“…High-voltage low-charge 2 0 A, 30 p pulses resulted in significantly more tissue injury than high-charge low-voltage 2 A, 30 p pulses at I , 10, and 30 days. Also note that lesion volume is nearly constant over time for high-charge low-voltage pulses, whereas lesion volume decreases markedly over the course of 30 days for high-voltage low-charge pulses.…”

Summary:The development of catheter ablation techniques for therapy of cardiac arrhythmias continues to evolve. Although many patients have benefited from catheter ablation procedures. failure to ablate the anhythmogcnic substrate and complications from the pulse used in these procedures remain too frequent occurrences. The pu'pose of this review is to focus on these problems of inefficacy and safety with attention directed to the role various direct current and radiofrequency pulses have had in the genesis of these difficulties.

“…They also carried the potential for significant complications, such as cardiac tamponade and the early or late occurrence of sudden death. 25,26 Technological advancements in the late 1980s led to the ability to apply continuous-wave unmodulated radiofrequency energy through catheters to heat myocardium at the catheter-tissue interface, creating ablative lesions. 27 Although initial success rates were modest, 27,28 further development in technology resulted in a technique that has replaced DC energy delivery.…”

“…In the first two patients, shocks to zone 3 were delivered between the two electrodes of the coronary sinus catheter outside the coronary sinus ostium (cathode) and the skin electrode (anode). Patients received [1][2][3][4][5][6][7] shocks of 100-300 J to one (n=2), two (n=3), or three (n=4) areas (Table 2). Procedure …”

Our purpose was to describe a technique of atrioventricular (AV) node modification for patients with drug refractory AV nodal reentrant tachycardia (AVNRT). Nine patients (mean age, 45±20; range, 14-82) with recurrent drug refractory AVNRT (n=8) or sudden cardiac death thought to be precipitated by AVNRT (n = 1) underwent a percutaneous catheter procedure to modify AV nodal function. The area between the electrode recording the maximal His-bundle electrogram and the ostium of the coronary sinus was divided into three zones. Perinodal direct current shocks of 100-300 J were delivered to one (n=2), two (n=3), or three (n=4) zones without complications. The procedure endpoints were modification of AV conduction (either first degree AV block or complete retrograde ventriculo-atrial [VA] block) and failure to induce AVNRT before or after isoproterenol and/or atropine administration. Six of nine patients (67%) have had no inducible or spontaneous AVNRT over a mean follow-up of 12.3 ±4.1 months (range, 4.5-17). One of the six underwent repeat, successful modification, because AVNRT was inducible at restudy 2 days after the initial procedure. AVNRT recurred in three patients (33%), one early (3 days) and two late (3-4 months). Two of these patients underwent complete ablation of the AV junction and permanent pacemaker placement, whereas one is controlled with drug therapy. Therefore, AV nodal modification resulted in tachycardia control without antiarrhythmic drugs in six of nine (67%) and obviated the need for complete AV junctional ablation in seven of nine patients (78%
