Cardiovascular diseases are the main cause of death worldwide, with sleep
disordered breathing being a further aggravating factor. Respiratory illnesses
are the third leading cause of death amongst the noncommunicable diseases. The
current COVID-19 pandemic, however, also highlights the impact of communicable
respiratory syndromes. In the clinical routine, prolonged postanesthetic
respiratory instability worsens the patient outcome. Even though early and
continuous, long-term cardiorespiratory monitoring has been proposed or even
proven to be beneficial in several situations, implementations thereof are
sparse. We employed our recently presented, multimodal patch stethoscope to
estimate Einthoven electrocardiogram (ECG) Lead I and II from a single 55 mm ECG
lead. Using the stethoscope and ECG subsystems, the pre-ejection period (PEP) and
left ventricular ejection time (LVET) were estimated. ECG-derived respiration
techniques were used in conjunction with a novel, phonocardiogram-derived
respiration approach to extract respiratory parameters. Medical-grade references
were the SOMNOmedics SOMNO HD(TM) and Osypka ICON-Core(TM). In a study including
10 healthy subjects, we analyzed the performances in the supine, lateral, and
prone position. Einthoven I and II estimations yielded correlations exceeding
0.97. LVET and PEP estimation errors were 10% and 21%, respectively. Respiratory
rates were estimated with mean absolute errors below 1.2 bpm, and the respiratory
signal yielded a correlation of 0.66. We conclude that the estimation of ECG,
PEP, LVET, and respiratory parameters is feasible using a wearable, multimodal
acquisition device and encourage further research in multimodal signal fusion for
respiratory signal estimation.
