anterior myocardial infarction ECG 12 lead poor R wave progression

A standard 12-lead electrocardiogram (ECG) displayed on a pink grid. The tracing demonstrates a sinus rhythm with several diagnostic abnormalities. In the precordial leads (V1-V6), there is evidence of poor R-wave progression, characterized by low-amplitude R waves that fail to increase appropriately across the chest leads. Pathological Q-waves are present in the anterior and lateral leads (V1 through V6), suggesting a prior anterolateral myocardial infarction or significant underlying cardiomyopathy. The voltage across the leads is generally low. Morphological changes in the P-waves are visible, specifically a biphasic P-wave in lead II and a prominent negative terminal deflection of the P-wave in lead V1, which are classic indicators of left atrial enlargement (P mitrale). A premature atrial contraction (PAC) is also observable in the rhythm strip. This diagnostic image is intended for medical students and clinicians to recognize patterns of atrial enlargement, poor R-wave progression, and low-voltage ECG readings in the context of cardiovascular pathology.

A 12-lead electrocardiogram (ECG) trace presented on standard grid paper, demonstrating several pathological findings. The rhythm is sinus with a heart rate of approximately 97 bpm. Key features include low QRS voltage in the frontal plane leads (I, II, III, aVR, aVL, aVF) and a notable poor R-wave progression across the precordial leads, specifically from V1 to V4, where the R-wave fails to gain amplitude; this finding is highly suggestive of an electrically inactive area in the anterior myocardial wall. P-wave morphology in leads II and V1 indicates left atrial overload, characterized by increased duration and potential notching. Additionally, the ECG shows indirect signs of right atrial overload (Peñaloza-Tranchesi sign) and diffuse non-specific ST-segment and T-wave abnormalities indicating ventricular repolarization changes. These findings collectively suggest chronic cardiac remodeling, potentially secondary to dilated cardiomyopathy or an old anterior wall myocardial infarction.

A standard 12-lead electrocardiogram (ECG) displayed in a 3x4 layout plus a rhythm strip, demonstrating a patient in normal sinus rhythm with significant pathological findings. The tracing reveals deep, pathological Q waves and poor R-wave progression across the precordial leads (V1 to V4), indicative of transmural myocardial necrosis. Associated ST-segment elevation and T-wave inversion are observed in the anterior-lateral leads (V1-V6), suggesting an ongoing or recent myocardial injury/infarct pattern. These findings are clinically significant for identifying a localized area of scarring and active ischemia in the anterior-lateral left ventricular wall. The modality is a diagnostic ECG on standard grid paper (25 mm/sec, 10 mm/mV), which is a critical tool for medical students and clinicians in identifying ischemic heart disease and localizing myocardial infarction.

I now have all the data needed for a thorough answer. Let me compose the full clinical analysis.

ECG Analysis & Clinical Management

ECG Interpretation (Machine + Visual Analysis)

The machine report flags this as an Abnormal ECG with the following key findings:

1. Sinus Rhythm at 60 bpm

  • Normal rate, regular rhythm. P waves present and preceding each QRS.

2. QRS Axis: -10° (Left Axis Deviation, borderline)

  • Mild left axis deviation. Can be seen with left anterior fascicular block, LVH, or inferior wall scar.

3. Possible Anterior Infarct - Age Undetermined

  • The precordial leads (V1-V3/V4) likely show poor R-wave progression (PRWP) - R waves fail to grow appropriately across the chest leads. This is the hallmark of an old/prior anterior MI (especially LAD territory). Without ST elevation, this is more consistent with an old anterior wall MI rather than an acute event.
  • The phrase "age undetermined" means the machine cannot tell if this infarction is old (weeks/months/years) or recent.

4. Inferior/Lateral ST-T Abnormality (Nonspecific)

  • Marked as nonspecific (~), meaning ST or T-wave changes in inferior (II, III, aVF) and lateral (aVL, V5-V6) leads that do not meet strict STEMI criteria. Could represent:
    • Ischemia
    • LVH strain pattern
    • Electrolyte imbalance
    • Hypertensive changes

5. Low QRS Voltages in Precordial Leads

  • RV5+SV1 = 0.889 mV (very low; Sokolow-Lyon criteria for LVH requires >3.5 mV)
  • Low precordial voltage causes include:
    • Prior anterior MI with scar (most likely here)
    • Pericardial effusion
    • Obesity / COPD / emphysema (poor R-wave for different reason)
    • Dilated cardiomyopathy
    • Hypothyroidism

6. Slightly Wide QRS (106 ms)

  • Borderline prolonged but does not meet full LBBB/RBBB criteria. May reflect incomplete bundle branch block or delayed conduction from myocardial scar.

Clinical Correlation with Patient Presentation

Symptoms: Vertigo + Vomiting BP: 150/90 mmHg (Stage 1-2 Hypertension) Background medications visible: Diabride-M (Glimepiride + Metformin) and Emparo-L (likely Empagliflozin + Losartan/Lisinopril) -- indicating the patient has known Diabetes Mellitus and is likely on an ARB/ACE-I.

