Definitions
- ABSTRACT lmproved apparatus and method for temporary pacing comprising a catheter having a first electrode positioned for placement in the patient's heart and a second electrode positioned to be within the patient's body but sufficiently proximal that it is outside the patients heart, the second electrode having a surface area about an order of magnitude greater than the first, the electrodes being connected through respective leads within the catheter to a pacemaker (registered trademark, US. Patent Ofiice), with the first electrode connected as the cathode.
- a pacemaker registered trademark, US. Patent Ofiice
- Field of the Invention lies in the area of heart pacing apparatus and, more particularly, in the area of catheters used with external and implanted Pacemaker for temporary and permanent pacing in a clinical environment.
- the apparatus and method of this invention are particularly adapted for demand pacing.
- Temporary pacing of a patient in the post-operative period following cardiac surgery is an established and effective means of treating arrhythmias or increasing cardiac output. Additionally, temporary pacing is particularly important and widely used with respect to complete heart block, especially in patients undergoing acute myocardial infarction. Such temporary pacing has been a widely used clinical procedure in this country for many years, and the technique of inserting the catheter into the patient and pacing from an external source is a common technique of cardiology. A number of instrument manufacturers produce clinically acceptable catheters, and there are several models of Pacemakers well known to cardiologists and suitable for carrying out this technique,
- a first type is what is referred to as a unipolar catheter, having one lead extending substantially the length of the catheter and being electrically connected to an electrode which is positioned inside the patients heart for transmitting the desired electrical signal thereto.
- This cardiac electrode is connected through the catheter lead to a first terminal of a Pacemaker device which, in temporary pacing, is external to the patient, and which is designed to produce a desired periodic pacing signal.
- the second terminal of the external Pacemaker is connected to an electrode which is generally clamped to the patients skin around or near the point of entry of the catheter, which may be approximately at the large vein opposite the patients right elbow.
- Another suitable site such as in the femoral vein, may also be used for catheter insertion.
- Such electrode must be maintained in firm electrical contact with the patient, usually requiring some sort of electrically conductive paste be applied to the patients skin, as well as the use of additional means (such as suturing an electrode beneath the skin at the site of incision) for maintaining the electrode in firm position.
- additional means such as suturing an electrode beneath the skin at the site of incision
- the periodic output signals from the Pacemaker terminals produce biopotentials in the patients heart of a character so as to induce stimulation of the heart, i.e., so as to pace the heart.
- the second type of standard catheter in common use is what is referred to as a bipolar catheter.
- the advantage of the bipolar catheter over the unipolar form is the obvious one of eliminating the requirement of making an external attachment of one electrode to the patients skin. Using the bipolar catheter, the two leads of the catheter are simply connected directly to the external Pacemaker, or to whatever device is in clinical use.
- Pacemakers are designed to deliver 10-30 times as great a stimulus as is required for effective pacing at the time of electrode implantation.
- Pacemaker induced ventricular arrhythmias are possible, especially if the anode is positioned on or inside the ventricle.
- a catheter construction having a first (cardiac) electrode which is adapted to be positioned within the heart, and a second electrode positioned such that it will be within the patients body, but outside of and proximal to the heart and preferably of greater surface size than the cardiac elec trode.
- the cardiac electrode should be used as the cathode, and the proximal electrode as the anode.
- the second discovery which has led to my novel catheter apparatus design, and method for use of same, relates to the use of demand, or non-competitive Pacemakers.
- the demand Pacemaker the pacing signal is generated only upon demand, i.e., when the natural pacing signal of the patient is not sensed.
- demand Pacemakers are commonly used to avoid competition with sinus or ectopic beats. Competition between artificial and natural Pacemakers can result in an unacceptable increase in heart rate and may precipitate serious ventricular arrhythmias.
- bipolar electrodes can be positioned so as to detect a signal too small for demand sensing.
- a bipolar system adequate to detect sinus beats may not detect beats from a different origin such as ectopic ventricular beats.
- a unipolar electrogram could be obtained which was greater in magnitude and sufficient for proper demand function. Conversion of a bipolar electrode system to a unipolar system, with only one electrode in the heart, results in a simple and effective means of increasing the signal detected by the Pacemaker.
- catheter apparatus for pacing of a patients heart comprising a catheter having a first electrode, utilized as a cathode, positioned on the catheter such that it is within the patients heart when the catheter is fully positioned, and having a second electrode, utilized as an anode, and positioned proximal to the first electrode, having a surface area much larger than that of the cardiac electrode, and positioned so that it is external to the patient's heart during the pacing operation.
