Table 2. Patient baseline clinical characteristics with respect to the medical specialty that indicates the 24H register.

Values are expressed as mean ± standard deviation unless otherwise stated. * p value of < 0.05 comparing Cardiology versus other medical specialties. AVB = Atrio-ventricular block; CRD = Chronic renal disease; EF = Left ventricular ejection fraction; HT = Hypertension; IVCD = Intra-ventricular conduction delay (QRS width of > 120 ms); LAD = Left atrial diameter; SA = Sleep apnea; SHD = Structural heart disease.
