Seismocardiography with Smartphones: No Leap from Bench to Bedside (Yet)

Executive Summary

This paper reviews the current state of smartphone-based seismocardiography (SCG) applications, highlighting the lack of clinical adoption despite technical feasibility demonstrated in laboratory settings. The authors conducted a systematic literature review and app store analysis, finding limited availability of SCG apps and identifying barriers such as insufficient clinical validation, lack of standardization, and competition from established methods like photoplethysmography (PPG). The study emphasizes the need for research-backed validation and standardization to bridge the gap between bench and bedside applications.

This study shows that while smartphones can measure heart vibrations, the technology isn’t ready for clinical use due to lack of validation and standardization compared to other methods like PPG.

Answer Machine Insights

Q: What are the main barriers to clinical adoption of smartphone-based SCG?

The main barriers include lack of clinical validation, absence of standardization, and competition from established methods like PPG.

Moreover, the HP community may be reluctant to smartphone SCG as there is a gap in clinical evidence through clinical trials with a sound design and appropriate sample size.

Q: How many SCG apps were identified in app stores?

Two SCG apps were identified in app stores.

Altogether, 96.534 apps were excluded from our analysis... The resulting 81 apps... However, 2 apps were included for deeper analysis as shown in Table 2.

Key Results

  • Only 2 SCG apps were identified in app stores, with limited clinical relevance.

  • 16 out of 18 reviewed studies were conducted in laboratory settings, highlighting the lack of bedside validation.
