ECG Criteria, method of assessing left ventricular ejection fraction (LVEF), and patient characteristics from previous studies correlating ECG findings with LV function^4‐9

Number	ECG criteria	ECG descriptor	Author	Method for assessing LV function	Patients studied (MI or No MI)
1	SV1 or SV2 + RV5 or RV6 ≥ 3.5 mV (Goldberger's first criterion)	Prominent precordial QRS amplitudes	Goldberger4	Echocardiography (LVEF)	Both
2	Mean QRS amplitude in each of the limb leads ≤ 0.8mv (Goldberger's second criterion)	Low voltage in limb leads
3	RV4/SV4 < 1 (Goldberger's third criterion)	Poor R‐wave progression
4	Goldberger's triad	Combination of all 3 Goldberger's criteria
5	Maximal QRS duration ≥ 124 ms	QRS duration	Cincin et al.5	Echocardiography (LVEF)	No MI
6	Maximal QRS duration + Goldberger's first criterion	QRS duration and prominent precordial QRS amplitudes
7	Maximal QRS duration + Goldberger's third criterion	QRS duration and low voltage in limb leads
8	Maximal QRS duration + Goldberger's first and third criteria	QRS duration, prominent precordial QRS amplitudes, and poor R‐wave progression
9	All voltage ratios of RV6/RI, RII, RIII ≥ 3	Prominent QRS voltage in precordial leads and low QRS voltage in limb leads	Momiyama et al6	Echocardiography	No MI (Dilated Cardiomyopathy)
10	Simplified Selvester QRS score ≥ 10 for LVEF ≤ 30 and Simplified Selvester QRS score ≥ 7 for LVEF ≤ 40	Scores based on Q wave duration and R/Q ratio in limb leads I,II, aVL, and aVF and Q wave duration and R/Q or R/S ratio in precordial leads	Bounous EP et al7 and Palmeri et al8	Multigated radionuclide angiography	Only MI
11	QRS voltage < 5 mm in all limb leads and > 10 mm in at least 2 contiguous precordial leads	Low voltage in limb leads without low voltage in precordial leads	Chinitz et al9	Echocardiography (LVEF)	Both
