What are the vectorcardiographic criteria for diagnosing left ventricular hypertrophy using the Frank lead system?
The study proposes five criteria for diagnosing left ventricular hypertrophy using spatial vectorcardiograms with the Frank lead system.
Varriale et al. (1966) conducted an observational in Left ventricular hypertrophy (n=50). Direct spatial vectorcardiograms using the Frank lead system was evaluated on Vectorcardiographic loop patterns and quantitative measurements. Direct spatial vectorcardiograms using the Frank lead system demonstrated three distinctive loop patterns, leading to five proposed criteria for diagnosing left ventricular hypertrophy.
