Comparison of the temperature profile and pathological effect at unipolar, bipolar and phased radiofrequency current configurations
Autor: X, Zheng, G P, Walcott, D L, Rollins, J A, Hall, W M, Smith, G N, Kay, R E, Ideker
Publikováno v: Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing. 5(4)
With a multi-electrode catheter, phased radiofrequency (RF) delivers current between each electrode and a backplate as well as between adjacent electrodes. This study compared the tissue heating and lesion dimensions created by phased and standard RF

Novel methods to evaluate controlled reperfusion techniques in cardiac surgery
Autor: J L, Skinner, S B, Digerness, R D, Spruell, J M, Rogers, C R, Katholi, G P, Walcott, R E, Ideker, W L, Holman
Publikováno v: International journal of surgical investigation. 1(5)
This manuscript describes two novel techniques that may be useful for comparing methods to reperfuse the heart during cardiac operations. These techniques are based on measurements of intra-myocyte ion content and the analysis of reperfusion arrhythm

Effect of altering the left ventricular pressure on epicardial activation time in dogs with and without pacing-induced heart failure
Autor: P C, Fotuhi, N, Chattipakorn, D L, Rollins, J L, Bicknell, C M, Sreenan, C R, Killingsworth, G P, Walcott, R E, Ideker
Publikováno v: Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing. 4(4)
The influence of an increased left ventricular end-diastolic pressure (LVEDP) on the development of lethal arrhythmias in chronic heart failure is unclear. We investigated the effect of chronic and acute LVEDP increase on the epicardial activation ti

Electrode impedance: an indicator of electrode-tissue contact and lesion dimensions during linear ablation
Autor: X, Zheng, G P, Walcott, J A, Hall, D L, Rollins, W M, Smith, G N, Kay, R E, Ideker
Publikováno v: Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing. 4(4)
Pre-ablation impedance was evaluated for its ability to detect electrode-tissue contact and allow creation of long uniform linear lesions with a multi-electrode ablation catheter. The study consisted of 2 parts, both of which used the in vivopig thig

Defibrillation efficacy with endocardial electrodes is influenced by reductions in cardiac preload
Autor: J S, Strobel, G N, Kay, G P, Walcott, W M, Smith, R E, Ideker
Publikováno v: Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing. 1(2)
Little is known about the effects of cardiac preload and cardiac geometry on defibrillation efficacy with endocardial electrodes. We studied nine pigs implanted with an endocardial lead system in the normal and reduced preload state. In the reduced p

Mechanisms of defibrillation. Critical points and the upper limit of vulnerability
Autor: G P, Walcott, K T, Walcott, R E, Ideker
Publikováno v: Journal of electrocardiology.
The upper limit of vulnerability hypothesis for defibrillation states that a successful defibrillation shock must both stop the fibrillation wave fronts on the heart at the time that the shock is delivered and not start new wave fronts that will lead
