I now have all the information needed for a thorough analysis. Let me compile the complete response.

ECG Analysis - 28-Year-Old African Male, Chest + Back Pain x 2 Days

Machine Measurements (from ECG header)

  • Heart rate: ~58 bpm (RR 1036 ms) - sinus bradycardia
  • PR interval: 55 ms (short - likely machine artifact or measurement at fast segment)
  • QRS duration: 74 ms (normal)
  • QT/QTc: 40 degrees axis (normal)
  • Speed: 25 mm/s | Gain: 10 mm/mV

Key ECG Findings

1. ST Segment Elevation (Diffuse)
  • ST elevation is present across multiple leads: I, II, aVF, V2-V6
  • The morphology appears concave (saddle-shaped/upward concavity) - the ST segment curves upward rather than the convex "tombstone" pattern of STEMI
  • Elevation appears most prominent in the mid-precordial leads (V3-V5)
  • No reciprocal ST depression in opposing leads (e.g., no depression in aVL or V1) - which would be expected in true STEMI
2. PR Segment Changes
  • There appears to be PR depression visible, particularly in inferior leads - a specific (though insensitive) marker of pericarditis
3. T Waves
  • T waves are tall, peaked, and concordant with the ST elevation - upright and prominent
  • No T-wave inversion
4. QRS Complex
  • Notching at the J point (junction of QRS and ST segment) is visible in precordial leads - characteristic of early repolarization
  • No pathological Q waves
5. No Focal Changes
  • The ST elevation is diffuse (multiple non-contiguous territories), not localized to a single coronary territory

Differential Diagnosis

Given the ECG pattern + clinical context (28M, African, 2 days of chest AND back pain), the top differentials in order of probability and urgency:
PriorityDiagnosisSupporting FeaturesAgainst
URGENTAortic DissectionChest + back pain, young African male, 2 daysECG relatively benign; no widening visible on this ECG alone
HighAcute Pericarditis/MyopericarditisDiffuse concave ST elevation, PR depression, young male, likely viral/TB (in Africa TB pericarditis up to 70%)Back pain less typical
ModerateSTEMIChest pain, ST elevationDiffuse not focal, concave not convex morphology, no reciprocal changes
LowerBenign Early Repolarization (BER)Young African male (higher prevalence), J-point notching, concave STSymptoms for 2 days makes this a diagnosis of exclusion

Critical Point on Aortic Dissection

This cannot be dismissed. Chest AND back pain in a young African male is a RED FLAG for aortic dissection (Type A or B). African males have higher rates of hypertension-related aortic disease, and connective tissue disorders (Marfan syndrome) must be considered. The ECG in aortic dissection can look entirely normal OR show ST elevation if the dissection extends into a coronary ostium (usually RCA - causing inferior ST elevation).
"Aortic dissection can be manifested with chest pain radiating to the back." - Goldman-Cecil Medicine

Pericarditis ECG Interpretation (Textbook)

The pattern here is most consistent with acute pericarditis Stage 1, characterized by:
  • Diffuse ST elevation (concave morphology)
  • PR segment depression
  • No Q waves
  • No reciprocal changes
Per Rosen's Emergency Medicine: "Benign early repolarization (BER) is a normal electrocardiographic variant... BER includes: (1) ST segment elevation; (2) upward concavity of the initial portion of the ST segment; (3) notching of the terminal portion of the QRS complex at the J point; (4) symmetric concordant T waves of large amplitude; (5) diffuse ST segment elevation."
Per Braunwald's Heart Disease: "Typical ECG evolution [in pericarditis] follows four stages: (1) PR depression and/or diffuse ST segment elevation, (2) normalization of ST segment, (3) T wave inversion with or without ST segment depression, and (4) normalization."
Importantly, in Africa, TB is the leading cause of pericarditis (up to 70% of cases), compared to <4% in developed countries. This patient's presentation demands TB pericarditis be actively ruled out.

Recommended Workup (Urgent)

  1. Immediate: CT angiography of the chest/aorta to rule out aortic dissection - given the back pain, this is non-negotiable
  2. Troponin, CK-MB - to assess for myocardial injury (myopericarditis)
  3. CRP, ESR, FBC - inflammatory markers
  4. Chest X-ray - cardiac silhouette (>300 mL effusion enlarges it), mediastinal widening (dissection)
  5. Echocardiography - pericardial effusion assessment (present in ~60% of pericarditis cases)
  6. TB workup - Quantiferon/TST, sputum AFB, HIV status (critical in African context)
  7. Repeat ECG - serial ECGs to track evolution

Bottom Line

This ECG shows diffuse concave ST elevation with likely PR depression - most consistent with acute pericarditis (Stage 1), with benign early repolarization as a competing explanation. However, the 2-day history of chest AND back pain in this demographic mandates urgent exclusion of aortic dissection and TB pericarditis before settling on a benign diagnosis.
Do not discharge this patient based on ECG alone. CT aorta and echo are the next immediate steps.

