- Prior methods for treating a patient's arrhythmia include the
- antiarrhythmic drugs such as sodium and calcium channel blockers or drugs which reduce the Beta-adrenergic activity.
- Other methods include the surgically sectioning the origin of the signals causing the arrhythmia or the conducting pathway for such signals. More frequently,

- the catheter may range from about 0.03 to about 0.1 inch (0.76-2.54 mm) but preferably is about 0.03 to about 0.05 inch (0.076-1 .27 mm), particularly 0.035 to about 0.040 inch (0.89-1.02 mm).
- the proximal portion 96 of the catheter 91 makes up about 70 to about 95% of the total length of the catheter with the intermediate portion 97 and the distal portion 98 which has the sensing electrodes 92 and 93 being the remainder.
- the catheter 91 has decreasing stiffness from the proximal portion 96 to the intermediate portion 97 and the distal portion 98 to facilitate the advancement of the catheter 91 within the patient's vasculature.
- the exterior surface of the catheter 91 and the surface defining inner lumen 95 may be formed of lubricous materials or hydrophilic materials which become lubricous when contacting aqueous based fluids. Polysulfones and polyfluoroalkanes are
- suitable lubricous polymers and polyvinylpyrrolidone, polyethylene oxide and acrylate-based polymers of examples of suitable hydrophilic polymers.
- the proximal end of the catheter 91 may be provided with a
- multiple arm adapter 99 as shown in Fig. 13 with one arm 100 which is configured to receive a syringe for delivering fluid into the inner lumen 97
- central arm 106 facilitates entry of a guidewire (not shown) into the inner lumen 97.
- the catheter 91 may be advanced into position within the patient's vascular system, i.e. either the coronary arteries or the cardiac veins, over a guidewire which may or may not have electrodes in
- vasculature does not have sensing electrodes on its distal extremity, it may be withdrawn when the catheter is in its desired position and a
- guidewire such as shown in Fig. 4 may be advanced through the inner lumen 95 of the catheter 91 and out the port 103 in the distal end of the

- each electrode pair 1 10 and 1 1 1 is shown adjacent thereto, and as indicated, all of the responses are essentially identical, except for the time-of-occurrence, because the wave front reaches all of the electrodes at the same angle.
- Fig. 16 represents an idealized response from a plurality of electrode pairs 120 and 121 on two separate intravascular devices (not shown) disposed in different generally parallel coronary blood vessels, as in Fig. 16, but the wave front 122 originates from a site between and in close proximity to the catheters.
- the idealized wave front 121 is circular and the size and polarity of the responses 123 and 124 to the expanding wave front varies according to the angle of incidence between the wave front and the electrode pair.
- An arrhythmogenic site would create a less than ideal wave front which can be readily detected by the plurality of electrodes 120 and 121.
- the time of occurrence and directional information obtained from the response from the wave front may be used to determine the origin of the ectopic beat.
- a guidewire was constructed using a woven tubular braid of
- the guidewire assembly was 0.018 inch (0.46 mm) in diameter at the distal end, 0.026 inch (0.66 mm) in diameter at the midsection, and 0.032 inch (0.81 mm) at the more proximal end.
- the guidewire was introduced into the coronary artery of a live dog using a 7 French coronary guide catheter.
- Fig. 17 is an electrocardiogram produced using the guidewire of the invention which depicts two pulses from that animal test in bipolar mode.
