Summary
Meditation enhances heart coherence and electroencephalogram (EEG) alpha activity, indicating improved physiological synchrony. These findings suggest heart coherence is a key marker for the meditative state and overall well-being.
Area of Science:
- Neuroscience
- Psychophysiology
- Integrative Medicine
Background:
- Meditation is increasingly recognized for its potential health benefits.
- Understanding the physiological underpinnings of meditation is crucial for validating its effects.
- Autogenic meditation offers a structured approach to achieving a meditative state.
Purpose of the Study:
- To investigate significant physiological parameters of brain and heart during meditation.
- To explore electrophysiological changes associated with meditation.
- To determine the dynamic correlations between cardiac and brain activity during meditation.
Main Methods:
- 12 healthy volunteers participated in an 8-week autogenic meditation training.
- Electrophysiological data, including EEG and heart rate variability, were recorded.
- Analysis focused on heart coherence, relative EEG alpha power, and alpha lagged coherence.
Main Results:
- Significant increases in heart coherence, relative EEG alpha power, and alpha lagged coherence were observed during meditation.
- A significant slowing of parietal peak alpha frequency occurred.
- Heart coherence positively correlated with EEG alpha activities during meditation.
Conclusions:
- Heart coherence serves as a reliable cardiac marker for the meditative state.
- Increased heart coherence and EEG alpha activity suggest enhanced heart-brain synchronicity.
- These synchronized physiological changes may aid in recovering from homeostatic depletion.

01:20Regulation of Pulse
Pulse regulation involves physiological mechanisms that ensure adequate blood flow throughout the body. The heartbeat, regulated by the autonomic nervous system, is influenced by hormonal balance, physical activity, and emotional state.
01:25Correlation between ECG and Cardiac Cycle
The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

01:30Factors Influencing Heart Rate
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

01:19Conduction System of the Heart
Autorhythmicity is a term that refers to the heart's inherent ability to generate electrical signals and instigate muscle contractions. This self-regulating conduction system within the heart consists of two key components: the pacemaker cells and specialized conducting cells.
The pacemaker cells are located in two primary nodes: the sinoatrial (SA) node and the atrioventricular (AV) node. The SA node pacemaker cells can autonomously depolarize, triggering an action potential that leads to the...

01:31Regulation of Heart Rates
The regulation of heart rate is a complex process controlled by the autonomic nervous system (ANS), hormonal influences, and intrinsic cardiac mechanisms. The ANS has two main components: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

01:29Disturbances in Heart Rhythm
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...
