Relationship between amplitude and timing of heart sounds and endocardial acceleration.

Objective: To study the correlation between heart sounds and peak endocardial acceleration (PEA) amplitudes and timings, by modulation of paced atrioventricular (AV) delay in recipients of dual chamber pacemakers.
Methods: Ten recipients of dual chamber pacemakers implanted for high-degree AV block were studied. Endocardial acceleration (EA) and phonocardiographic and electrocardiographic signals were recorded during performance of an AV delay scan in VDD and DDD modes.
Article Synopsis
- * Researchers created a new way to automatically adjust this timing and compared it to another method that uses ultrasound to see how well it works.
- * The results showed that the new method works pretty well, matching closely with the ultrasound results, which means it could help improve how pacemakers are set up for patients.
