 like in healthy athletes. This could impact their ability to perform competitive sports. The aim of the study was to evaluate, as a proof of concept, the new ECG criteria to differentiate the Type-2 Brugada pattern from the ECG pattern of healthy athletes depicting an r'-wave in leads V1-V2. ⋯ The three new ECG criteria were accurate to distinguish the Type-2 Brugada pattern from the ECG pattern with an r'-wave in healthy athletes. The duration of the base of the triangle at 0.5 mV from the high take-off is the easiest to measure and may be used in clinical practice.

Previous studies have suggested a lower risk of atrial fibrillation (AF) with higher intakes of fish and marine n-3 polyunsaturated fatty acids (PUFAs), but the results have been inconsistent. The aim was to investigate the association between consumption of marine n-3 PUFA and development of AF. ⋯ We found a U-shaped association between consumption of marine n-3 PUFA and risk of incident AF, with the lowest risk close to the median intake of total marine n-3 PUFA (0.63 g/day).

To describe obstetric/neonatal and cardiac outcomes for a cohort of women carrying implantable cardioverter-defibrillators (ICDs) during pregnancy. ⋯ Pregnancy had no effect on ICD operation and no evidence was found to link ICD carriage with adverse pregnancy outcomes, although one miscarriage may have been induced by ICD shock therapy. A worsening of cardiac condition occurs in specific cardiac diseases and β-blocker therapy should be continued for all women carrying ICDs in pregnancy as the benefits outweigh the risks of taking this medication.
