Abstract: Electrode structures (20) are formed from flexible, porous, or woven materials. One such structure is made by forming first and second body sections (225), each including a peripheral edge. The first and second body sections (225) are joined together about their peripheral edges with a seam (224), thereby forming a composite structure. Another one of such structures is made by forming a body having a three-dimensional shape and opposite open ends, and at least partially closing at least one of the opposite ends by forming a seam. Another one of such structures is formed from a sheet of material having peripheral edges. The sheet is placed on the distal end of a fixture, while the peripheral edges of the sheet are gathered about the proximal end of a fixture, thereby imparting to the sheet a desired shape. At least one pleat is formed to secure the gathered peripheral edges together. The seams or pleats are formed by thermal bonding, or ultrasonic welding, or laser welding, or adhesive bonding, or sewing.

Abstract: A method for treating ventricular tachycardia comprises inserting an electrode catheter into the ventricule. The ventricular wall of the heart is contacted with an ablation electrode (20) at a site where an aberrant electrical pathway is located. Radiofrequency is delivered through the ablation electrode (20) to the tissue for a time sufficient to confirm the site of the aberrant electrical pathway and to preheat the tissue. Short high voltage electrical pulses are then delivered to the tissue through the same electrode (20) to thereby form a non-conductive lesion.

Abstract: This invention is systems and methods to examine heart tissue morphology using three or more spaced apart electrodes (38), at least two of which are located within the heart in contact with endocardial tissue. The systems and methods transmit electrical currents (64) through a region of heart tissue lying between selected pairs of the electrodes, at least one of the electrodes in each pair being located within the heart. The systems and methods derive the electrical characteristic of tissue lying between the electrode pairs based, at least in part, upon sensing tissue impedances. The systems and methods (206) also sense the timing of local depolarization events in the tissue in which impedance is sensed, and derive therefrom the propagation velocities of the sensed depolarization events.

Abstract: A method for express analysis of heart-beat rhythm in which the signal is picked up from a living being by means of electrodes (3, 4, 5) which in a preferred embodiment have a form of holding clips and can be connected to the patient's fingers or toes. The electrocardiogram (ECG) signal is converted to a digital signal which is then processed by a microprocessor and displayed in real time on a liquid crystal display (LCD) (2) placed on one of the sides of a casing (1). The ECG signal is stored and when a corresponding key is pushed on a keyboard (6) all the accumulated PQRST-complexes are shown on the LCD (2) page by page. The duration of R-R intervals is measured with assigned precision which corresponds to the characteristic scale of the heart-beat rhythm variations in the stationary phase. The results of these measurements are displayed in real time on the LCD (2) in the form of rhythmograms (RG) and histograms (HG) so that both RG and HG steps correspond to the said characteristic scale.
