Understanding the Cardiac Cycle Phases is crucial if you are planning to understand Cardiac Disease more completely. Cardiac Cycle Phases can help one to understand the basics better of Cardiac Disease. Cardiac Cycle Phases can be briefly described as the four phases. Understanding each of the four phases helps an individual to make better-informed decisions regarding their Cardiac Health.
The Cardiac Cycle Phases are divided into four: The Right Atrium/ Airways Phase, the Center of Masses (the left atrium), the Circulating Particles, and the Peristalsis. Traditionally, Cardiac Cycle Phases have been taught to students as a series of brief lectures, followed by physiological assessment in the form of an exam. These lectures often use PowerPoint presentations, with images and moving illustrations. During the lessons, the instructor usually uses the term "PIP." For example, "the elevation of arterial pressure in your right atrium."
In the first phase, the Cardiac Cycle Phases ...

The high potassium concentration in the arterial blood provides ample conductivity for the passage of the pulse. After a few seconds, the arteries and the left atrium regain their average conductivity, and the heart failure pulse ceases. This second phase of the Cardiac Cycle Phases is called the contracting phase. Except for the increase in potassium levels, no other change can affect the cardiac cycle.
In the next phase of the cardiac cycle, called the palliative phase, the heartbeat begins to slow down. Gradually the blood pressure also begins to fall. When the heart rate begins to relax completely, this is the time for the heart's natural pacemaker to kick in and prepare the body for bedtime. In a matter of minutes, the heart will begin to relax, and the contractions will slow down. Once the hearts relaxation phase has been completed, the heart will slowly return to its resting phase.
In between the two Cardiac Cycle Phases, the Periodic Strain Phase occurs during atria. During atria, the blood continues to pump, and the blood pressure increases in a back and forth movement. When the atrium fills up completely, there is suddenly a drop in blood pressure, and the heart has to work twice as hard to pump blood.
Then comes the Gradual Relaxation Phase, the final phase in the cardiac cycle. During this stage, the ventricles are entirely relaxed and begin to contract slowly. This causes the valves to close off and lock, preventing the blood from flowing freely through the arteries. Because of the effort required to maintain the valves closed, mild hypertension develops. The result is the same as during the atria stage, however, with a decreased heart rate.
Finally, we have the Adrenal State Phase, which is the culmination of phases of cardiac cycle. The atria are full, and the ventilation process has been completed, however now the Ventricles begin to relax once more. Once the Ventricles have ultimately returned to their fully relaxed state, the pressure on the atria begins to decrease again. This decrease in blood pressure is the result of the body now using the atria for all of its energy needs. As long as the atria are open, this process will continue until the heart has had enough time to return to its resting period and then the cycle will begin again. The process is similar to the Ventricular Phases described previously.
Understanding how the Cardiac Cycle Phases work and how they affect the functioning of your heart is crucial to preventing sudden cardiac death or even cardiac arrest. If you are experiencing any of these symptoms, please seek immediate medical attention. If you attempt to self-treat your condition by trying to increase your heart rate and add stress to your heart, you will only cause further damage and possibly damage your ventricles permanently. Do not attempt to perform any of the previously described Cardiac Cycle Phases without the supervision of a Cardiac Therapist. A Cardiac Therapist is trained in Cardiac Cycle Phases and can help you understand what is happening with your heart, how to reverse its function, and how to reduce your risk of having a sudden cardiac arrest or even death.
