Supraventricular tachyarrhythmia (including atrial fibrillation), hypertension and tachycardia in the perioperative setting, and acute ischaemic heart disease are generally agreed to require rapid attention and treatment. Prolonged tachyarrhythmia or hypertension can result in significant morbidity, such as cerebrovascular events, myocardial infarction and other end-organ damage. This article reviews the clinical ...

Abrupt changes in heart rate, particularly short-long-short sequences in the ventricular cycle length (CL), might precede initiation of ventricular tachycardia/fibrillation (VT/VF). These changes may be facilitated or caused by pacing activity in patients with pacemakers or implantable-cardioverter defibrillators (ICDs). We describe a patient with two episodes of acquired VT precipitated ...

Until recently acute inflammatory peri-myocardial syndromes have been associated with global rather regional left ventricular (LV) dysfunction. Recent advances in cardiac imaging with echocardiographic techniques and magnetic resonance imaging (MRI) permit comprehensive evaluation of global and regional LV function. Our study was aimed to assess regional LV function in 100 ...

It is unclear whether intracoronary (IC) bolus administration of glycoprotein IIb/IIIa inhibitors (GPIs) during percutaneous coronary intervention (PCI) in patients with acute coronary syndromes is superior to intravenous (IV) administration. We conducted a meta-analysis of randomized controlled trials (RCTs) to compare the effects of IC and IV administrations of GPIs ...

Percutaneous coronary stenting is synonymous with dual antiplatelet therapy, ranging from four weeks to lifelong. However, even short-term (four weeks) therapy with aspirin and thienopyridines is occasionally contraindicated. No study has ever appraised very short-term dual antiplatelet therapy after stenting. We thus aimed to exploit the pro-healing features of the ...

Despite observations suggesting a benefit for late opening of totally occluded infarct-related arteries after myocardial infarction, the Occluded Artery Trial (OAT) demonstrated no reduction in the composite of death, reinfarction, and class IV heart failure over a 2.9-year mean follow-up. Follow-up was extended to determine whether late trends would favor ...

Atrioventricular conduction prolongation (AVCP) in cardiac pacing is measurable and results primarily from delayed atrial conduction. Noninvasive methods for measuring atrial conduction are lacking. Accordingly, AVCP was used to estimate atrial conduction and investigate its role on the paced atrioventricular delay (pAVD) during biventricular pacing (BiVP) optimization. Retrospective analysis of ...

Randomized controlled trials (RCTs) are the centerpiece of evidence-based medicine. However, because of the limited follow-up, additional evidence on the long-term consequences of the outcomes used in trials is commonly required for clinical and policy decision making. This article provides insights into the importance and challenges of using such evidence ...

There has been growing evidence that the Purkinje network plays a pivotal role in both the initiation and perpetuation of ventricular fibrillation (VF). A triggering ventricular premature beat (VPB) with a short-coupling interval could arise from either the right or left Purkinje system in patients with polymorphic ventricular tachycardia (VT) ...
