Previous attempts to measure high-frequency QRS potentials have been limited by methodologic difficulties in accurately quantitating these low-amplitude potentials. Therefore, we sought a simple, yet quantitative index of high-frequency ECG voltage.

To assess the reliability of using ejection fraction values derived from gated blood pools scans as a way to classify patients, we reviewed 76 radionuclide studies. Each study was processed in 10 different ways (varying or fixed left ventricular regi

The first derivative (dVdt) of the QRS complex has been used to assess high-frequency QRS notching. However, prior investigators did not evaluate the amplitude of QRS dVdt. Theoretically, myocardial infarction should decrease QRS dVdt by slowing vent
