Cardiac Cycle One-Liners for Rapid Revision
High-yield rapid revision points and one-liners regarding the mechanical and electrical events of the cardiac cycle for professional examinations.
Quick Answer
High-yield rapid revision points and one-liners regarding the mechanical and electrical events of the cardiac cycle for professional examinations.
High-Yield Points
- Total duration of a normal cardiac cycle is 0.8 seconds at a heart rate of 72 beats per minute.
- Atrial systole lasts for 0.1 seconds, while ventricular systole occupies 0.3 seconds and ventricular diastole lasts 0.4 seconds.
- Isovolumetric contraction and isovolumetric relaxation are periods where all four heart valves remain closed.
- The maximum ventricular filling occurs during early rapid ventricular filling, accounting for about two-thirds of total filling.

Cardiac Cycle Quick Fire Facts
Rapid Lines
- Total duration: 0.8s
- Atrial systole: 0.1s
- Ventricular systole: 0.3s
- Total diastole: 0.4s
- S1 sound: AV valve closure
- S2 sound: Semilunar valve closure
Exam Pearl
Isovolumetric contraction and relaxation both feature closed valves, meaning no volume change occurs while pressure drastically shifts.
How to Use This for Revision
Use this Cardiac Cycle One-Liners for Rapid Revision page as an active-recall checkpoint rather than passive reading. Read the key section once, hide the answer or comparison column, recall the point aloud, and then check your response. Mark only the points you missed and revisit them in your next revision round. This keeps the page focused on learning value without adding unsupported facts.
Quick Recap
Before leaving this page, recall the main point in one sentence and review only the items you could not reproduce from memory.
