Abstract
A method and medical system to take electrical readings includes an electrocardiogram (ECG) monitor, an electrode coupled to the monitor via a first lead and a needle such as an injection needle. The needle has a proximal end coupled to the monitor, where the monitor is able to measure an electrical pattern between the electrode and a distal end of the needle. In one example, the medical system is used to detect the contact, penetration, health and perforation of tissue at a target site.

26. A method comprising:
-
receiving a reference signal from a skin electrode attached to a patient;
receiving a measurement signal from a needle having a distal end that is being guided toward heart wall tissue of the patient; and
generating a tracing that indicates whether a catheter tip associated with the distal end of the needle has contacted the heart wall tissue based on the reference signal and the measurement signal. - View Dependent Claims (27, 28, 29, 30)
