•
Finding
Synonyms: Low QRS Voltage; Low QRS Voltage by ECG Finding; Low QRS Voltage by EKG Finding; Low QRS voltages
SNOMED CT: Low QRS voltages (251146004)
 
HPO: HP:0025077

Definition

Reduced amplitude (height) of the QRS complex of the electrocardiogram (EKG), defined as amplitudes of all the QRS complexes in the limb leads are less than 5 mm or amplitudes of all the QRS complexes in the precordial leads less than 10 mm. [from HPO]
