What Is Low Voltage Qrs Mean. Low voltage on the ECG is defined as a peak-to-peak QRS amplitude of less than 5 millimeters in the limb leads andor less than 10 millimeters in the precordial leads. Conditions That Cause Abnormal Voltages of the QRS Complex.
Normally the voltages in the three standard bipolar limb leads as measured from the peak of the R wave to the bottom of the S wave vary between 05 and 20 millivolts with lead III usually recording the lowest voltage and lead II the highest. Sinus Bradycardia left axis low. Low voltage means that what are called the qrs complexes are smaller than usual.
The significance of low voltage of the QRS complexes in the limb leads of the electrocardiogram has been discussed by many observers.
Just a couple quick questions before I transfer you. I was advised that my PCP will need to clear me. COPD obesity and pericardial effusions. Low voltage QRS complexes part if the EKG tracing may be indicative of a weaker myocardium or the heart muscle.
