Current concepts for selecting the location, size and shape of defibrillation electrodes.
TL;DR: This article is concerned with the last three of tbese variables, which can be altered to attempt to lower tbe shock strength required for defibrillation, including those dealing with the shock waveform, including duration, polarity, and wavesbape.

The effect of vardenafil, a potent and highly selective phosphodiesterase-5 inhibitor for the treatment of erectile dysfunction, on the cardiovascular response to exercise in patients with coronary artery disease
Udho Thadani,William M. Smith,Stephen D. Nash,Neville Bittar,Stephen P. Glasser,Puneet Narayan,Richard A. Stein,Sharon Larkin,Arthur Mazzu,Robert Tota,Kenneth Pomerantz,Pavur Sundaresan +11 more
TL;DR: Vardenafil 10 mg did not impair the ability of patients with stable CAD to exercise at levels equivalent or greater than that attained during sexual intercourse, and safety was upheld.

TL;DR: 127° RF may be a better energy configuration for linear ablation than the other RF modalities tested by tissue temperature, lesion depth and uniformity, and RF power requirement.

A computerized method for the rapid display of ventricular activation during the intraoperative study of arrhythmias.
Raymond E. Ideker,William M. Smith,A G Wallace,J Kasell,Lura Harrison,G J Klein,Robert Kinicki,John J. Gallagher +7 more
TL;DR: A computerized method was developed to record potentials simultaneously from up to 27 electrodes and to display epicardial and transmural activation sequences rapidly, which can be determined if the arrhythmia can be induced three or more times.

Regional Capture of Fibrillating Ventricular Myocardium Evidence of an Excitable Gap
Bruce H. Kenknight,Philip V. Bayly,Ronald J. Gerstle,Dennis L. Rollins,Patrick D. Wolf,William M. Smith,Raymond E. Ideker +6 more
TL;DR: It is demonstrated that appropriately timed stimuli produce regional capture of fibrillating right ventricular myocardium in the pig and support the existence of an excitable gap during VF in this model.
