Outcome
Phonocardiographic characteristics and timing of physiological events in the cardiac cyclesurrogate
Phonocardiography in patients with multiple Starr-Edwards valves allows precise timing of cardiac events and reveals the negative impact of tachycardia during atrial fibrillation on valve function.
