Top 10 Heart Diseases — ECG Findings & Images

1. 🔴 ST-Elevation Myocardial Infarction (STEMI)

ECG Findings:

Feature	Description
Rhythm	Sinus (may develop VT/VF)
ST Segments	Convex (tombstone) ST elevation ≥1 mm in ≥2 contiguous leads
Reciprocal Changes	ST depression in opposing leads
Hyperacute T-waves	Tall, peaked T-waves (earliest sign)
Q Waves	Pathological Q waves develop later (necrosis)
Territory	Anterior (V1–V6, LAD), Inferior (II, III, aVF, RCA), Lateral (I, aVL, V5–V6)

Key teaching point: ST elevation in V2–V4 = LAD occlusion; II, III, aVF = RCA occlusion. Reciprocal depression confirms STEMI.

Anterior STEMI: ST elevation V1–V6, convex morphology, indicative of LAD occlusion

Inferolateral STEMI: ST elevation in II, III, aVF, V4–V6 with reciprocal depression in I and aVL

2. 💜 Atrial Fibrillation (AF)

ECG Findings:

Feature	Description
Rhythm	Irregularly irregular — no two R-R intervals equal
P Waves	Absent; replaced by chaotic fibrillatory (f) waves
QRS	Narrow (unless aberrant conduction/WPW)
Rate	Ventricular rate varies; may be slow, normal, or fast
Baseline	Fine or coarse f-waves, best seen in V1 and II

Key teaching point: "Irregularly irregular + no P waves = AF." Rate control target is 60–100 bpm at rest.

AF with rapid ventricular response: ~126 bpm, irregular R-R, absent P waves, fine f-waves in V1

Coarse AF: prominent f-waves in V1 may mimic atrial flutter — note variable baseline

3. 💛 Ventricular Tachycardia (VT)

ECG Findings:

Feature	Description
Rhythm	Regular (monomorphic) or irregular (polymorphic/torsades)
Rate	100–250 bpm
QRS	Wide (>120 ms), bizarre morphology
P Waves	AV dissociation — P waves independent of QRS
Fusion/Capture Beats	Pathognomonic of VT
Axis	Often extreme left (northwest) axis

Key teaching point: Wide complex tachycardia is VT until proven otherwise. Brugada criteria help differentiate VT from SVT with aberrancy.

Monomorphic VT: wide QRS, no P waves, positive concordance in precordial leads, regular rapid rhythm

4. 💚 Complete (Third-Degree) Heart Block

ECG Findings:

Feature	Description
Rhythm	P waves regular; QRS independent (AV dissociation)
Rate	Atrial rate > ventricular rate
PR Interval	No fixed PR interval
QRS	Wide if infranodal escape (junctional escape = narrow)
Ventricular Rate	20–40 bpm (ventricular escape)

Key teaching point: Complete AV dissociation with ventricular rate < atrial rate = third-degree block. Pacemaker required.

Third-degree AV block: P waves (arrows) march through independently, ventricular rate ~33 bpm, wide QRS escape rhythm

Complete heart block: Regular P waves at ~75 bpm, slow independent ventricular escape at ~40 bpm

5. 🟠 Hypertrophic Cardiomyopathy (HCM)

ECG Findings:

Feature	Description
LVH Voltage	High-amplitude QRS (Sokolow: SV1 + RV5/6 ≥ 35 mm)
T-Wave Inversions	Deep, symmetric ("giant") T-wave inversions V2–V6 (apical HCM/Yamaguchi)
Septal Q Waves	Deep, narrow Q waves in I, aVL, V5–V6 (septal hypertrophy)
ST Depression	Horizontal/downsloping in lateral leads
Rhythm	Sinus; AF common; risk of VT/VF

Key teaching point: Giant negative T waves ≥10 mm in precordial leads in apical HCM (Yamaguchi syndrome) is a classic ECG signature.

Apical HCM (Yamaguchi): Giant symmetric T-wave inversions in V4–V6 and limb leads, high-voltage QRS

6. 🔵 Wolff-Parkinson-White Syndrome (WPW)

ECG Findings:

Feature	Description
PR Interval	Short (<120 ms) — accessory pathway bypasses AV node
Delta Wave	Slurred upstroke at onset of QRS (pre-excitation)
QRS Duration	Wide (>120 ms) due to fusion beat
ST/T Changes	Secondary repolarization abnormalities (discordant)
Pseudo-infarct	Negative delta waves in inferior leads mimic Q waves
Risk	AF with rapid conduction → ventricular fibrillation (avoid AV nodal blockers)

Key teaching point: Short PR + delta wave + wide QRS = WPW. Posteroseptal pathway = negative delta in II, III, aVF.