- Pacing is achieved by periodically delivering the pacing signal between a cathode positioned within the heart and an anode positioned outside of the heart.
- FIG. 1 is a diagrammatic sketch showing the placement of a catheter within a human body, and which indicates the critical areas of electrode placement according to this invention.
- FIG. 2 is a sketch showing the catheter apparatus of this invention in combination with an artificial Pacemaker.
- FIG. 2a is a detail sketch showing the connection of the anode of the catheter of this invention to one of the catheter electrical leads.
- FIG. 2b is a detail sketch showing the connection of the cathode of the catheter of this invention to the other of the catheter leads.
- FIG. 1 there is shown a diagrammatic sketch of a catheter 20 inserted into a human.
- the catheter is inserted at about position 21, into the right basilic vein.
- the tip of the catheter is manipulated through the superior vena cava, the right atrium, and into the right ventricle.
- the catheter may also be introduced through the external (or internal) jugular veins, subclavian veins, or femoral veins.
- a pair of electrical leads or one lead for a unipolar
- Pacemaker There are a number of commercially available Pacemakers which may be used in the practice of this invention. Such Pacemakers, and their manner of use, are well known to cardiologists.
- the two electrodes are both caused to reside in the right ventricle, as shown at 24, 25.
- a prior art unipolar catheter is utilized, there is only one heart electrode, such as 24, and a second electrode is placed upon the patient's skin near the point of entry at 21.
- the same catheter apparatus is utilized for demand pacing.
- Pacemaker 32 may be either a conventional Pacemaker type device or a demand type Pacemaker device.
- the catheter is an elongated and flexible instrument, constructed preferably of a plastic material such as nylon or Teflon, and of generally tubular form with substantially constant outer diameter fron end to end.
- the catheter of this invention has two electrical leads 34, 35, constructed of electrically conductive material, and embedded in the non-conductive plastic material.
- the larger of the two electrodes, 38 suitably a cylindrical ring, of conductive material, is positioned so that when the catheter is in place within the patient, it is outside of the patients heart.
- Electrode 40 which also is suitably a ring of conductive material around the outside of the catheter, and in electrical contact with the other of the two conducting leads, 35, as shown in FIG. 2b.
- Lead 35 in turn is connected to the negative terminal of Pacemaker 32, such that electrode is the cathodal electrode.
- This electrode is of relatively small surface area, and typically has a width of about 1-3 millimeters. For a catheter with outside circumference of approximately 6-10 millimeters, the total surface area would be approximately 6-24 square millimeters.
- the second electrode which is used as the anode, should be placed preferably at least 4 centimeters proximal to the heart (to the right atrium). This point is indicated in FIG. 1 by the dashed line indicated at 50.
- the anode should not extend beyond the region indicated approximately by the dashed line 52.
- the distance from the distal electrode (cathode) to dashed line 50 is about 23 centimeters, and the distance from dashed line 50 to dashed line 52 is about an additional 6 centimeters.
- the proximal electrode (anode) is suitably placed within this 6 centimeter distance (but need not be that long).
- the surface of the anode should be about 100-300 square millimeters.
- the proximalanode be much larger in surface area than the cathode, in order to distribute the anodal-induced, or positive-induced electric field intensity, so as not to stimulate surrounding structures.
- the distal electrode of the catheter is made the cathode by connecting it to the negative terminal of the Pacemaker 32, and the proximal electrode is made the anode by connecting it, through lead 35, to the positive terminal of Pacemaker 32.
- the apparatus of this invention provides that the anode is positioned safely outside of the patient's heart, and preferably at least 4 centimeters away from the patients heart, while the cathode is positioned within the patients right ventricle.
- the apparatus of this invention provides the advantages of the bipolar catheter, in that both electrodes are permanently affixed to the catheter, and there is no need for external placement of an electrode upon the patients skin.
- the positioning of the electrodes in accordance with this invention provides an effective unipolar type of pickup from the heart, so that when the catheter apparatus of this invention is used with a demand Pacemaker, the danger of detection of less than threshold signals is substantially reduced.
- the design criterion of making the anode at least 10 times as great as the cathode is also a critical limitation necessary to ensure against anodal stimulation, but use of an anode of lesser size would still be within the broad scope of this invention.
