RHYTHMx™ technology

Making hard decisions fast

The RHYTHMx technology offers the most advanced, smartest software analysis algorithm in the industry. The RHYTHMx technology is the intelligence behind the Cardiac Science's Powerheart hospital and public access defibrillation products, and is designed to continuously monitor, detect, and advise defibrillation therapy to treat cardiac arrhythmias.

• Specificity and Sensitivity - clinical results with the RHYTHMx technology demonstrated 100% sensitivity (correct identification of shockable rhythms) and 99.4% specificity (correct identification of non-shockable rhythms).
• RHYTHMx technology differentiates between shockable life-threatening cardiac rhythms such as ventricular arrhythmias (VT/VF) and supraventricular tachyarrhythmias (SVT), plus distinguishes non-shockable cardiac arrhythmia events.
• Non-committed device - If the RHYTHMx technology detects a shockable rhythm and charges, but recognises a rhythm change, the Cardiac Science device automatically disarms, informs the user that that the rhythm has changed, and reanalyses the patient's heart rhythm.
• Post-resuscitation monitoring - RHYTHMx technology continues to monitor the patient's heart rhythm post resuscitation, to instantly detect the reoccurrence of a life-threatening arrhythmia. If cardiac arrest recurs, the Cardiac Science device will charge automatically and advise the operator to deliver a defibrillation shock.
• Synchronised shock - RHYTHMx technology automatically synchronises shock delivery whenever possible to the patient's electrocardiogram R-wave. If unable to synchronize it will deliver an unsynchronised shock. Synchronisation of a defibrillation shock has been shown to be more effective in converting patients out of life threatening arrhythmias.
• RHYTHMx Technology that allows a medical director or physician to pre-program detection rates for shockable cardiac arrhythmias such as VF, VT and SVT.
