ECG diagnosis
Ventricular hypertrophy
atrial hypertrophy
Left atrial hypertrophy
"Mitral P wave"
P wave widening, ≥0.12s, double peaks obvious, peak spacing ≥0.04s (obvious in leads I, II, aVL)
Not specific to left atrial hypertrophy
Right atrial hypertrophy
"Pulmonary P wave"
P wave is high and sharp, ≥0.25mV (obvious in leads II, III, and aVF)
Not specific to right atrial hypertrophy
Double room hypertrophy
P wave broadening ≥0.12s, amplitude ≥0.25mV
ventricular hypertrophy
left ventricular hypertrophy
QRS complex voltage increases: Rv5>2.5mV; Rv5 Sv1>4.0mV(male)/3.5mV(female)
ST-T secondary changes: The R wave is the main lead, the ST segment is depressed downward, >0.05mV, and the T wave is flat/bidirectional/inverted; S wave is the leading link, T wave is upright
right ventricular hypertrophy
QRS complex changes: R/S>1 in lead V1, showing R type, Rs type, qR type; Deepening of S wave in lead V5; R wave is dominant in lead aVR; Rv1 Sv5>1.05mV(severe>1.2mV)
Right deviation of the cardiac axis ≥90° (severe ≥110°)
Secondary ST-T changes
double chamber hypertrophy
Mild hypertrophy - cancel each other out, voltage is normal
Mainly on one side - showing ventricular hypertrophy on one side
Severe hypertrophy - dual chamber hypertrophy showing simultaneously
Myocardial infarction (MI)
Diagnostic basis - clinical manifestations, electrocardiogram (dynamic evolution), biochemical indicators
Types
STEMI (ST segment elevation myocardial infarction)
NSTEMI (non-ST segment elevation myocardial infarction)
basic graphics
ischemic type
Earliest—subendocardial—high tip of T wave
Subepicardial – T wave inversion
damage type
ST segment elevation
Necrotic type
Abnormal Q wave (time ≥ 0.04s, depth ≥ 1/4 of the R wave in the same lead)
installment
Hyperacute phase (early stage)
minutes to hours
The T wave is tall and upright, the ST segment is obliquely elevated, and there is no abnormal Q wave.
Acute phase (fully developed phase)
hours to days
Abnormal Q wave, ST segment arch and upward elevation, T wave inversion
Subacute phase (near term)
weeks to months
Abnormal Q wave, ST segment returning to baseline, T wave symmetrical inversion (coronal T)
Stale period (healing period)
Abnormal Q wave, ST segment baseline level, T wave upright or inverted
position
Abnormal Q wave appears
merge
Ventricular aneurysm - persistent elevation of ST segment for more than several months
Right bundle branch block: Initial ventricular depolarization—characteristics of myocardial infarction Terminal—Characteristics of right bundle branch block
Left bundle branch block: Myocardial infarction graphics are often concealed
Myocardial ischemia
Combined with clinical practice - dynamic changes
ECG type
ischemic type
Subendocardial ischemia - tall T wave
Subepicardial ischemia - T wave inversion
damage type
Subendocardial myocardial injury—ST segment depression
Subepicardial myocardial injury—ST segment elevation
clinical type
acute coronary insufficiency
Typical angina
Coronary artery stenosis Increased myocardial oxygen consumption
ST segment depression ≥0.05mV, T wave flat/bidirectional/inverted; returns to normal after attack
variant angina
transient coronary artery spasm
Temporary ST segment elevation and towering T wave
chronic coronary insufficiency
Persistent ST segment depression and/or T wave flattening/inversion
