Tachycardia
That's Correct!
It's Wrong!
During diastole, the heart relaxes and refills with blood. This is the phase of the cardiac cycle when the heart chambers are not contracting but rather preparing for the next contraction. The relaxation allows the chambers to fill with oxygenated blood returning from the lungs (in the left side of the heart) or deoxygenated blood returning from the body (in the right side of the heart). This refilling of blood is essential for the heart to pump efficiently and maintain adequate blood flow throughout the body.
