Classically, S3 and S4 heart sounds have strongly indicated pathologies of the left ventricle, but due to their low frequency, timing, and low intensity, the sensitivity using a stethoscope was poor. in 2003, in the enhanced detection of the left ventricular enlargement using a combination of ECG and phonocardiography. The synthesis of the simultaneous analysis of ECG and digitally acquired heart sounds was first examined by Warner et al. The experiences using this user-friendly and cost-effective electro-acoustic cardiography are discussed. While some observational clinical studies have been carried out within the hospital, the technology holds the greatest potential as a screening tool for cardiovascular disease (CVD) prevention and management. Conventionally, these modalities are conducted separately however, subjecting these two orthogonal biosignals to simultaneous and concurrent analysis reveals a much greater degree of specificity in pointing to the causative factors of hemodynamic insufficiency within the heart detailing information regarding the systolic and diastolic left ventricular function. Available from: Įlectro-Acoustic Cardiography is a novel synthesis of two well-established diagnostic modalities electrocardiography (ECG) and phonocardiography.
