Why the study?
How do intracardiac catheter fibrillation thresholds vary with the duration of 60 Hz current and electrode area?
How do intracardiac catheter fibrillation thresholds vary with the duration of 60 Hz current and electrode area?
Intracardiac fibrillation thresholds are exponentially related to the duration of 60 Hz current flow and are influenced by catheter electrode area.
No takes yet. Share an insight, caveat, or question.
May refine 60 Hz leakage limits during catheterization; leaves open human translation from animal thresholds.