Here is a full ECG interpretation:

ECG Interpretation

Machine Measurements (from header)

ParameterValue
Heart Rate96 bpm
QRS Duration102 ms (borderline prolonged)
QT / QTc332 / 377 ms (normal)
P/QRS/T axis71 / 53 / 43° (all normal)
RV5/SV1 amplitude2.14 / 1.34 mV
RV5 + SV13.48 mV
Speed / Gain25 mm/s, 10 mm/mV (standard)
Precordial gain5 mm/mV (half standard - important!)

Systematic Analysis

1. Rate & Rhythm

  • Rate is 96 bpm - normal sinus rhythm, at the upper end of normal
  • Rhythm appears regular with upright P waves preceding each QRS in lead II
  • Normal sinus rhythm

2. Axis

  • P axis: 71° - normal
  • QRS axis: 53° - normal (no axis deviation)
  • T axis: 43° - normal

3. P Waves

  • P waves appear present and upright in I, II, aVF
  • Normal morphology - no evidence of atrial enlargement visible

4. PR Interval

  • Appears normal (~160-180 ms)

5. QRS Complex - KEY FINDING

  • QRS duration 102 ms - borderline (normal <100 ms; this is at the threshold)
  • Very high voltage in precordial leads, particularly V2-V5
  • The precordial gain is marked at 5 mm/mV (half standard). This means the actual QRS amplitudes are DOUBLE what appears on the trace
  • Machine reports RV5 + SV1 = 3.48 mV = 34.8 mm - this already meets Sokolow-Lyon criteria for LVH (>3.5 mV = 35 mm). At full gain, the apparent precordial voltages would be even more striking
  • Tall R waves in V4-V6, deep S waves in V1-V2

6. ST Segments & T Waves - KEY FINDING

  • In the lateral leads (V5, V6, I, aVL): there is ST depression with asymmetric T-wave inversion
  • This is the classic LVH strain pattern (formerly "left ventricular strain")
  • The ST depression is downsloping with negative T waves in leads with the tallest R waves - hallmark of pressure-overload repolarization abnormality
  • No focal ST elevation suggesting acute infarction

7. QT Interval

  • QTc 377 ms - normal (normal <440 ms in males)

Primary Diagnosis

Left Ventricular Hypertrophy (LVH) with Strain Pattern

Criteria met:
  • Sokolow-Lyon: RV5 + SV1 = 3.48 mV (threshold >3.5 mV - borderline, but note the 5 mm/mV precordial gain means actual voltage is higher)
  • Cornell voltage: RaVL + SV3 - would need to measure precisely, but high voltages throughout suggest this is exceeded
  • Strain pattern: ST depression + T-wave inversion in lateral leads (I, aVL, V5-V6)
Per Harrison's Principles: "Multiple voltage criteria for left ventricular hypertrophy have been proposed based on the presence of tall left precordial R waves and deep right precordial S waves (SV1 + RV5 or RV6 >35 mm). Repolarization abnormalities (ST depression with T-wave inversions, formerly called the left ventricular 'strain' pattern) may appear in leads with prominent R waves."
LVH vs RVH ECG patterns
LVH: deep S in V1, tall R in V6, with strain-pattern ST-T changes (Harrison's)

Summary Table

High precordial voltageLVH (Sokolow-Lyon borderline/met)
Lateral ST depression + T inversionLVH strain pattern
No Q wavesNo evidence of prior MI

Clinical Implications

  1. LVH with strain strongly suggests chronic pressure or volume overload - the most common cause is systemic hypertension. Other causes include aortic stenosis, hypertrophic cardiomyopathy (HCM), and coarctation of the aorta
  2. LVH with strain is an independent cardiovascular risk factor - associated with increased risk of heart failure, ventricular arrhythmias, and sudden cardiac death
  3. Workup recommended:
    • Blood pressure measurement (both arms)
    • Echocardiogram - to confirm LVH, assess wall thickness, EF, valves, and rule out HCM
    • Renal function (hypertensive nephropathy)
    • Urinalysis for proteinuria
    • Fasting lipids and glucose
