Controlled Clinical Trial
Non-invasive cardiac output measurements based on bioreactance for optimization of atrio- and interventricular delays.
Non-invasive cardiac output monitoring (NICOM) based on bio-reactance offers a portable method to assess ventricular function. Optimization of cardiac resynchronization therapy (CRT) by echocardiography is labour-intensive. We compared the ability of NICOM and echocardiography to facilitate optimum CRT device programming. ⋯ Non-invasive cardiac output monitoring is a simple, reliable, and portable alternative to echocardiography to program CRT devices.

Case Reports
A life-threatening arrhythmia induced by inappropriate activation of an implantable cardioverter defibrillator.
We describe an unusual case of near fatal inappropriate implantable cardioverter defibrillator therapies due to atrial oversensing by a newly implanted ventricular lead. Chest X-ray revealed dislodgement of the active fixation lead to the tricuspid annulus area explaining the atrial oversensing and intermittent ventricular therapies.

Aim of this study was to investigate the diagnostic accuracy of the conventional electrocardiogram (ECG) algorithm [ST-segment elevation (STE) in lead III exceeding that in lead II combined with ST-segment depression in lead I or aVL] for identification of the infarct-related artery (IRA) in a large cohort of patients undergoing primary percutaneous coronary intervention (PCI) for inferior wall STE myocardial infarction (STEMI). ⋯ The conventional ECG algorithm showed a low sensitivity for the non-invasive diagnosis of RCA occlusion in an all-comer, inferior STEMI cohort undergoing primary PCI. Sensitivity was only sufficient in patients with extensive ST-segment deviation.
