12-lead ECG (paper speed: 25 mm/s) – Heart rate: ∼55/min – Regular sinus rhythm – Normal cardiac axis: positive (+) QRS complex polarity in leads I, II, and III – Broad and bifid P waves (P): referred to as “P mitrale” and suggestive of left atrial enlargement – SV2 (S) + RV5 (R) >3.5 mV: meets Sokolow-Lyon criteria for left ventricular hypertrophy – Left ventricular strain pattern: ST depression (ST) with T-wave inversion (T) in left-sided leads I and V4–V6 Positive Sokolow-Lyon criteria and left ventricular strain pattern are characteristic of left ventricular hypertrophy.

12-lead ECG (paper speed: 25 mm/s) of a patient with chronic thromboembolic pulmonary hypertension – Regular sinus rhythm with a heart rate of 68/min – Extreme right-axis deviation: QRS axis borderline negative in lead I and negative in aVF (ECG machine calculated axis is -94°) – Incomplete bundle branch block (QRS duration ∼110–120 ms) – Dominant R wave in lead V1 (∼0.8 mV), with deep S waves in leads V5 (∼1.5 mV) and V6 (∼0.9 mV) – Sokolow-Lyon criteria for right ventricular hypertrophy (RVH) are fulfilled: (R wave in V1 or V2) + (S wave in V5 or V6) ≥1.05 mV – ST depression in V3 to V5; T wave inversion in II, III, aVF These findings strongly suggest right ventricular hypertrophy.

A brief, irregular downward movement of the hands may appear. ⭐ It is an important sign of hepatic encephalopathy but is not specific to it. --- 4. PRECIPITATING FACTORS OF HE Always search for a precipitating factor. ⭐ GI bleeding ⭐ Infection / SBP ⭐ Constipation ⭐ Dehydration ⭐ Excessive diuresis ⭐ Electrolyte disturbance ⭐ Renal dysfunction ⭐ Sedative medications ⭐ Non-adherence to treatment --- 5. MANAGEMENT OF HEPATIC ENCEPHALOPATHY STEP 1 — LOOK FOR THE CAUSE Search for: - Infection - GI bleeding - Constipation - Renal failure - Electrolyte abnormalities - Dehydration - Drugs --- STEP 2 — TREAT THE PRECIPITANT Examples: SBP → appropriate antibiotics GI bleeding → control bleeding Constipation → bowel clearance Dehydration → correct volume status --- STEP 3 — LACTULOSE ⭐ First-line therapy for overt HE.

RIFAXIMIN ⭐ Add/use for recurrent or persistent HE despite appropriate lactulose therapy. --- 7. NUTRITION ❌ Routine prolonged protein restriction is not recommended. Patients with cirrhosis need: - Adequate calories - Adequate protein - Frequent meals - Prevention of sarcopenia --- 8. AMMONIA ⚠️ Important viva point: Blood ammonia levels: - May be elevated - Do not reliably correlate with severity - Should not be used alone to diagnose or grade HE Therefore: Treat the patient, not the ammonia number. --- 9.
