SYNCHRONIZATION OF ANTI-TACHYCARDIA PACING IN AN EXTRA-CARDIOVASCULAR IMPLANTABLE SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240042212 titled 'SYNCHRONIZATION OF ANTI-TACHYCARDIA PACING IN AN EXTRA-CARDIOVASCULAR IMPLANTABLE SYSTEM
Simplified Explanation
The abstract describes an implantable cardioverter defibrillator (ICD) system that detects and treats tachycardia (abnormally fast heart rate) in patients. Here is a simplified explanation of the abstract:
- The ICD system receives a cardiac electrical signal through an extra-cardiovascular sensing electrode vector.
- It detects tachycardia and determines the tachycardia cycle length from the cardiac electrical signal.
- Based on the tachycardia cycle length, the system sets an extended ATP (anti-tachycardia pacing) interval that is longer than the regular ATP interval.
- The ICD system delivers ATP pulses to the patient's heart through an extra-cardiovascular pacing electrode vector that is different from the sensing electrode vector.
- The ATP pulses include a leading ATP pulse delivered at the extended ATP interval after a cardiac event is sensed, followed by a second ATP pulse delivered at the regular ATP interval.
Potential applications of this technology:
- Treatment of tachycardia: The ICD system can effectively detect and treat tachycardia episodes in patients, helping to restore normal heart rhythm and prevent potentially life-threatening situations.
- Cardiac monitoring: The system's ability to sense and analyze cardiac electrical signals can provide valuable data for monitoring the patient's heart health and detecting any abnormalities.
Problems solved by this technology:
- Tachycardia management: The ICD system offers a solution for managing tachycardia by delivering ATP pulses at specific intervals, helping to restore normal heart rhythm without the need for more invasive procedures.
- Patient safety: By delivering ATP pulses through a different electrode vector, the system minimizes the risk of unintended pacing or interference with the sensing function, ensuring the safety and effectiveness of the treatment.
Benefits of this technology:
- Non-invasive treatment: The ICD system provides a non-invasive method for treating tachycardia, reducing the need for more invasive procedures such as cardioversion or ablation.
- Customizable treatment: The system allows for the adjustment of the ATP interval based on the tachycardia cycle length, providing a personalized treatment approach for each patient.
- Continuous monitoring: The ICD system continuously monitors the patient's heart rhythm, allowing for early detection and intervention in case of tachycardia episodes, improving patient outcomes and reducing the risk of complications.
Original Abstract Submitted
an extra-cardiovascular implantable cardioverter defibrillator (icd) system receives a cardiac electrical signal by an electrical sensing circuit via an extra-cardiovascular sensing electrode vector and senses cardiac events from the cardiac electrical signal. the icd system detects tachycardia from the cardiac electrical signal and determines a tachycardia cycle length from the cardiac electrical signal. the icd system determines an atp interval based on the tachycardia cycle length and sets an extended atp interval that is longer than the atp interval. the icd delivers atp pulses to a patient's heart via an extra-cardiovascular pacing electrode vector different than the sensing electrode vector. the atp pulses include a leading atp pulse delivered at the extended atp interval after a cardiac event is sensed from the cardiac electrical signal and a second atp pulse delivered at the atp interval following the leading atp pulse.
