Structured PICO
Does electrode design affect the efficiency of radiofrequency energy delivery and lesion characteristics in dog ventricular muscle in vitro?
P
Population
Dog ventricular muscle in vitro
I
Intervention
Four types of electrodes for radiofrequency energy delivery (imbeddable needle electrode, standard electrode catheter, masked electrode catheter, flat thermally insulated electrode)
C
Comparator
Comparison among the four electrode types
O
Outcome
Efficiency of delivery of radiofrequency energy (lesion volume/energy-delivered ratio) and characteristics of the lesions producedsurrogate
Electrode design significantly impacts the efficiency of radiofrequency energy delivery for lesion production in cardiac tissue, with imbeddable and masked designs showing higher efficiency than standard catheters.