WPW: Short PR interval, delta waves (red arrows in II and III), widened QRS — anteroseptal pathway

WPW with posteroseptal pathway: negative delta waves in inferior leads II, III, aVF (pseudo-infarct pattern)

7. 🟡 Acute Pulmonary Embolism (PE)

ECG Findings:

Feature	Description
Most Common	Sinus tachycardia (most sensitive but non-specific)
S1Q3T3	S wave in I + Q wave in III + T-wave inversion in III (classic)
RBBB	New incomplete or complete right bundle branch block
Right Axis Deviation	Shift from baseline axis
T-wave Inversions	V1–V4 (right ventricular strain)
P Pulmonale	Tall peaked P waves in II (right atrial strain)

Key teaching point: S1Q3T3 is specific (but insensitive ~20%). The most useful ECG finding is new sinus tachycardia with right-sided changes in a dyspneic patient.

Acute PE: Sinus tachycardia ~116 bpm, S1Q3T3 pattern, T-wave inversions V1–V3, incomplete RBBB

S1Q3T3 pattern annotated: S wave lead I (blue), Q wave lead III (red), inverted T lead III (yellow)

8. 🟣 Acute Pericarditis

ECG Findings:

Feature	Description
Stage 1	Diffuse saddle-shaped (concave) ST elevation in all leads except aVR and V1; PR depression
Stage 2	ST normalizes; T-wave inversions develop
Stage 3	Deep T-wave inversions
Stage 4	Normalization
Key Distinguisher	Diffuse ST elevation (no culprit vessel territory) + PR depression in II; PR elevation in aVR
Spodick's Sign	Downsloping TP segment

Key teaching point: PR depression in lead II with diffuse concave ST elevation distinguishes pericarditis from STEMI. No reciprocal changes (except aVR).

Acute pericarditis: Diffuse concave "saddle-shaped" ST elevation, PR depression in II, PR elevation in aVR, Spodick's sign

Classic pericarditis: diffuse ST elevation I, II, III, aVF, V2–V6 with PR depression — no territory-specific distribution

9. 🔶 Dilated Cardiomyopathy (DCM) / Congestive Heart Failure

ECG Findings:

Feature	Description
LVH Voltage	High QRS voltage (may be low voltage in advanced/amyloid)
LBBB	Left bundle branch block very common (QRS >120 ms, broad notched R in I, V5–V6)
Q Waves	May simulate old MI (pseudo-infarct)
AF	Frequent comorbid arrhythmia
Sinus Tachycardia	Compensatory
Prolonged QRS	Poor prognosis; candidate for CRT (cardiac resynchronization therapy)

Key teaching point: LBBB in a patient with reduced EF is an indication for CRT if QRS ≥150 ms. Low voltage in amyloid DCM contrasts with echocardiographic "sparkling" hypertrophy.

Dilated cardiomyopathy: High-voltage QRS with LVH pattern, ST-T wave abnormalities; echo shows dilated LV with poor systolic function

10. 🟤 Non-ST Elevation Myocardial Infarction (NSTEMI) / Unstable Angina

ECG Findings:

Feature	Description
ST Depression	Horizontal or downsloping ≥0.5–1 mm in ≥2 contiguous leads
T-wave Inversions	Symmetric, deep — especially in Wellens syndrome (V2–V3)
No ST Elevation	Key distinction from STEMI
Transient Changes	May normalize between episodes
Wellens Syndrome	Type A: biphasic T V2–V3; Type B: deep symmetric T inversion V2–V3 — proximal LAD lesion
Normal ECG possible	Up to 1–6% of NSTEMI have normal ECG

Key teaching point: Wellens syndrome T-wave pattern without chest pain at the time of ECG = critical proximal LAD stenosis requiring urgent cath — do NOT stress test.

Anterolateral STEMI/NSTEMI with Wellens-type changes

Anterolateral ischemia: ST elevation with reciprocal inferior depression — demonstrates territory-based ischemic changes

Quick Reference Summary Table

#	Condition	Rhythm	Key ECG Feature	Emergency Action
1	STEMI	Sinus	Convex ST elevation ≥1 mm	PCI within 90 min
2	Atrial Fibrillation	Irregularly irregular	No P waves, f-waves	Rate/rhythm control, anticoagulation
3	Ventricular Tachycardia	Regular, fast	Wide QRS >120 ms, AV dissociation	Cardioversion/amiodarone
4	Complete Heart Block	Slow ventricular escape	AV dissociation, no PR relationship	Temporary pacing
5	Hypertrophic CM	Sinus	Giant T inversions, LVH voltage	Beta-blockers, ICD if high risk
6	WPW	Variable	Short PR, delta wave, wide QRS	Ablation; avoid AV nodal drugs in AF
7	Pulmonary Embolism	Sinus tachycardia	S1Q3T3, RBBB, RV strain	Anticoagulation ± thrombolysis
8	Pericarditis	Sinus	Diffuse concave ST elevation, PR depression	NSAIDs + colchicine
9	Dilated CM / HF	Sinus/AF	LBBB, LVH, Q waves	Guideline-directed medical therapy, CRT
10	NSTEMI / Unstable Angina	Sinus	ST depression, T inversions (Wellens)	Antiplatelet, anticoagulation, early cath

Clinical pearl: Always compare the ECG with a prior baseline when available. Serial ECGs 15–30 minutes apart can reveal dynamic changes that confirm or exclude acute ischemia.
