Intended Use

The Heartstream XL Defibrillator/Monitor is a fully featured, defibrillator intended for use by qualified medical personnel, trained in either Advanced Cardiac Life Support or in the operation of the device, in a hospital environment.

Device Story

Heartstream XL is a manual defibrillator/monitor for hospital use by ACLS-trained clinicians. It delivers biphasic truncated exponential (BTE) waveform shocks for external/intra-thoracic defibrillation, synchronized cardioversion, and noninvasive pacing. Device also provides SpO2 monitoring. Clinicians operate the device to select energy levels and modes based on patient cardiac rhythm. Output informs immediate clinical intervention for cardiac arrest, tachyarrhythmias, and bradycardia, aiming to restore normal cardiac rhythm and improve patient survival.

Clinical Evidence

Bench testing and animal studies provided. Waveform analysis compared Heartstream XL BTE performance to LIFEPAK 12 BTE at various energy and impedance levels. Animal testing in domestic swine compared performance between the two devices. Clinical trial data for the SMART Biphasic waveform in adults at 150J for ventricular tachyarrhythmias and cardioversion of atrial fibrillation is cited as supporting evidence. No new clinical trials were conducted for this specific submission.

Technological Characteristics

Manual defibrillator/monitor utilizing Biphasic Truncated Exponential (BTE) waveform technology. Features include external/intra-thoracic defibrillation, synchronized shock delivery, noninvasive pacing, and SpO2 monitoring. Device is designed for hospital use by trained personnel.

Indications for Use

Indicated for termination of ventricular tachycardia and ventricular fibrillation in patients. AED therapy indicated for suspected cardiac arrest in patients ≥8 years old who are unresponsive, pulseless, and not breathing. Manual defibrillation indicated for pulseless, unresponsive patients. Synchronized defibrillation indicated for atrial fibrillation. Noninvasive pacing indicated for symptomatic bradycardia and asystole. SpO2 monitoring indicated for assessing oxygen saturation. Use by qualified medical personnel trained in BLS, ACLS, or defibrillation; must be used by or on the order of a physician. No clinical studies for pediatric applications.

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.

#### Intended Use

, l

The Heartstream XL Defibrillator/Monitor is a fully featured, defibrillator intended for use by qualified medical personnel, trained in either Advanced Cardiac Life Support or in the operation of the device, in a hospital environment.

# Comparison of Technology Characteristics

The Heartstream XL's Biphasic Truncated Exponential waveform utilized for intrathoracic defibrillation shocks, is similar to the BTE waveform used in the LIFEPAK 12.

## Nonclinical Tests Used in Determination of Substantial Equivalence

The testing performed to show substantial equivalence to the Lifepak 12 included:

- Waveform analysis, comparing the performance of the Heartstream XL BTE . waveform to the LifePak 12 BTE waveform at various energy and impedance levels typical of intra-thoracic applications.
- . Animal test data, comparing the performance of the Heartstream XL BTE to the Likepak 12 BTE in domestic swine.

# Conclusion from Testing

Based on the results of the testing described above, it is concluded that the Heartstream XL BTE waveform for intra-thoracic defibrillation applications does not raise any different questions regarding the safety or effectiveness as compared with the predicate devices. It is considered to be substantially equivalent to the predicate devices.

# Indications for Use

510(k) Number (if known): To be assigned

Device Name: Philips Medical Systems, Heartstream XL Defibrillator/Monitor

Indications For Use: The Heartstream XL Defibrillator/Monitor is for use for the termination of ventricular tachycardia and ventricular fibrillation.

The device is for use by qualified medical personnel trained in the operation of the device and qualified by training in basic life support, advanced cardiac support, or defibrillation. It must be used by or on the order of a physician.

The SMART Biphasic waveform utilized in the Heartstream XL Defibrillator/Monitor has previously undergone clinical testing in adults. These trials support the waveform's effectiveness for defibrillation of ventricular tachyarrhythmias at 150J.

AED Therapy: To be used in the presence of a suspected cardiac arrest on patients of at least 8 years of age that are unresponsive, not breathing and pulseless.

Manual Defibrillation: Asynchronous defibrillation is the initial treatment for ventricular fibrillation and ventricular tachycardia in patients that are pulseless and unresponsive. The SMART Biphasic waveform utilized in the Heartstream XL Defibrillator/Monitor incorporates some user selectable lower energy levels that were not used in the clinical trials.

Synchronized defibrillation is indicated for termination of atrial fibrillation. The SMART Biphasic waveform utilized in the Heartstream XL has undergone clinical testing demonstrating its safety and effectiveness for cardioversion of atrial fibrillation.

There are currently no clinical studies related to the use of SMART Biphasic waveform in pediatric applications.

Pacing: Noninvasive pacing is one method of treating patients with symptomatic bradycardia. It can also be helpful in patients with asystole, if performed early.

SpO2 Monitoring: SpO2 monitoring is indicated for use when it is beneficial to assess a patient's oxygen saturation level.
