🧠 2️⃣ Mnemonics
Mnemonic Title: AV Valves
Mnemonic Word:
“Try Pulling My Valve”
Meaning:
Tricuspid → Pulmonary → Mitral → Aortic
Mnemonic Title: Heart Sounds
Mnemonic Word:
“Lub = AV, Dub = SL”
Meaning:
S1 (Lub) = AV valve closure
S2 (Dub) = Semilunar valve closure
Mnemonic Title: ECG Sequence
Mnemonic Word:
“P-QRS-T”
Meaning:
P → Atrial depolarization
QRS → Ventricular depolarization
T → Ventricular repolarization
Mnemonic Title: Cardiac Cycle Flow
Mnemonic Word:
“Fill → Close → Eject → Relax”
Meaning:
Filling → AV closure → Ventricular ejection → Relaxation
📋 3️⃣ Memory Tables
Table 1 — S1 vs S2
| Feature | S1 | S2 |
|---|---|---|
| Valve Closure | Mitral + Tricuspid | Aortic + Pulmonary |
| Timing | Beginning of systole | Beginning of diastole |
| Sound | Lub | Dub |
Table 2 — Stenosis vs Regurgitation
| Feature | Stenosis | Regurgitation |
|---|---|---|
| Main Problem | Narrow opening | Backflow |
| Hemodynamic Effect | Pressure overload | Volume overload |
| Murmur Cause | Obstructed flow | Reverse flow |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• S1 occurs at start of ventricular systole
• S2 occurs at start of ventricular diastole
• QRS complex precedes ventricular contraction
• Coronary perfusion mainly occurs during diastole
• AV valves open during ventricular filling
• Semilunar valves open during ventricular ejection
• Tachycardia reduces ventricular filling time
• Aortic stenosis causes pressure overload
• Regurgitation causes volume overload
• Cardiac muscle depends heavily on oxygen
• Papillary muscles stabilize AV valves
• Mitral stenosis commonly causes breathlessness
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook:
Mitral stenosis → Pulmonary congestion and diastolic murmur
Clinical Hook:
Aortic stenosis → Left ventricular hypertrophy and systolic murmur
Clinical Hook:
Aortic regurgitation → Volume overload of left ventricle
Clinical Hook:
Chordae tendineae rupture → Mitral valve prolapse
Clinical Hook:
Tachycardia → Reduced ventricular filling
