16. A method for pacing a heart of a patient, the method comprising:
(a) introducing a sheath into the right atrium of the heart of the patient;
(b) advancing a distal end of a pacing electrode through a lumen of the sheath to a target location, the distal end of the pacing electrode comprising:
(i) a linear segment extending at a distal tip of the pacing electrode, wherein the linear segment is configured to pierce cardiac tissue to a first depth of the cardiac tissue for testing the placement of the pacing electrode at the target location, and
(ii) a helical segment at a proximal end of the linear needle, wherein the helical segment is configured to screw into the target location, thereby advancing the linear needle to a second depth of the cardiac tissue and anchoring the pacing electrode to the target location;
(c) (i) coupling the linear segment of the pacing electrode to a cardiac tissue at the target location, (ii) activating the pacing electrode to generate a first diagnostic result, (iii) acquiring the first diagnostic result, and (iv) determining whether the pacing electrode at the target location is efficacious based on the first diagnostic result;
(d) coupling the helical feature of the pacing electrode to the cardiac tissue at the target location if the pacing electrode at the target location is determined to be efficacious based on the first diagnostic result; and
(e) electrically pacing the target location using the pacing electrode.
