Termination of idiopathic sustained monomorphic ventricular tachycardia by intravenous adenosine in a pregnant womanEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
A 34-year-old pregnant woman presented to the emergency department with the complaints of palpitations at 32 weeks gestation. The diagnosis of right ventricular outflow tract ventricular tachycardia (VT) was made. Intravenous 5 mg of metoprolol and 25 mg of diltiazem did not terminate the VT. Ten milligrams of adenosine were administered. Within 10 s of adenosine administration, sustained VT converted to repetitive monomorphic VT and within 30 s to normal sinus rhythm. The mother and the foetus tolerated the medications well. Non-stress test for the assessment of the foetal well-being was normal. (Source: Europace)

Ventricular fibrillation associated with coronary vasospasm developed 8 h after successful radiofrequency (RF) ablation of the right accessory pathway in an 81-year-old male. A segment of the coronary vasospasm was located close to the accessory pathway, where seven RF ablations had been applied. Although rare, physicians should carefully consider the risk of such events when an RF current is applied near a coronary artery. (Source: Europace)

Sudden cardiac death stratification in asymptomatic ventricular preexcitationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The second survey deals with risk stratification in subjects, either adults or children, with ventricular preexcitation and no symptoms in their history. Current European electrophysiological practice is still variable among different centres. Although invasive stratification is still part of the practical management of asymptomatic subjects, a not negligible proportion of physicians do not completely rely on cut off values provided in the literature, proceding to ablation irrespective of the stratification process. These concerns are mainly due to the perception of lack of strong evidence that, according to the majority o...

Conclusion Underlying aetiology does not affect the quantity and distribution of coronary veins available for LV lead placement.

Given these limitations, in many patients, prospective targeting of LV lead placement may require a direct surgical approach. (Source: Europace)

Electrophysiologically demonstrated complete conduction block at the level of the veno-atrial junction is preferable as the endpoint of pulmonary vein (PV) ablation rather than circumferential periostial radiofrequency delivery. Knowledge of the individual anatomy of the PVs and the left atrium (LA), appropriate positioning of circular mapping catheters, and the electrophysiology of PV activation in addition to effective ablation tools is necessary to achieve this endpoint. Additional unnecessary ablation and possibly complications can be avoided by the recognition of non-PV myocardial contributions to PV electrograms. The...

Undersensing of ventricular fibrillation due to interference between a pacemaker and defibrillator in the same patientEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Sensing in pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) is crucial to normal device behaviour. Since both devices treat different arrhythmias, the technical approach to signal detection is also completely different. A PM has a fixed threshold of sensing, above which events are sensed and therapy of the device withheld. On the other hand, the defibrillator has a variable threshold of sensing to detect tachyarrhythmias, with sometimes very small and changing electrogram amplitudes. In this case report, we describe interference between a PM and an ICD caused by these differences in the detection of card...
