    • A unitary intravascular defibrillating catheter includes distal and proximal spring electrodes, displaced to such distance from one another that defibrillating shock is effected through a field including the interventricular septum and left ventricular free wall. In one embodiment of this catheter, the proximal electrode is placed in the region of the subclavian vein. Alternatively, it may be placed in the region of the third through seventh intercostal space. A unitary catheter is also described which includes an intermediate electrode, placed between distal and proximal electrodes. Selection of placement of electrodes either in the superior vena cava or in the region of the subclavian vein is medically indicated by physiological conditions of the individual patient. The cardioversion system further includes a unipolar or bipolar sensing circuit with at least one sensing electrode, and a cardioversion/defibrillation circuit with either two or three spaced apart spring electrodes. The sensing electrodes are spaced apart from one another, but they are kept sufficiently close to one another for isolated, localized R-wave sensing. The sensing electrodes further are positioned remotely of the cardioversion/defibrillation electrodes, to avoid post-shock abnormalities which otherwise would interfere with a timely R-wave sensing, and to substantially prevent the discharge of an unnecessary cardioversion pulse after return of the heart to normal cardiac rhythm.

    • A cardioversion system includes a bipolar sensing circuit with two sensing electrodes, and a cardioversion circuit with two spaced apart spring electrodes. The sensing electrodes are spaced apart from one another but kept sufficiently close to one another for isolated, localized R-wave sensing. The sensing electrodes further are positioned remotely of the cardioversion electrodes, to avoid post-shock abnormalities which otherwise would interfere with a timely R-wave sensing, to substantially prevent the discharge of an unnecessary cardioversion pulse after return of the heart to normal cardiac rhythm. One preferred version of the system is a unitary catheter including a distal tip electrode and ring electrode as the sensing electrodes, and to substantially larger, more proximal spring electrodes for defibrillation. Alternatively, the defibrillation electrodes and the sensing electrodes can be provided on two separate catheters. Yet another alternative involves providing one or more patch electrodes as defibrillation electrodes.
    • 复律系统包括具有两个感测电极的双极感测电路和具有两个间隔开的弹簧电极的心电复律电路。 感测电极彼此间隔开,但彼此保持足够接近以进行隔离的局部R波感测。 检测电极进一步位于心复律电极的远端,以避免后期的异常,否则会干扰及时的R波检测,从而基本上防止在心脏恢复正常的心脏节律之后放出不必要的心脏复律脉冲。 系统的一个优选方案是整体导管,其包括作为感测电极的远侧末端电极和环形电极,以及用于除颤的基本上较大的更近的弹簧电极。 或者,除颤电极和感测电极可以设置在两个分开的导管上。 另一替代方案涉及提供一个或多个贴片电极作为除颤电极。

    • An apparatus for stimulating and sensing evoked response to stimulus in the heart. First and second electrodes are in electrical contact with the heart, a third indifferent electrode is also in electrical contact with the heart. A pacemaker provides stimulus signals through the electrodes in the stimulating mode of operation. The first and second electrodes are switched through switching apparatus wherein in the first mode the first and second electrodes are maintained at equal electrical potentials, and in a second, sensing mode, the switch operates between the first and second electrodes so as to allow the first and second electrodes to act as bipolar sensing leads. Evoked response is sensed by a differential amplifier having a first differential input connected to the first electrode and a second differential input connected to the second electrode. The differential amplifier provides a differential signal which is proportional to the evoked cardiac response.

    • Disclosed are an electrode configuration and a method for its use with an automatic implantable cardioverter/defibrillator. The electrode configuration includes a catheter electrode intravenously positioned within the heart of a patient wherein one electrode, defined by the catheter, is within the right ventricle and a second electrode, also defined by the catheter and spaced from the first electrode, is within the superior vena cava region. A third electrode, in the form of a flexible, substantially planar patch, is subcutaneously positioned outside the thoracic cavity in the region of the left ventricle. At the time of electrical discharge, or permanently, the first and second electrodes of the catheter are connected together. The electrode arrangement can be implanted without opening of the thoracic cavity by intravenously placing the catheter electrode within the heart of a patient and subcutaneously implanting the patch electrode between the skin and the thoracic cavity. The automatic implantable cardioverter/defibrillator senses life-threatening arrhythmic conditions of the heart and issues at least one cardioverting or defibrillating pulse that is applied between the electrode positioned in the region of the left ventricle and the commonly connected catheter electrodes positioned, respectively, in the right ventricle and within the superior vena cava region. The catheter also includes a pacing tip.
