Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Area of Science:

Cardiology
Biomedical Engineering
Rehabilitation Medicine

Background:

Cardiovascular diseases (CVDs) are a major global health concern.
Cardiac rehabilitation (CR) is vital for managing CVDs.
Traditional Heart Rate Variability Biofeedback (HRVB) requires manual therapist input, limiting home-based CR accessibility.

Purpose of the Study:

To introduce "FreeResp", a novel remote human-computer collaborative HRVB system.
To enable autonomous Resonance Frequency (RF) adjustment for personalized interventions.
To support home-based CR for cardiovascular patients.

Main Methods:

Developed FreeResp with a simplified cognitive computational model for autonomous RF adjustment.
Integrated wearable technology and Internet of Things (IoT) for remote monitoring.
Incorporated tactile guidance (airbag) for diaphragmatic breathing assistance.

Main Results:

FreeResp achieved high consistency with conventional HRVB in RF value determination (22/24 samples).
One month of home-based RF breathing training with FreeResp significantly improved Heart Rate Variability (HRV) (p < 0.05).
The system demonstrated effectiveness in a home-based setting.

Conclusions:

FreeResp is a promising, accessible solution for home-based CR.
The system offers timely, precise interventions for cardiovascular health management.
FreeResp represents a novel approach to long-term cardiovascular care.
