Electrocardiographic left ventricular hypertrophy (ECG LVH) holds significant clinical importance in cardiovascular disease. Pathological processes that lead to left ventricular hypertrophy (LVH) also induce remodeling and impair left atrial (LA) function. Atrial function can be assessed using speckle-tracking echocardiography. This study investigates the potential impact of ECG LVH on LA strain.

A total of 62 individuals diagnosed with LVH, based on the echocardiographic left ventricular mass index, were included. ECG LVH was assessed using established protocols: the Sokolow-Lyon voltage criteria (SV1 + RV5/RV6 > 35 mm), Cornell voltage criteria (RaVL + SV3 > 28 mm for men and > 20 mm for women), and the Cornell product criteria [(SV3 + RaVL + (for women 8 mm)] x QRS duration > 2440 mm x ms). Participants were categorized into two groups based on the presence or absence of ECG LVH. The relationship between LA strain measures and ECG characteristics was explored.

The study population had a median age of 58.3 ± 10.1 years, with 40.3% being female, 91.9% hypertensive, and 35.5% diabetic. Nineteen patients (30.6%) were identified with ECG LVH based on Sokolow-Lyon voltage, Cornell voltage, or Cornell product criteria. These patients exhibited significantly reduced LA reservoir, conduit, and contraction strains (P < 0.001). Statistically significant correlations were observed between all three phases of LA strain measures and Sokolow-Lyon voltage (reservoir r = -0.389, P < 0.01; conduit r = -0.273, P < 0.05; contraction r = -0.359, P < 0.01), Cornell voltage (reservoir r = -0.49, P < 0.001; conduit r = -0.432, P < 0.001; contraction r = -0.339, P < 0.01), and Cornell product (reservoir r = -0.471, P < 0.001; conduit r = -0.387, P < 0.01; contraction r = -0.362, P < 0.01).

ECG LVH is associated with impaired LA strain, validating its use as an effective tool for predicting LA dysfunction.
