SYSTEM AND METHOD FOR DETERMINING ELECTRODE-TISSUE CONTACT BASED ON AMPLITUDE MODULATION OF SENSED SIGNAL |
摘要 |
Methods and systems for monitoring contact between a medical probe and tissue are provided. A medical probe is introduced into a patient adjacent the tissue. An electrical parameter, e.g., electrical admittance, is measuring between a first electrode located on the medical probe and a second electrode remote from the first electrode. The electrical parameter is amplitude modulated in response to a physiological cycle of the patient. Contact between the medical probe and the tissue is detected based on the amplitude modulation of the measured electrical parameter. |
