4 results about "Antitachycardia Pacing" patented technology

The hybrid stimulation system is an electrical stimulation system serves to delivered an electrical stimulation impulse to the heart (human or animal heart) , using a combination of internal (intravascular) and external (body surface) electrodes, the hybrid electrical stimulation system can be used for pacing of the heart during slow heart beat (bradycardia), or shocking the heart during fast heart beat (Tachycardia) , or to terminate fast abnormal heart beat (tachy-arrhythmia) by means of override pacing (Anti-tachycardia pacing). This hybrid system can be used and introduced into the body without the need for imaging guidance such as fluoroscopy or echocardiography to insert the internal component, and does not require direct contact between the internal pacing wire and the myocardium (internal heart surface).

Antitachycardia pacing (ATP) therapy may be delivered to the cardiac conduction system using cardiac conduction system pacing therapy. An initial cardiac conduction system ATP pulse set including three or less cardiac conduction system ATP pulses may be delivered to the patient's cardiac conduction system. A first cardiac conduction system ATP pulse of the initial cardiac conduction system ATP pulse set may be delivered at an interval configured to provide maximal capture of the cardiac conduction system.

The present disclosure relates to synchronization of anti-tachyarrhythmia pacing in an extravascular implantable system. An extravascular implantable cardioverter defibrillator (ICD) system receives cardiac electrical signals through an extravascular sensing electrode vector by an electrical sensing circuit and senses cardiac events from the cardiac electrical signals. The ICD system detects a tachyarrhythmia from the cardiac electrical signals and determines a tachyarrhythmia cycle length from the cardiac electrical signals. The ICD system determines an ATP interval based on the tachyarrhythmia cycle length and sets an extended ATP interval that is longer than the ATP interval. The ICD delivers ATP pulses to the patient's heart via an extravascular pacing electrode vector that is different from the sensing electrode vector. The ATP pulses include a lead ATP pulse delivered at the extended ATP interval after a cardiac event is sensed from the cardiac electrical signals and a second ATP pulse delivered at the ATP interval after the lead ATP pulse.

A pacing device, a system comprising the pacing device and a method for operation of the pacing device, wherein the pacing device comprises a housing, a processor and a receiver electrically connected to the processor, wherein the processor is adapted todeliver signals for electric stimulation of a patient's heart according to at least one first stimulation mode anddeliver signals for electric stimulation of the patient's heart according to an antitachycardiac pacing mode (ATP mode), wherein the ATP mode is initially deactivated and / or is to be upgraded,wherein the receiver is adapted to receive an ATP confirmation signal transmitted by an external device or produced by operation of an actuator accommodated at the housing of the pacing device,wherein the processor is adapted to upgrade the ATP mode and / or to activate the ATP mode only if the ATP confirmation signal comprises a pre-defined confirmation information.