Possible Diagnoses (Differential)

PriorityDiagnosisRationale
1stBenign Paroxysmal Positional Vertigo (BPPV)Most common cause of acute vertigo + vomiting; ECG abnormalities would be incidental
2ndVertebrobasilar TIA / Posterior Circulation IschemiaVertigo + vomiting + hypertension in a diabetic patient with prior cardiac history = must rule out
3rdLabyrinthitis / Vestibular NeuritisAcute onset, viral, less concerning but diagnosis of exclusion
4thOld Anterior MI with Systolic Dysfunction (HFrEF)Low voltage + prior infarct pattern on ECG could cause dizziness if EF is reduced
5thHypertensive VertigoBP 150/90 can occasionally cause vertiginous symptoms; also raises stroke risk
6thDrug-related (Antihypertensive side effect)Empagliflozin/Losartan can cause postural hypotension leading to dizziness
The ECG pattern (possible old anterior MI + low voltage + ST-T changes) in a known diabetic with hypertension presenting with vertigo and vomiting makes posterior circulation stroke/TIA a high-priority diagnosis to exclude - these patients can have "silent" prior MI and present atypically.

Recommended Investigations

Urgent / Emergency

  • MRI Brain with DWI (diffusion-weighted) - gold standard for posterior fossa stroke/TIA
  • CT Brain - if MRI not immediately available
  • Troponin I/T (serial) - rule out NSTEMI (vertigo can be an atypical MI presentation in diabetics)
  • 12-lead ECG repeat + comparison with any prior ECG
  • Blood glucose (hypoglycemia can mimic vertigo)
  • Electrolytes (Na, K, Mg) - especially relevant with SGLT2i use
  • Renal function (Cr, BUN, eGFR)

Non-urgent but Important

  • 2D Echocardiogram - assess LV function, wall motion abnormalities (prior anterior MI?), pericardial effusion (to explain low voltage)
  • Holter monitor - if paroxysmal arrhythmia suspected as cause of dizziness
  • Lipid profile, HbA1c
  • Thyroid function (TSH) - hypothyroidism can cause low voltage ECG

Risk Factors Summary

Risk FactorEvidence
Diabetes MellitusOn Glimepiride + Metformin + Empagliflozin
HypertensionBP 150/90; on ARB/SGLT2i
Likely prior anterior MIECG pattern (poor R-wave progression, possible old infarct)
AtherosclerosisCombination of DM + HTN = high cardiovascular risk
Age (undetermined from ECG)Consistent with middle-to-older adult profile

Suggested Treatment Plan

Immediate (Emergency Department)

  1. Stabilize and monitor - continuous cardiac monitoring, pulse oximetry, IV access
  2. Anti-vertigo therapy:
    • Tab. Betahistine 16 mg TID (for BPPV/vestibular cause)
    • IV/IM Promethazine 25 mg or Ondansetron 4 mg IV for vomiting
    • Avoid Diazepam if posterior stroke is suspected (masks cerebellar signs)
  3. BP management:
    • If posterior stroke confirmed: permissive hypertension (keep SBP <180 unless hemorrhagic)
    • If no stroke: optimise existing antihypertensives (continue Losartan/Empagliflozin)
    • Do NOT aggressively drop BP acutely if perfusion is at risk

Cardiac-Specific

  1. If troponin elevated (NSTEMI):
    • Dual antiplatelet (Aspirin 300 mg loading + Clopidogrel 75 mg)
    • Anticoagulation (LMWH/fondaparinux)
    • Cardiology consultation for early invasive strategy
  2. If old MI confirmed on Echo (reduced EF):
    • Ensure on ACE-I/ARB (already on Losartan - continue)
    • Add beta-blocker (Carvedilol or Metoprolol) if not already prescribed
    • Statin therapy (if not already on one - high-intensity, e.g. Atorvastatin 40-80 mg)
    • Empagliflozin already provides cardiac benefit in diabetics with HFrEF

Neurology

  1. If posterior circulation TIA/stroke confirmed:
    • Aspirin 300 mg loading, then 75 mg OD
    • Statin
    • Strict BP control (long-term target <130/80 in diabetic + cerebrovascular disease)
    • Neurology/Stroke team referral

Diabetes Management

  1. Continue Glimepiride + Metformin + Empagliflozin (already appropriate for a diabetic with cardiovascular risk; Empagliflozin has proven cardioprotective benefit)
  2. Check glucose - avoid hypoglycemia (can precipitate dizziness and arrhythmias)

Long-term

  1. Lifestyle: Low-sodium diet, weight management, regular moderate exercise
  2. Target BP: <130/80 mmHg (diabetic with cardiac disease)
  3. HbA1c target: <7% ideally
  4. Repeat ECG in 1-2 weeks and cardiologist follow-up for formal ECG interpretation with age/gender data

Key Bottom Line

This patient is a known diabetic with hypertension presenting with vertigo and vomiting. The ECG shows a possible old anterior MI (poor R-wave progression, low precordial voltage, nonspecific ST-T changes) in sinus rhythm at 60 bpm. The ECG alone does not indicate an acute STEMI, but posterior circulation stroke/TIA must be urgently excluded via MRI brain DWI. Serial troponins are essential to rule out NSTEMI. A 2D echocardiogram is needed to assess LV function and explain the low voltage pattern.
