Microvoltages are present when the QRS amplitude (the sum of the negative and positive parts) does not exceed 0.5 mV in any of the limb leads or 1.0mV in any of the chest leads. | Microvoltages are present when the QRS amplitude (the sum of the negative and positive parts) does not exceed 0.5 mV in any of the limb leads or 1.0mV in any of the chest leads. | ||
