Systems and methods for cardiac pacing during a procedure are disclosed and may include an external pulse generator (EPG) for connecting to a lead. A remote-control module (RCM) wirelessly connected to the EPG may include user inputs to control the EPG. A central processing unit (CPU) with a memory unit for storing code and a processor for executing the code may be included where the CPU is connected to the EPG and RCM. The code may control the EPG in response to user input from the RCM. The CPU may be disposed in the EPG or the RCM, or an interface module (IM) configured to communicate between an otherwise conventional EPG and the RCM. The executable code may perform a continuity test (CT) routine, a capture check (CC) routine, rapid pacing (RP) routine, and/or a back-up pacing (BP) routine, in response to user input from the RCM.

System and methods for providing a patient with arrhythmia treatment are described. For example, a system includes an arrhythmia monitoring and treatment assembly configured to be worn on the torso of the patient. The assembly has a housing discreetly extending from a skin surface of the patient. The assembly is configured to provide therapy on detecting one or more arrhythmia conditions of the patient. A first at least one user response button is disposed on the assembly at a first location on the torso concealed under clothing, and a second at least one user response button is configured to be worn on a second location of the patient's body, a location other than the torso that is accessible to the patient. The system suspends an impending therapy upon receiving a user input from either one of the first or second at least one user response buttons.

An assembly for placement of a cardiac, aortic or arterial implant. The assembly includes an insertion sheath of an introducer or of a delivery catheter, which is of a size smaller than that of an introducer, intended to be introduced into an artery of a human body. The metal support of an electrode of the external cardiac stimulator being integrated into the insertion sheath of a peripheral venous or arterial accessory catheter, or a sleeve around the accessory catheter, which is introduced into the peripheral vein or artery of a patient. The sheath of the accessory catheter or the sleeve is therefore directly in contact with a peripheral vein or artery of the patient.

An electrically conductive connection element for a temporary electrically conductive connection to an electrical consumer, in particular an external pacemaker, which is implanted in the living tissue of a patient, may have at least one biocompatible and bioresorbable electrical conductor strand in the form of an individual wire or a multifilament formed by multiple wires. The at least one electrical conductor strand is surrounded by at least one biocompatible and bioresorbable polymer or is embedded in a matrix formed by the polymer.

Switching systems are positioned along a bidirectional signal carrying line, typically between an electrode in a catheter at the heart of a patient, and an external console. The switching system provides for switching the bidirectional signal carrying line between: a main line, which carries acquired electrocardiac signals from the electrode of the catheter at the heart of the patent to the external console, via a switch unit; and, a bypass line, which carries pacing signals, directly from the external console to the electrode of the catheter. The bypass line provides an uninterrupted electrical connection between the electrode and the external console, thus avoiding the switch unit.

An implantable system includes an implantable medical device (IMD) and a non-transvenous lead that is configured to be implanted outside of a heart. The IMD includes an output configured to be connected at least to the lead, a current generator (CG) circuit configured to generate pacing pulses, a switching circuit coupled between the CG circuit and the output, one or more capacitors coupled in parallel with the CG circuit and the switching circuit, and a control circuit coupled to the CG circuit. The control circuit is configured to manage the CG circuit to generate the pacing pulses with a constant current at the output.

An ambulatory medical device configured to analyze heart rates in different operating modes includes a plurality of ECG sensing electrodes, a plurality of therapy electrodes and at least one processor configured to in a default operating mode, perform a default heart rate calculation for determining a heart rate of the patient for use in detecting a cardiac arrhythmia condition of the patient. The at least one processor is configured to change a device operating mode from a default mode based on detecting patient activity to an activity operating mode, and in the activity operating mode, perform a different heart rate calculation from the default heart rate calculation for determining the heart rate for use in detecting the cardiac arrhythmia condition of the patient during the activity operating mode. The at least one processor is configured to deliver the treatment in response to detecting the cardiac arrhythmia condition.

Apparatuses, systems and methods are provided that may include a system for patient monitoring and defibrillation. The system may include at least two defibrillation electrodes. The system may further include a first unit for physiological monitoring of a patient, including ECG monitoring circuitry for monitoring ECG of the patient. The first unit may store CPR chest compression data. The system may further include a second unit, separate from the first unit, which may communicatively couple with the first unit, for providing defibrillation pulses to the patient. The second unit may include a processor, communicatively coupled with the at least two defibrillation electrodes, for providing defibrillation pulses to the patient via the at least two defibrillation electrodes.

A patient-worn arrhythmia monitoring and treatment device includes a pair of therapy electrodes and at least one pair of sensing electrodes disposed proximate to the skin and configured to continually sense at least one ECG signal of the patient over an extended period of time. The device includes a therapy delivery circuit coupled to the pair of therapy electrodes and configured to deliver one or more therapeutic pulses. A controller coupled to therapy delivery circuit is configured to analyze the at least one ECG signal and detect one or more treatable arrhythmias and cause the therapy delivery circuit to deliver the one or more therapeutic pulses to the patient. At least one of the one or more therapeutic pulses is formed as a biphasic waveform delivering within 15 percent of 360 J of energy to a patient body having a transthoracic impedance from about 20 to about 200 ohms.

An apparatus for monitoring a patient post operation having electrically conducting leads which are adapted to extend from inside the patient. The leads having electrodes adapted to communicate with a heart of the patient and apply electrical signals to the heart. The electrodes providing cardiac signals to the computer in response to the electrical signals so the computer can determine in real time at least one of heart volume, end diastolic heart volume, end systolic heart volume, stroke volume, change in heart volume, change in stroke volume, contractility, respiration rate or tidal volume regarding the patient.
