Intended Use

The Powerheart AECD is intended to acquire the electrocardiograph rhythm for the detection of, and to provide treatment for, ventricular tachyarrhythmias of in-hospital patients who are at risk of Sudden Cardiac Arrest.

Device Story

Powerheart AECD monitors cardiac electrical activity via ECG or defibrillation electrodes; detects ventricular tachyarrhythmias using rate and morphology analysis; delivers cardioversion/defibrillation energy to restore normal rhythm. Used in-hospital; operated by clinicians. Physician programs detection/therapy criteria and energy levels. Device delivers up to nine pulse sequences; requires manual reset or specific rhythm criteria for further therapy. Output informs clinical decision-making regarding cardiac resuscitation; benefits patient by providing automated life-saving therapy for sudden cardiac arrest.

Clinical Evidence

Bench testing only. Evidence includes system validation, electrical safety, electromagnetic compatibility (EMC), environmental testing, and verification/validation of arrhythmia detection software and hardware components.

Technological Characteristics

Automated External Cardioverter Defibrillator. Components: defibrillator, defibrillation/ECG electrodes, patient cable, computer system, control panel, display, printer, event recorder. Energy: up to 360 Joules. Waveform: per AAMI DF2-1996. Connectivity: ECG out cable. Software: RHYTHMx arrhythmia detection algorithm. Operating modes: Automatic, Advisory, Manual, Program.

Indications for Use

Indicated for in-hospital patients at risk of Sudden Cardiac Arrest requiring detection and treatment of ventricular tachyarrhythmias.

Regulatory Classification

Identification

An automated external defibrillator (AED) system consists of an AED and those accessories necessary for the AED to detect and interpret an electrocardiogram and deliver an electrical shock (e.g., battery, pad electrode, adapter, and hardware key for pediatric use). An AED system analyzes the patient's electrocardiogram, interprets the cardiac rhythm, and automatically delivers an electrical shock (fully automated AED), or advises the user to deliver the shock (semi-automated or shock advisory AED) to treat ventricular fibrillation or pulseless ventricular tachycardia.

| Device Description | The Powerheart monitors a patient's cardiac electrical activity and detects and treats ventricular tachyarrhythmias. The patient is connected to the device by a patient cable which is attached to both a set of ECG electrodes and a set of defibrillation electrodes. The defibrillation electrodes can be positioned on the patient sternum- apex or anterior-posteriorly. The operator can program the device during set up to use either the ECG electrodes or the defibrillator electrodes to sense ECG. The Powerheart uses a combination of rate and, if programmed by the physician, morphology to determine the presence of shockable arrhythmias. When a shockable arrhythmia is detected, the system delivers cardioversion and/or defibrillation energy through defibrillator electrodes to restore normal cardiac rhythm. Should the arrhythmia continue, the Powerheart will deliver additional electrical countershocks after each subsequent evaluation and programmed delay. Depending upon the programmed parameters as prescribed by the physician, the Powerheart may deliver a maximum of nine pulse sequences. In the event that nine pulse sequences have been delivered, the Powerheart will not automatically deliver any further therapy until: 1) a new shockable rhythm is detected after 60 consecutive seconds of non-shockable rhythm is presented, or 2) the device is reset manually. The energy levels for each individual countershock are also programmed into the device per the physician's prescription. |

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices. good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
