Programmed electrical stimulation--before when, how?

Application of qualitative research in management (why, when and how)

Application of qualitative research in management (why, when and how) Qualitative research has been increasingly used in all sciences. In this paper we will discuss about the applications of qualitative research methods in management sciences. The differences between quantitative and qualitative researches will be clarified and the statistical methods which are suitable for such researches will...

Monophasic action potential duration during programmed electrical stimulation.

UNLABELLED To examine changes in monophasic action potential duration (APD) with a pacing protocol similar to that used during electrophysiological testing, action potentials were recorded in vivo from the left ventricular apical endocardium of 12 normal mongrel dogs. The atrioventricular node was ablated and the dogs paced from the anterior right ventricle at a baseline cycle length of 1000 ms...

Risk Stratification in Brugada Syndrome: Role of Programmed Electrical Stimulation

Brugada syndrome (BS) is an arrhythmogenic disease characterized by a typical electrocardiographic finding (type 1 Brugada electrocardiogram [ECG]) and an increased risk for sudden cardiac death (SCD) due to polymorphic ventricular tachycardia or ventricular fibrillation (VF). Risk stratification remains a challenge, especially in cases without documented cardiac arrest or VF. The role of progr...

Factored Planning: How, When, and When Not

Automated domain factoring, and planning methods that utilize them, have long been of interest to planning researchers. Recent work in this area yielded new theoretical insight and algorithms, but left many questions open: How to decompose a domain into factors? How to work with these factors? And whether and when decomposition-based methods are useful? This paper provides theoretical analysis ...
