🫀 Cardiac Output by Echo — Quick Summary

▪︎ LVOT Area = π × (LVOT diameter / 2)²
▪︎ Stroke Volume (SV) = LVOT area × LVOT VTI
▪︎ Cardiac Output (CO) = SV × HR

📊 Normal Values

▪︎ LVOT VTI: 18–22 cm
▪︎ CO: 4–8 L/min
▪︎ Cardiac Index (CI): 2.5–4 L/min/m²

🔄 Volume Responsiveness (Passive Leg Raise 30–90 sec)

▪︎ SV or CO ↑ >15%
▪︎ VTI ↑ >12.5%

This predicts fluid responsiveness without giving fluids.

“If VTI rises with legs, fluids help.”

The Sinoatrial (SA) Node, known as the natural pacemaker of the heart, is a specialized cluster of pacemaker cells located in the right atrium at the junction of the superior vena cava and near the crista terminalis. It has the unique property of automaticity, allowing it to generate electrical impulses spontaneously without any external stimulation. These impulses initiate atrial depolarization, represented by the P wave on ECG, and establish the normal rhythm of the heart.
The SA node generates impulses at an intrinsic rate of 60–100 beats per minute, making it the fastest pacemaker and the primary controller of heart rate. Its pacemaker action potential is characterized by spontaneous Phase 4 depolarization due to funny sodium (If) currents and calcium influx, rapid depolarization via L-type calcium channels, and repolarization through potassium efflux. Unlike ventricular muscle cells, depolarization in SA nodal cells depends mainly on calcium ions rather than fast sodium channels.
Once generated, the impulse spreads through the atrial myocardium to the AV node, Bundle of His, bundle branches, and Purkinje fibers, ensuring coordinated atrial and ventricular contraction. The activity of the SA node is precisely regulated by the autonomic nervous system—sympathetic stimulation increases heart rate, while parasympathetic (vagal) stimulation decreases it. The SA node is primarily supplied by the right coronary artery in most individuals.
Any dysfunction of the SA node can lead to rhythm disturbances such as sick sinus syndrome, bradycardia, or SA nodal block, and in such cases, secondary pacemakers like the AV node may take over at a slower rate.

Ventricular tachycardia (also known as VT or V-tach) is a poorly perfusing rhythm, so patients may present with or without a pulse. It often presents with hemodynamic instability, which requires emergent intervention to restore a perfusing rhythm. When VT hits, it’s easy to feel overwhelmed. Think of LAMB to help you remember the most common treatments:

-L: Lidocaine, useful in ischemic VT and when amiodarone fails or is contraindicated.

- A: Amiodarone, commonly used for stable monomorphic VT.

- M: Magnesium sulfate, go-to for polymorphic VT and torsades de pointes, even if Mg level is normal.

- B: Beta-blockers/“Bang”. Beta-blockers are used for prevention of recurrent VT. “Bang” refers to cardioversion/defibrillation. Remember that cardioversion is only effective for unstable VT with a pulse. In pulseless VT or ventricular fibrillation, defibrillation is needed.

Criteria Diagnostic of Severe Tricuspid Regurgitation

1️⃣ Right-sided chamber enlargement
IVC diameter > 2.5 cm
RA area > 18 cm²
In the absence of ASD or pulmonic valve disease
🔎 Indicates chronic volume overload of the right atrium due to severe TR.

2️⃣ Color Doppler severity
Jet area > 10 cm²
Vena contracta width > 7 mm
📌 Large central jet + wide vena contracta = significant regurgitant orifice.

3️⃣ Hepatic vein systolic flow reversal
Systolic flow reversal in hepatic veins
Must be interpreted in sinus rhythm
Exclude:
AV dissociation
Ventricular pacing
Atrial arrhythmias
💡 This is a very specific sign of severe TR — reflects systolic backflow into systemic venous circulation.

4️⃣ Continuous-Wave (CW) Doppler pattern
▪︎ Dense triangular TR signal
▪︎ Density equal to or greater than tricuspid inflow
▪︎ Early peaking triangular shape (rapid RV–RA pressure equalization)
📌 Suggests large regurgitant volume and rapid pressure equalization.

Cardiac Tamponade – Mitral & Tricuspid Inflow Variation with respiration (Doppler Echo)

🫀 1️⃣ Mitral Valve Inflow
During inspiration (insp) → Mitral E-wave decreases
During expiration (exp) → Mitral E-wave increases
📊 Mitral Flow Variation
Normal: < 15%
Tamponade: > 30%
👉 In tamponade, exaggerated interventricular dependence causes LV filling to drop markedly during inspiration.

🫀 2️⃣ Tricuspid Valve Inflow
During inspiration (insp) → Tricuspid E-wave increases
During expiration (exp) → Tricuspid E-wave decreases
📊 Tricuspid Flow Variation
Normal: < 25%
Tamponade: > 60%
👉 RV filling increases during inspiration due to increased venous return, but the noncompliant pericardial space shifts the septum leftward, compromising LV filling.

📐 Formula for Flow Variation

Flow Variation = [(Exp - Insp)/Exp] x 100

Measured using peak E-wave velocities.

🧠 Why This Happens (Pathophysiology)
In cardiac tamponade:
▪︎ Pericardial pressure is elevated.
▪︎ Ventricles compete for limited space.
▪︎ Inspiration → RV expands → septal shift → LV filling drops.
▪︎ This produces exaggerated respiratory inflow variation (echo equivalent of pulsus paradoxus).

🔎 Clinical Pearl
Marked respiratory variation in mitral and tricuspid inflow on Doppler strongly supports hemodynamically significant tamponade, especially when combined with:
▪︎ RA Systolic /RV diastolic collapse
▪︎ Plethoric IVC
▪︎ Clinical hypotension
