Why we need to monitor the Heart Rate Variability HRV and ECG at home?
Heart rate variability HRV detection
Heart rate variability (HRV) is one of the non-invasive electroencephalographic monitoring indicators that has received considerable attention in recent years, and its physiological impact on HRV
Extensive and in-depth research has been conducted on its pathological significance, and the results indicate that heart rate variability signals contain information related to cardiovascular regulation
Analysis of HRV can indirectly and quantitatively evaluate the tension and balance of myocardial sympathetic and vagus nerves, which is important information in the section
Balance, and it can also analyze the activity of the autonomic nervous system. Heart rate variability can also serve as an independent cardiac source
Predictive indicators for the risk of sudden sexual death. Simultaneous analysis of heart rate variability for prognostic assessment and medication of multiple malignant arrhythmia
The analysis of therapeutic effects has a guiding role. So, research on HRV can greatly promote human understanding of cardiovascular disease
Understand and achieve results in the prevention and treatment of cardiovascular diseases.
Research Methods of HRV
With the continuous deepening of research on HRV, the physiological and pathological information it contains will be further revealed, making HRV
There is more application space and value. At present, the main methods for analyzing heart rate variability are time-domain analysis and frequency-domain analysis，time-frequency analysis, and nonlinear analysis methods
(1) Sudden cardiac death (SCD) prediction: As HRV is the most sensitive indicator reflecting autonomic nervous system tension
Reduced HRV is the most valuable independent indicator for predicting sudden cardiac death.
(2) Risk assessment of patients after acute myocardial infarction: Reduction of HRV predicts the occurrence of heart disease in patients after acute myocardial infarction
An important independent indicator of the risk of sudden cardiac death and malignant arrhythmia. It is generally recommended to start HRV one week after the stroke
Detection of. HRV immediately decreases after infarction and begins to recover within a few weeks (gradually recovering after 2 weeks), approximately 6-12
Returned to normal within a month. Therefore, multiple measurements of HRV may have greater value than a single measurement. The speed of recovery of HRV after infarction
It also has predictive value for the risk of future death.
(3) Evaluation of autonomic nervous system injury in patients with diabetes: diabetes patients are different regardless of their severity
The degree of autonomic dysfunction. HRV is the most accurate way to judge whether patients with diabetes have autonomic nervous system damage,
The most sensitive indicator.
(4) Risk assessment of patients with heart failure (CHF).
(5) Heart rate variability biofeedback therapy: improves the chances of conception in infertile individuals and improves pregnancy anxiety in pregnant individuals
The relief of postpartum depression in the elderly and postpartum population has played a good role.
(6) Other clinical applications: angina pectoris, hypertension, cardiomyopathy, chronic severe bicuspid caused by non deficient heart disease
Cardiovascular diseases such as valve regurgitation, mitral valve prolapse, arrhythmia, and vasovagal syncope.
