The lower R/T ratio inside a bore are obtained in patients with bathycardia, a condition in which the heart axis is close to the body axis. In addition, the short distance between the apex of the heart and the apex electrode and closeness of lead II and the heart axis are factors of a worse R/T ratio. These two points should be improved to obtain waveforms with a high R/T ratio.
