Mind Map for Cardiac Cycle

A Visual Guide to the Cardiac Cycle with Mind Map

Your heart's a rhythmic wonder, but how does it keep the beat? This blog unlocks the secrets of the cardiac cycle with a handy mind map!

Explore the different phases, from relaxation to contraction, and visualize how blood efficiently pumps throughout your body.

Here is a more detailed and comprehensive mind map of the physiology topic “Cardiac Cycle”:

Central Idea: Cardiac Cycle

Main Branches:

Diastole
Systole
Cardiac Cycle Phases
Pressure and Volume Changes
Electrical Events
Mechanical Events

Sub-Branches:

1. Diastole

Early Diastole
- Isovolumic relaxation
- Rapid filling phase
  - Ventricular pressure decrease
  - Atrial pressure decrease
- Ventricular filling
  - Blood flow from atria to ventricles
  - Increased ventricular volume
Mid-Diastole
- Diastasis (slow filling phase)
  - Decreased ventricular pressure
  - Decreased atrial pressure
- Atrial contraction
  - Increased atrial pressure
  - Increased ventricular filling
Late Diastole
- End-diastolic volume (EDV)
  - Maximum ventricular volume
- End-diastolic pressure (EDP)
  - Minimum ventricular pressure

2. Systole

Isovolumic Contraction
- Ventricular contraction without volume change
  - Increased ventricular pressure
  - Decreased ventricular volume
Ejection Phase
- Ventricular contraction with volume change
  - Blood ejection into aorta and pulmonary artery
  - Increased aortic and pulmonary artery pressure
Protodiastole
- Early relaxation phase
  - Decreased ventricular pressure
  - Decreased aortic and pulmonary artery pressure

3. Cardiac Cycle Phases

Atrial Systole
- Atrial contraction
  - Increased atrial pressure
  - Increased ventricular filling
Ventricular Systole
- Ventricular contraction
  - Increased ventricular pressure
  - Blood ejection into aorta and pulmonary artery
Diastasis
- Slow filling phase
  - Decreased atrial and ventricular pressure

4. Pressure and Volume Changes

Pressure Changes
- Ventricular pressure
  - Increased during systole
  - Decreased during diastole
- Atrial pressure
  - Increased during atrial systole
  - Decreased during diastole
- Aortic pressure
  - Increased during systole
  - Decreased during diastole
Volume Changes
- End-diastolic volume (EDV)
  - Maximum ventricular volume
- End-systolic volume (ESV)
  - Minimum ventricular volume
- Stroke volume (SV)
  - Volume of blood ejected per beat

5. Electrical Events

P-Wave
- Atrial depolarization
  - Atrial contraction
QRS Complex
- Ventricular depolarization
  - Ventricular contraction
T-Wave
- Ventricular repolarization
  - Ventricular relaxation

6. Mechanical Events

Atrial Kick
- Atrial contraction
  - Increased ventricular filling
Ventricular Contraction
- Ventricular contraction
  - Blood ejection into aorta and pulmonary artery
Ventricular Relaxation
- Ventricular relaxation
  - Decreased ventricular pressure

Conclusion:

The cardiac cycle is a complex process that involves the coordinated contraction and relaxation of the heart’s atria and ventricles.

Understanding the different phases of the cardiac cycle, including diastole and systole, is essential to appreciate the mechanisms that regulate cardiac function and blood flow.

The cardiac cycle is a critical component of the cardiovascular system, and its proper functioning is essential for maintaining overall health.
