Three-dimensional finite element analysis of current density and temperature distributions during radio-frequency ablation
This study analyzed the influence of electrode geometry, tissue-electrode angle, and blood flow on current density and temperature distribution, lesion size, and power requirements during radio-frequency ablation. Expand

Improved myocardial preservation at 4 degrees C.
We tested the ability of various cardiac preservation techniques to preserve left ventricular function of isolated canine hearts using preservation temperatures of 4 degrees or 15 degrees C. The fourExpand

Diagnosis and management of the hypothyroid patient with chest pain.
A retrospective analysis of 38 patients undergoing cardiac catheterization with the diagnoses of hypothyroidism and chest pain revealed 23 to be euthyroid while receiving replacement therapy and 15Expand

A Closed‐Chest Pig Model of Sustained Ventricular Tachycardia
The goal of this study was to develop and explore a closed‐chest animal model of sustained VT. Seven of 11 domestic pigs had successful induction of myocardiai infarction by injection of agarose gelExpand

Transcutaneous multielectrode basket catheter for endocardial mapping and ablation of ventricular tachycardia in the pig.
BACKGROUND Endocardial mapping using standard electrode catheters is often technically limited in ventricular tachycardia and constitutes a major obstacle to successful ablation. We wished to examineExpand

Is the Second Phase of a Biphasic Defibrillation Waveform the Defihrillating Phase?
Why some biphasic waveforms defibrillate with lower energies than monophasic waveforms of similar duration is unknown. One hypothesis is that the first phase of a hiphasic waveform acts as aExpand

Arterial blood-flow waveform measurement in intact animals: new digital radiographic technique.
With a new radiographic method to determine the pulsatile flow pattern in an imaged artery, flow velocity is determined by tracking the movement of contrast material along the artery over time. FlowExpand

Radiofrequency multielectrode catheter ablation in the atrium.
We developed a temperature-controlled radiofrequency (RF) system which can ablate by delivering energy to up to six 12.5 mm long coil electrodes simultaneously. Temperature feedback was obtained fromExpand
