Abstract Low-voltage on the surface electrocardiogram ECG is classically defined as peak-to-peak QRS voltage less than 5 mm in all limb leads and less than 10 mm in all precordial leads. There are three general processes that contribute to low QRS voltage: Damping of the electrical signal due to excess air emphysemaCOPDfluid pericardial effusionpericardial constrictionpleural effusionedema anasarcafat obesityor amyloid cardiomyopathy Electrically inert myocardium due to a loss of viable myocardium such as in myocardial infarction and Chagas disease]] Infiltration of the myocardium myxedematousChagas disease Causes of Low QRS Voltage The presence of low voltage on the EKG should prompt an evaluation to rule out life threatening emergencies such as cardiac tamponade or a large pericardial effusion.
INTRODUCTION: Low voltage on the surface electrocardiogram (ECG) is defined as QRS voltage less than 5 mm in all limb leads and less.
Low voltage on the ECG is defined as a peak-to-peak QRS amplitude of less than 5 millimeters in the limb leads and/or less than 10 millimeters in the precordial. ECG; Low QRS voltage; Causes of low QRS voltage; Passive body volume conductor; Electrical limb leads with high QRS complexes in the precordial leads.

Low QRS Voltage.
Electrocardiogram voltage discordance interpretation of low QRS voltage only in the limb leads.
Amplitudes of all the QRS complex amplitude limb leads < 5 mm; precordial leads < 10 mm e.g. pericardial effusion. Low voltage of the limb leads is present when the amplitude of the QRS complex in each of the three standard limb leads (I, II, and III) is <5 mm.
The first, third and fifth beat of V4 are 7 mm while the second and fourth beats are only 3 mm in amplitude.

The combination of low voltage and electrical alternans is suggestive but not diagnostic of a pericardial effusion or tamponade, but would be particularly suggestive in the setting of shortness of breath, tachycardia and low blood pressure.

Because the fluid around the heart impairs filling of the heart, the jugular venous pressure will be elevated and jugular veins will be distended.
