High-Yield Points
- 1️⃣ Atrial systole (atrial contraction) occurs just before ventricular systole, completing ventricular filling (note: atrial contraction corresponds to the P wave, while the QRS complex marks the onset of ventricular systole).
- 2️⃣ Ventricular systole (ventricular contraction) follows the QRS complex, opening semilunar valves and ejecting blood into the aorta and pulmonary trunk.
- 3️⃣ Isovolumetric relaxation: ventricles relax, all valves close, no volume change – pressure falls rapidly.
- 4️⃣ Rapid filling (early diastole) – ventricular pressure < atrial pressure, blood flows through open AV (mitral/tricuspid) valves.
- 5️⃣ Diastole concludes with ventricular relaxation and passive filling before the next cycle.
Topic Title
Cardiac Cycle One-Liners
Rapid Lines
- Atrial systole → P wave / final filling
- Ventricular systole → QRS / ejection
- Isovolumetric relaxation → pressure drop
- Rapid filling → passive ventricular filling
- Diastole → ventricular relaxation phase
Exam Pearl
Recall that mitral and tricuspid valves open when atrial pressure exceeds ventricular pressure during early diastole (rapid filling).
How to Use This for Revision
Use this Cardiac cycle one-liners 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.
